<div style="float: right; margin-top: 5px; margin-left: 15px; margin-bottom: 15px; width: 450px;">__TOC__</div>

=={{SpanID|616.3.1}}616.3.1 Pedestrian and Worker Safety – General (MUTCD Section 6C.01)==

'''Standard.''' The various TTC provisions for pedestrian and worker safety set forth in [[:Category:616 Temporary Traffic Control (MUTCD Part 6)|EPG 616]] shall be applied by knowledgeable (for example, trained and/or certified) persons after appropriate evaluation and engineering judgment.

=={{SpanID|616.3.2}}616.3.2 Pedestrian Considerations (MUTCD Section 6C.02)==

'''Support.''' A wide range of pedestrians might be affected by TTC zones, including the young, elderly, and people with disabilities such as hearing, vision, or mobility. Pedestrians need a clearly delineated and usable travel path. Considerations for pedestrians with disabilities are addressed in [[#616.3.3|EPG 616.3.3]].

'''Guidance.''' Prior to closing a sidewalk or other pedestrian facility, the maintaining agency should advise users of the future closure.

'''Standard.''' If the TTC zone affects the movement of pedestrians, adequate pedestrian access and walkways shall be provided.

'''Option.''' If establishing or maintaining an alternate pedestrian route is not feasible during the project, an alternate means of providing for pedestrians may be used, such as adding free bus service around the project or assigning someone the responsibility to assist pedestrians with disabilities through the project limits.

<ol type="A">
<li>Long-term stationary work zones of two weeks or more resulting in substantial worker exposure to motorized traffic;</li>
<li>Projects with work zone operating speed limits of 45 mph or greater, especially when combined with high traffic volumes;</li>
<li>Work operations that place workers, pedestrians, or bicyclists close to travel lanes open to traffic; and</li>
<li>Roadside hazards, such as drop-offs or unfinished bridge decks, that will remain in place overnight or longer.</li>
</ol>

Temporary traffic barrier shall be required on the following:
<ol type="A">
<li>Roadway excavation edge drop-offs (refer to [https://www.modot.org/media/16895 Standard Plan 619.10]), and</li>
<li>Bridge rehabilitation jobs with bridge rail replacement and/or full depth repair.</li>
</ol>

'''Guidance.''' Temporary traffic barrier should be considered for long-term bridge repair work.

'''Support.''' When specified, quantities are calculated and shown on the plans. Delineators for temporary concrete traffic barriers are provided at no direct pay as shown on [https://www.modot.org/media/16894 Standard Plan 617.20] and stated in [https://www.modot.org/missouri-standard-specifications-highway-construction Specifications Section 617]. Delineators pay items are used only to retrofit existing permanent concrete traffic barrier.

Work zone setups vary depending on the nature of the positive protection used.

23 CFR Part 630.1108(a) contains additional requirements for certain projects.

'''Option. '''Temporary traffic barriers may be used to separate two-way vehicular traffic.

'''Standard. '''Temporary traffic barriers shall be supplemented with standard delineation, pavement markings, or channelizing devices for improved daytime and nighttime visibility if they are used to channelize vehicular traffic. The delineation color shall match the applicable pavement marking color.

Temporary traffic barriers, including their end treatments, shall be crashworthy (see definition in [[:Category:911 General (MUTCD Part 1)#Definitions_of_Words_and_Phrases_Used_in_this_Manual_(MUTCD_Section_1C.02)|EPG 911 (MUTCD Section 1C.02)]]).

Short intermittent segments of temporary traffic barrier shall not be used because they nullify the containment and redirective capabilities of the temporary traffic barrier, increase the potential for serious injury both to vehicle occupants and pedestrians, and encourage the presence of blunt leading ends. Adjacent temporary traffic barrier segments shall be properly connected in order to provide the overall strength required for the temporary traffic barrier to perform properly.

'''Guidance. '''Appropriate channelizing devices and pavement marking should always be used in front of barrier tapers for lane closures, shoulder closures or transition areas for temporary bypasses or connections. Wherever practical, a lateral shy distance should be provided between the edge of the driving lane and the barrier. A longitudinal buffer area should be provided between the channelizer taper and the barrier taper.

