Highway signs are directly related to the design of the highway and effectively provide travelers with information needed to safely and efficiently complete trips.  Signs must have uniformity of meaning.  Excessive and inadequate signing can cause traveler confusion.

This article outlines procedures for the preparation of contract signing plans.  Before beginning sign selection or location, the following are to be reviewed:  this article, the guidelines of the MUTCD and FHWA's ''Standard Highway Signs'' manual.  It is important to use standard sign design and layouts in order to provide consistent signing throughout the state of Missouri.  The districts are responsible for proper review of signing plans for accuracy, to ensure standards are met and deviations from the standards are justified.
 
  
The need for uniform standards was recognized long ago. The American Association of State Highway Officials (AASHO), now known as the American Association of State Highway and Transportation Officials (AASHTO), published a manual for rural highways in 1927, and the National Conference on Street and Highway Safety (NCSHS) published a manual for urban streets in 1930. In the early years, the necessity for unification of the standards applicable to the different classes of road and street systems was obvious. To meet this need, a joint committee of AASHO and NCSHS developed and published the original edition of the ''MUTCD'' in 1935. That committee, now called the National Committee on Uniform Traffic Control Devices (NCUTCD), though changed from time to time in name, organization, and personnel, has been in continuous existence and has contributed to periodic revisions of this article. The FHWA has administered [http://mutcd.fhwa.dot.gov/index.htm the ''MUTCD''] since the 1971 edition.  The FHWA and its predecessor organizations have participated in the development and publishing of the previous editions.  There were eight previous editions of the ''MUTCD'', and several of those editions were revised one or more times.

'''History.'''  The need for uniform standards was recognized long ago. The American Association of State Highway Officials (AASHO), now known as the American Association of State Highway and Transportation Officials (AASHTO), published a manual for rural highways in 1927, and the National Conference on Street and Highway Safety (NCSHS) published a manual for urban streets in 1930. In the early years, the necessity for unification of the standards applicable to the different classes of road and street systems was obvious.

The FHWA has administered [http://mutcd.fhwa.dot.gov/index.htm the ''MUTCD''] since the 1971 edition and is the sole authority over its content since that time.  
  
The U.S. Secretary of Transportation, under authority granted by the Highway Safety Act of 1966, decreed that traffic control devices on all streets and highways open to public travel in accordance with 23 U.S.C. 109(d) and 402(a) in each state shall be in substantial conformance with the Standards issued or endorsed by the FHWA.

The U.S. Secretary of Transportation, under authority granted by the Highway Safety Act of 1966, decreed that traffic control devices on all streets and highways open to public travel in accordance with 23 U.S.C. 109(d) and 402(a) in each state shall be in substantial conformance with the Standards issued or endorsed by the FHWA.23 CFR 655.603, which adopts the MUTCD as the national standard for any street, highway, or bicycle trail open to public travel in accordance with 23 U.S.C. 109(d) and 402(a).
  
23 CFR 655.603 adopts the ''MUTCD'' as the national standard for any street, highway, or bicycle trail open to public travel in accordance with 23 U.S.C. 109(d) and 402(a). The “Uniform Vehicle Code (UVC)” is one of the publications referenced in the ''MUTCD''. The UVC contains a model set of motor vehicle codes and traffic laws for use throughout the United States. States are encouraged to adopt Section 15-116 of the UVC that states, “No person shall install or maintain in any area of private property used by the public any sign, signal, marking, or other device intended to regulate, warn, or guide traffic unless it conforms with the State manual and specifications adopted under Section 15-104.”

'''Support.'''  Missouri Revised Statue 300.135 states ''“All traffic control signs, signals and devices shall conform to the manual and specifications approved by the state highways and transportation commission or resolution adopted by the legislative body of the city. All signs or signals required hereunder for a particular purpose shall so far as practicable be uniform as to type and location throughout the city. All traffic control devices so erected and not inconsistent with the provisions of this ordinance shall be official traffic control devices.” ''

The standards, guidance, options and support material described in this article provide the transportation professional with the information needed to make appropriate decisions regarding the use of traffic control devices on streets and highways.  The material in this edition provides standards that must be satisfied for the particular circumstances of a situation, guidance that is to be followed for the particular circumstances of a situation and options that may be applicable for the particular circumstances of a situation.

September 12, 1961, the Commission first adopted the provisions of the ''Manual on Uniform Traffic Control Devices'' (MUTCD) and authorized the department staff to bring signing, marking, and signalization on the State Highway System into conformity therewithOn July 10, 2001, the Commission approved the most current version of the MUTCD as the basis for MODOT traffic control policy into the future and authorized implementation of actions need to bring future deviations into compliance.  
 
 
Except when a specific numeral is required by an EPG 903 Highway Signing article, numerals shown on the sign images in the figures that specify quantities such as times, distances, speed limits and weights should be regarded as examples only.  When installing any of these signs, the numerals should be appropriately altered to fit the specific signing situation.
 
 
 
The preliminary layouts of all signs included in the project, along with a completed [[media:D-28.doc|Sign Design Order Form (Design Form D-28)]], shall be provided to Traffic so that 30 working days are allowed for review and design to be completed.  Each sign shall be identified as an [[903.4 Overhead Guide Sign Mounting|overhead]] or [[903.3 Post-Mounted Signing|post-mounted]] sign.  [http://wwwi/intranet/tr/ Traffic] shall be provided with a date the sign designs need to be returned for review.  The return date needs to allow enough time to design and quantify the bases and trusses or posts.

'''THE INTERSTATE SYSTEM.''' Signing of all interstate highways is coordinated on a national basis by [http://mutcd.fhwa.dot.gov/index.htm the ''MUTCD''] and Standard Highway Signs.
 
 
 
'''OTHER HIGHWAYS.'''  Signing of highways other than the interstate system is coordinated on a statewide basis by MoDOT and the ''MUTCD''.
 
 
 
==MoDOT 5-Year Plan for Signing – Practical Operations==
 
 
 
Highway signing was identified as one of the major cost drivers in MoDOT operations and was extensively evaluated to identify ways to reduce cost and waste while maintaining our signs in good condition.  Cost-saving strategies involve manufacturing, shipping, warehousing, installing and the signs' materials.
 
 
 
It was determined the MoDOT Sign Production Center (SPC) should discontinue the fabrication of any product that did not relate directly to the roadways or support a key MoDOT operation.  This change in direction was required to allow the SPC to dramatically cut its operating budget without compromising its ability to provide quality highway signing.
 
 
 
'''Guidance for managing sign material inventories'''
 
 
 
* Typically only 2 to 3 of each [http://epg.modot.org/index.php?title=903.2_Ground-Mounted_Signing#Table_903.2.22_Incident_Response_Plan_-_Signing priority one sign] and their posts shall be maintained at any given building.  Usage history should be used to determine the appropriate number for each location.
 
 
 
* The majority of sign and post inventories need to be located at a centralized distribution point, typically the district sign shop or district warehouse.  Post and signs can be picked up from a central location to complete work orders.  Centralizing resources makes it easier to manage the inventory for the district and reduces the on hand inventory significantly.
 
 
 
* Before a sign or post is ordered as a new product, the district inventory must first be checked to determine if those materials exist in stockIf the materials are not in stock and the need is urgent, attempts should be made to locate those materials in the inventories of the neighboring districts before placing a rush order for fabrication.
 
 
 
* Other than knock downs and damage repair, sign work should be planned in advance.  Signs and other materials should be ordered at a rate that matches the capacity to install the signs to avoid inventory buildup.  While signs acquired for