'''Support. '''Temporary traffic barrier includes portable concrete, portable steel, or movable barrier which can all be moved laterally and/or longitudinally when needed and/or from site to site. More specific information on the use of temporary traffic barriers is contained in Chapters 8 and 9 of “Roadside Design Guide,” 4th Edition, 2011, AASHTO and [[617.1 Temporary Traffic Barriers|EPG 617.1]].

=={{SpanID|616.13.3}}616.13.3 Temporary Raised Islands (MUTCD Section 6M.03)==

'''Standard. '''Temporary raised islands shall be used only in combination with pavement striping and other suitable channelizing devices'''.'''

'''Option. '''A temporary raised island may be used to separate vehicular traffic flows in two-lane, two-way operations on roadways having a vehicular traffic volume range of 4,000 to 15,000 average daily traffic (ADT) and on freeways having a vehicular traffic volume range of 22,000 ADT to 60,000 ADT.

Temporary raised islands also may be used in other than two-lane, two-way operations where physical separation of vehicular traffic from the TTC zone is not required.

'''Guidance. '''Temporary raised islands should have the basic dimensions of 4 inches high by at least 12 inches wide and have rounded or chamfered corners.

The temporary raised islands should not be designed in such a manner that they would cause a motorist to lose control of the vehicle if the vehicle inadvertently strikes the temporary raised island. If struck, pieces of the island should not be dislodged to the extent that they could penetrate the occupant compartment or involve other vehicles.

'''Standard. '''At pedestrian crossing locations, temporary raised islands shall have an opening or be shortened to provide at least a 60-inch wide passageway for the crossing pedestrian.

=={{SpanID|616.13.4}}616.13.4 Detectable Edging for Pedestrians (MUTCD Section 6M.04)==

'''Support. '''Individual channelizing devices, tape or rope used to connect individual devices, other discontinuous barriers and devices, and pavement markings are not detectable by persons with vision disabilities and are incapable of providing detectable path guidance on temporary or realigned sidewalks or other pedestrian facilities.

'''Guidance. '''A continuously-detectable edging should be provided throughout the length of a temporary pedestrian facility such that it can be followed by pedestrians using long canes for guidance. This edging should extend at least 8 inches above the surface of the sidewalk or pathway, with the bottom of the edging a maximum of 2 inches above the surface. This edging should be continuous throughout the length of the facility except for gaps at locations where pedestrians or vehicles will be turning or crossing. This edging should consist of a prefabricated or formed-in-place curbing or other continuous device that is placed along the edge of the sidewalk or walkway. This edging should be firmly attached to the ground or to other devices. Adjacent sections of this edging should be interconnected such that the edging is not displaced by pedestrian or vehicular traffic or work operations, and such that it does not constitute a hazard to pedestrians, workers, or other road users.

'''Support. '''Examples of detectable edging for pedestrians include:
:A. Prefabricated lightweight sections of plastic, metal, or other suitable materials that are interconnected and fixed in place to form a continuous edge.
:B. Prefabricated lightweight sections of plastic, metal, or other suitable materials that are interconnected, fixed in place, and placed at ground level to provide a continuous connection between channelizing devices located at intervals along the edge of the sidewalk or walkway.
:C. Sections of lumber interconnected and fixed in place to form a continuous edge.
:D. Formed-in-place asphalt or concrete curb.
:E. Prefabricated concrete curb sections that are interconnected and fixed in place to form a continuous edge.
:F. Continuous temporary traffic barrier or longitudinal channelizing barricades placed along the edge of the sidewalk or walkway that provides a pedestrian edging at ground level.
:G. Chain link or other fencing equipped with a continuous bottom rail.

'''Guidance. '''Detectable pedestrian edging should be orange, white, or yellow and should match the color of the adjacent channelizing devices or traffic control devices, if any are present.

=={{SpanID|616.13.5}}616.13.5 Crash Cushions (MUTCD Section 6M.05)==

'''Support. '''Crash cushions are systems that mitigate the effects of errant vehicles that strike obstacles, either by smoothly decelerating the vehicle to a stop when hit head-on, or by redirecting the errant vehicle. The two types of crash cushions that are used in TTC zones are stationary crash cushions and truck-mounted attenuators. Crash cushions in TTC zones help protect the drivers from the exposed ends of barriers, fixed objects, shadow vehicles, and other obstacles. Specific information on the use of crash cushions can be found in “Roadside Design Guide,” 4th Edition, 2011, AASHTO.

See [[617.1 Temporary Traffic Barriers|EPG 617.1]] and [[:Category:612 Impact Attenuators#612.1_Truck-Mounted_Attenuators|EPG 612.1]].

'''Standard. '''Crash cushions shall be crashworthy (see definition in [[:Category:911 General (MUTCD Part 1)#Definitions_of_Words_and_Phrases_Used_in_this_Manual_(MUTCD_Section_1C.02)|EPG 911 (MUTCD Section 1C.02)]]). They shall also be designed for each application to stop or redirect errant vehicles under prescribed conditions. Crash cushions shall be periodically inspected to verify that they have not been hit or damaged. Damaged crash cushions shall be promptly repaired or replaced to maintain their crashworthiness.

'''Support. '''Stationary crash cushions are used in the same manner as permanent highway installations to protect drivers from the exposed ends of barriers, fixed objects, and other obstacles.

'''Standard. '''Stationary crash cushions shall be designed for the specific application intended.

An approved crash cushion shall be installed on the exposed end of the barrier where the posted speed prior to construction on an existing facility or the anticipated posted speed of a temporary facility is greater than 35 mph. A crash cushion shall be installed on the upstream end for divided facilities, and on both ends for all two-way facilities.

Truck- or trailer-mounted attenuators shall be energy-absorbing devices attached to the rear of shadow trucks and shall be used in accordance with the manufacturer’s specifications. If used, the shadow vehicle with the attenuator shall be located in advance of the work area, workers, or equipment to reduce the severity of rear-end crashes from errant vehicles.

'''Support. '''See [[:Category:612 Impact Attenuators|EPG 612]] for the use of protective vehicle and truck/trailer-mounted attenuators.

Trucks or trailers are often used as shadow vehicles to protect workers or work equipment from errant vehicles. These shadow vehicles are normally equipped with flashing arrows, changeable message signs, and/or high-intensity rotating, flashing, oscillating, or strobe lights and are located properly in advance of the workers and/or equipment that they are protecting. However, these shadow vehicles might themselves cause injuries to occupants of the errant vehicles if they are not equipped with truck-mounted attenuators.

'''Guidance. '''The shadow truck should be positioned a sufficient distance in advance of the workers or equipment being protected so that there will be sufficient distance, but not so much so that errant vehicles will travel around the shadow truck and strike the protected workers and/or equipment.

'''Support. '''Chapter 9 of “Roadside Design Guide,” 4th Edition, 2011, AASHTO contains additional information regarding the use of shadow vehicles.

=={{SpanID|616.13.6}}616.13.6 Temporary Transverse Rumble Strips (MUTCD Section 6M.06)==

'''Support. '''Temporary rumble strips are a strategy for reducing distracted driving and achieving MoDOT’s work zone safety goals. Temporary rumble strips are used in construction or maintenance work zones (planned and unplanned) and consist of temporary long-term rumble strips.

Temporary rumble strips (see [https://epg.modot.org/forms/JSP/JSP1304.docx JSP-13-04C]) are comprised of a series of elongated strips installed laterally within the travel lane of the roadway to provide an audible and vibratory alert to drivers of the upcoming work zone.

Temporary long-term rumble strips are installed using adhesive backing on each strip to prevent movement of the strips in the travel lane.

'''Standard. '''If the color of a transverse rumble strip used within a travel lane is not the color of the pavement, the color of the rumble strip shall be orange.

When temporary long-term rumble strips are used, installation shall consist of a minimum of 1 set (5 strips per set) per open lane, spaced in accordance with [[#fig616.13.6.1|Figure 616.13.6.1]] on center with the RUMBLE STRIPS AHEAD sign.

If temporary rumble strips are used in work zones, any damage done to pavement shall be restored to the existing condition.

===616.13.6.1 Temporary Rumble Strips for Work Zones===

'''Standard. '''Temporary long-term rumble strips shall be used in long-term stationary daytime or night-time work zones with a duration of 3 days or more when a lane(s) is impacted.

'''Guidance. '''If the project is a long-term stationary project with intermediate construction activities impacting traffic, such as lane restrictions, additional temporary rumble strips should be evaluated for use.

'''Support. '''When temporary long-term rumble strips are included in projects performed by contractors, Job Special Provisions (JSPs) for temporary rumble strip used is required. Additional information, including maintenance, repair, and monitoring of temporary rumble strips, can be found in [https://epg.modot.org/forms/JSP/JSP1304.docx JSP-13-04C].

===616.13.6.2 Placement of Temporary Rumble Strips for Work Zones===

'''Support. '''Generally, temporary rumble strips are placed before the feature requiring attention (e.g., merge, lane shift, reduced speed) giving the motorist enough time to act safely. The recommended distance before the feature should be referenced or shown on the plans or figures. The location should be adjusted when needed to comply with the guidance below or based on performance observations.

'''Standard. '''Temporary rumble strips shall be placed perpendicular to traffic.

'''Guidance. '''The following information is applicable to temporary long-term rumble strips, except where noted.
:A. Temporary rumble strip placement should be reviewed, and consideration given to geometric conditions prior to placement.
:B. Temporary rumble strips should be place on tangent roadway segments. Placement at or just beyond a vertical curve crest should be avoided.
:C. Temporary rumble strips work best when in complete contact with the roadway surface and therefore should not be used on heavily rutted roadways or on roadways with loose material.
:D. Temporary rumble strips should not be placed through marked pedestrian crossings, marked pedestrian paths, or on marked bicycle routes. Engineering judgment should be used to avoid placement in these areas.
:E. Temporary rumble strips should not be placed where routine braking is expected on the rumble strip. Routine braking on the strips may cause the strips to come loose and require additional maintenance than otherwise would be needed to keep them in place. Relocating the rumble strips should be considered if constant maintenance is required.
:F. Additional sets of temporary long-term rumble strips should be used to get the attention of drivers.

'''Standard. '''Temporary rumble strips shall be checked, as necessary, for proper adhesion and corrected when needed. If temporary rumble strips are omitted as directed by this standard or field conditions, the decision with explanation of why, shall be documented accordingly.

=={{SpanID|616.13.7}}616.13.7 Screens (MUTCD Section 6M.07)==

'''Support. '''Screens are used to block the road users’ view of activities that can be distracting. Screens might improve safety and motor vehicle traffic flow where volumes approach the roadway capacity because they discourage gawking and reduce headlight glare from oncoming motor vehicle traffic.

See [[617.1 Temporary Traffic Barriers|EPG 617.1]] for additional information.

'''Guidance. '''Screens should not be mounted where they could adversely restrict road user visibility and sight distance and adversely affect the operation of vehicles.

'''Option. '''Screens may be mounted on the top of temporary traffic barriers that separate two-way motor vehicle traffic.

'''Guidance. '''Design of screens should be in accordance with Chapter 9 of “Roadside Design Guide,” 4th Edition, 2011, AASHTO.

=={{SpanID|616.13.8}}616.13.8 Lighting for Night Work (MUTCD Section 6M.08)==

'''Support. '''Utility, maintenance, or construction activities on highways are frequently conducted during nighttime periods when vehicular traffic volumes are lower. Large construction projects are sometimes operated on a double-shift basis requiring night work (see [[616.14 Types of Temporary Traffic Control Zone Activities (MUTCD Chapter 6N)#616.14.18|EPG 616.14.18]]).

'''Guidance. '''When nighttime work is being performed, floodlights should be used to illuminate the work area, equipment crossings, and other areas.

When used, floodlighting should be installed in a manner that minimizes glare to approaching road users, flaggers, or workers.

The adequacy of the floodlight placement and elimination of potential glare should be determined by driving through and observing the floodlighted area from each direction on all approaching roadways after the initial floodlight setup, at night, and periodically. Lighting should be sufficient so as to give road users the capability to identify a worker as a person. Care should be taken to minimize the potential for shadows to conceal workers within the work area.

'''Support. '''Desired work area illumination levels vary depending upon the nature of the task involved. An average horizontal luminance of 5 foot candles can be adequate for general activities. Tasks requiring high levels of precision and extreme care can require an average horizontal luminance of 20 foot candles.

'''Option. '''Typical work area lighting installations may include dirigible lighting, portable light towers, balloon lighting, lights attached to equipment or post-mounted lights. In some cases, existing lighting or ambient lighting may meet lighting level requirements and negate the need for including work zone lighting.

'''Support. '''Temporary fixed lighting illuminates specific areas of significance to guide road users within the TTC zone during nighttime hours.

'''Option. '''Temporary fixed lighting may be considered at gore areas, transitions, ingress and egress areas, equipment crossings, intersections, temporary signals, islands temporary bypasses, and crossovers. Temporary fixed lighting may also be considered for areas of potential conflict, such as temporary ramps, intersections, and one-lane, two-way traffic operations that are in place for more than 15 consecutive days. These conditions may require lighting even though the work may not be conducted at night. This type of lighting, while more difficult to design and install, provides more uniform light distribution thereby enabling the motorist to better navigate the work zone at night.

'''Guidance. '''When stationary operations exceed 15 consecutive days, such as a bridge replacement, interchange or intersection work that occurs at night, temporary fixed lighting should be considered in lieu of work zone lighting.

'''Standard. '''If temporary fixed lighting is used, it shall be designed and shown in the plans.

'''Support. '''Refer to [https://www.modot.org/missouri-standard-specifications-highway-construction Specifications Section 901] for roadway lighting requirements and [[:Category:901 Lighting|EPG 901]] for lighting design.

'''Standard. '''Except in emergency situations, flagger stations shall be illuminated at night.

===616.13.8.1 Fleet Lighting===

'''Support. '''Fleet lighting increases the visibility of work or incident response vehicles and equipment while in the temporary traffic control zone.

'''Standard. '''Except as provided in the following paragraph, all work vehicles and equipment shall be equipped with an acceptable warning light system, per example USDOT-approved warning lights. These lights shall be activated whenever a vehicle or piece of equipment is engaged in a work zone or incident response operation within the temporary traffic control zone.

'''Option. '''Vehicles and pieces of equipment may operate without warning lights activated if the vehicles and equipment are located within a workspace delineated by channelizers or protected by a temporary traffic barrier. For this situation, activation of the lights is not required.

'''Support. '''For Maintenance lighting requirements, see [[616.31 MoDOT Fleet Lighting|EPG 616.31]]. For construction projects see [[616.23 Construction Inspection Guidelines for Sec 616|EPG 616.23]].

=={{SpanID|903.8.9}}903.8.9 Project Information Sign (CONST-5) (MUTCD Section 2H.09)==

[[File:const-5_11-27.png|thumb|center|300px|alt=|<center>'''CONST-5'''</center>]]

'''Support.''' The Project Information (CONST-5) sign provides limited information to road users about a highway construction project on which work is imminently forthcoming or ongoing.

'''Guidance.''' The Project Information sign should be used on projects that last more than one construction season and are deemed prominent by the district. This sign should not be used on roadways that are closed to traffic or where the construction has no effect on existing roadways.

The Project Information sign should be placed in a visible area within the project’s limits provided its placement does not disrupt a sequence of signs (e.g., between ROAD WORK AHEAD, RIGHT LANE CLOSED AHEAD and RIGHT LANE CLOSED). See support figure Begin/End of Project Signing.

Project Information signs come in two sizes: 96 in. x 48 in. and 48 in. x 36 in. The larger sign should be used except where there is insufficient right of way for placement. Due to the sign’s width, flatter areas are preferable for placement to avoid long signpost lengths.

'''Standard.''' The Project Information sign legend shall be limited to the following project information:
# The roadway name or route number,
# A brief description or title of the project.
# The completion date expressed in either a month or season (Spring, Summer, Fall, or Winter).
# The agency name.

'''Option.''' Project Information signs installed more than one week prior to commencement of work may include a start date.

'''Standard.''' Project Information signs shall not be installed more than one month prior to the commencement of work. When installing Project Information signs prior to the commencement of work, the jurisdiction shall have a policy on when the Project Information signs are to be installed. Project Information signs shall be removed at the conclusion of work on the project, even if the final inspection or project closeout has not yet occurred.

The number of Project Information signs shall be limited to one per direction of travel on the roadways on which the project is based. The location of the Project Information sign shall not interfere with the temporary traffic control zone devices.

The Project Information sign shall have a white legend on a green background and shall not display Internet addresses, e-mail addresses, or telephone numbers (see [[903.1 General (MUTCD Chapter 2A) #903.1.4|EPG 903.1.4]]).

<div style="float: right; margin-top: 5px; margin-left: 15px; margin-bottom: 15px; width: 450px;">__TOC__</div>

==106.3.2.101.1 Scope==

Concrete aggregates, such as limestones and dolomites, usually contain high carbonate (calcium and magnesium) concentrations. This makes it extremely difficult to achieve complete fusion of sample(s) using a lithium metaborate (LiBO2) flux and dissolving the fused pellet in a weak nitric acid solution. By running the LOI, moisture and carbon dioxide (CO2), can be removed and the remaining inorganic residue can be adjusted to allow for better dissolution of sample(s).

==106.3.2.101.2 Equipment==

Platinum crucible, 20-ml capacity used only for aggregates

Porcelain crucible, 15-ml capacity used only for fly ash and natural pozzolans

Muffle furnace, 1000 degrees C temperature capacity

Spatula, approximately 6 inches in length

Analytical balance, capable of weighing 4 places past the decimal point

Inductively Couple Plasma Optical Emmission Spectrometer (ICP-OES)

Graphite crucible, used to fuse sample with a bed of LiBO2 contained in the crucible

Lithium metaborate (LiBO2), ACS anhydrous grade

Nitric acid (HNO3), certified ACS plus grade

Yttrium (Y), 1000 ppm liquid standard, 250-ml

¼ teaspoon, leveling knife and test tube with same diameter of the graphite crucible to fuse sample

Polypropylene beaker, 250-ml capacity

Filter paper, ashless #41, 110 mm diameter

Glass filter funnel

200-ml volumetric flask with graduated mark

==106.3.2.101.3 Method==

Obtain a clean, dry platinum crucible and weigh on an analytical balance. Record the weight to 4 places past the decimal point. Add 1 gram of sample to the initial weight of the crucible and record. Weigh sample to initial weight plus 1 gram in the platinum crucible to +/- 0.0005. Place crucible and sample contents into a cool muffle furnace. Bring temperature to 1000 degrees C (+/- 50 degrees) and keep in muffle furnace for 2 hours. After 2 hours, carefully remove crucible with tongs and place in desiccator to cool. Once crucible is cool, weigh to constant weight and record weight.

Place a ¼ teaspoon of LiBO2 into a graphite crucible and press down using a test tube to make a bed of LiBO2. Weigh LOI ignited material from the example calculation listed below and cover sample with a ¼ teaspoon of LiBO2 to encapsulate sample. Using tongs, place graphite crucible in a 1000 degree C muffle furnace for 20 minutes. After 20 minutes, carefully remove graphite crucible with tongs, swirl fused bead to obtain any fused particles indirect of the fused bead, and drop fused bead directly into a polypropylene beaker containing 150-ml 1:24 HNO3. Using a spatula, carefully scrape any remaining residue left in the graphite crucible and transfer to beaker. Place beaker on stir plate for a minimum of 5 minutes. Set-up filter funnel with a #41 filter paper and place 200-ml volumetric flask with 1-ml Yttrium added to the flask. Remove beaker from stir plate and filter into 200-ml volumetric flask. The filter removes any carbon from the solution. Quantitatively wash beaker twice with 1:24 HNO3 and dilute to volume. Analyze for selected analytes in solution using existing test template set in the ICP-OES software for aggregate analysis.

==106.3.2.101.4 Calculation==

Initial weight – final weight x 100 = % LOI

Once LOI has been determined, adjust weight of 0.2 +/- 0.0005 to LOI result and record.

'''Example:''' If % LOI is 42.00, subtract 100-42.00 = 58.00, multiply 0.2 +/- 0.0005 x .58 = 0.116 grams. This is the LOI corrected weight to fuse with LiBO2.

Perform the same method for standards and use the same test template on the ICP-OES to obtain concentration of selected analytes in solution

'''Note: This method can be used on other materials, such as high carbon Class C, F ashes, and natural pozzolans.'''

==106.3.2.101.5 Synopsis==

By removing the moisture and CO2, samples can be fused, dissolved, and the proper % recovery of the sample can be achieved.

|}
'''Support.''' This subarticle is a starting point for installations and other steps needed to successfully implement the flashing yellow arrow (FYA) for left turns at signalized intersections. The flashing yellow arrow has replaced the circular green ball for the permissive movement for left turns.

'''Standard.''' The turning movement for FYA operation must have a separate signal head. Shared indications are not allowed.

'''Support.''' Verify the installation of a stacked 4-section head is possible at a location with an existing 5- or 3-section head. If the turn head has a circular green being shared as the 2nd through indication, then a dedicated signal head will be needed for the 2nd through. Check field wiring to ensure there are enough dedicated conductors to drive the new signal heads. More conductors will be needed for a FYA head than a 5-section head, since each indication must be driven from the cabinet and not jumpered off the adjacent through.

'''Standard.''' A LEFT TURN YIELD ON FLASHING YELLOW ARROW (R10-12a) sign shall be mounted adjacent to the head.

When a new signal is being built or where an existing signal is being reconstructed, the FYA shall be used for the permissive left turn movement. All new cabinets shall be configured for FYA operation on all left turns.

'''Support.''' Verify the sign can be installed. Any existing left turn sign will need to be removed.

===902.23.5.1 Installation Strategy and Guidelines===

'''Guidance.''' Carefully considering where to first install the FYA can help with public acceptance. The Left Turn Phasing Warrants (safety and capacity) worksheet should be help determine what type of left turn signal phasing should be used.

The FYA will likely require a 16-position backpanel at locations with any current or anticipated signalized pedestrian control and/or dedicated overlaps, where pedestrian channels are put in the last 4 channels. However, the FYA components, if not immediately used, should be deactivated for future use.

'''Support.''' Run “Left Turn Phasing warrants” worksheet for safety and capacity warrants.
Volume. Collect volume data for each approach where the FYA will be installed. This includes at a minimum, the proposed left turn movement and opposing through volumes during times where phasing may possibly change.

For each FYA approach, enter the relevant data into the “Left Turn Phasing” worksheet to determine 24 hour-by-hour what phasing option can be used. Follow recommended phasing choice for each hour.

If on an approach the number of “protected-only” hours in a day are numerous, then consideration to full-time “protected-only” phasing should be given.

====902.23.5.1.1 Removing Protected-Only Turn Phasing: When Not To====

'''Standard.''' Protected-only left turn phasing shall not be removed if opposing sight distance is inadequate for permissive left turns, operating speed is too great, or there are too many opposing through lanes. The Left Turn Safety Warrants still apply.

'''Guidance.''' If the approach passes Left Turn Safety Warrants, exercise engineering judgment before going from protected-only to FYA protected-permissive. Consider whether the protected-only left turn was installed for other safety reasons (crash prevention when under less restrictive phasing), before operating a possible FYA installation protected-permissive.

====902.23.5.1.2 Installation – Best Candidates====
'''Guidance.''' When considering locations for initial installation look for:

:a) Isolated signals OR

:b) Adjacent signals within a coordinated signal corridor within common political boundaries (minimum two signals) AND

:c) One of the following conditions for each of the signals:

::* Mainline left turn approach(es) that currently operate protected/permissive.

::* Mainline permissive-only left turn approach(es) having the capability to run part-time protected/permissive or protected-only.

Upgrading sidestreet approaches as well at these chosen signals is preferred.

Additional installations could also include:
* Adjacent signals to first installation and possibly across another political boundary

* Another corridor in another political entity well away from other upgraded locations

* Nearby coordinated corridor with heavy protected-permissive left turn phasing

===902.23.5.2 Equipment for Reconstructed Signals===

'''Support.'''

:'''Cabinet.''' Examine the existing cabinet to determine how many load switch bays are unused and how many pedestrian load switches are in operation. Each FYA approach will require either one open load switch OR one in-use pedestrian load switch (to utilize the unused yellow channel) in addition to the current load switch for a protected permissive turn.

:'''Cabinet Modification.''' Contact the cabinet vendor to provide red-lined cabinet prints that will show the needed changes. Once installation is completed, acquire 4 clean prints that reflect the final modifications.

:'''Controller.''' Controller must be capable of FYA operation. Some controllers are too old to be upgraded to FYA operation. If utilizing an existing controller, check with controller’s vendor for capability.

:'''Conflict Monitor.''' FYA operation requires a special conflict monitor. Check with signal equipment vendors for applicable models. Consider purchasing backup conflict monitors so if the installed model fails, an applicable conflict monitor is immediately available.

===902.23.5.3 Equipment for New Construction===

'''Support.'''

:'''Cabinet.''' Develop plans with the ultimate number of FYA approaches accounted for. Install the cabinet with an appropriate number of load switches configured for full implementation of both left turn and right turn FYA. This may require a 16-position backpanel for locations with pedestrians and overlap movements.

:'''Controller and Conflict Monitor.''' Regardless if [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1092] requires FYA logic, including a footnote on the D-37C sheet to reinforce FYA logic is necessary for new controllers and conflict monitors.

:'''Signal Heads.''' Make sure FYA indications are noted on the intersection plan sheet and quantity included on D-37A sheet for those approaches where FYA will be installed on the project.

'''Support.'''
:'''Other Plan Items.''' On D37-D sheet, include notation on which indications are to be wired to FYA outputs. On D38-A sheet, make sure the FYA indications are included in the Phasing Sequence chart.

===902.23.5.4 Signal Hardware Purchases (Internal Retrofit)===

'''Support.''' If the decision has been made to upgrade an existing signal by MoDOT forces, then plenty of lead time must be given to have all of the needed equipment on hand and ready to install. The district might elect to utilize a private contractor to do all or some of the retrofit. Purchasing of the equipment and/or contractor services will be done through General Services with detailed information given on the following items:
{|style="padding: 0.3em; margin-left:15px; border:2px solid #a9a9a9; text-align:center; font-size: 95%; background:#f5f5f5" width="180px" align="right"
|-
|[[media: 902.11.28.3.6 D6 Contract Submittal Example.pdf|St. Louis District contract submittal example]]
|}

:* Quantity of items

:* Traffic Control Plan

:* Cabinet print numbers

:* Specify Commission furnished vs. contractor furnished items clearly (if any)

:* Completion date

:* Specific days and times of installation allowed due to local traffic conditions

:* Disposition of removed equipment

:* Signing

For a district’s first installation, it is advisable to acquire the upgraded controller and monitor a few weeks in advance of the installation date so in-depth bench testing can be done by all interested parties.

===902.23.5.5 Regional Cooperation===

'''Support.''' Installation of the FYA at another agency’s signals might not be possible. One of the critical requirements of this option is that each lane on the approach have its own signal head. The left turn signal head cannot be sharing its circular indications with the adjacent through lanes. If an agency does not use this type of control, they cannot use the FYA. If the adjacent agency’s signals are using positive lane control, then cooperation in the form of simultaneous FYA installations can be explored.
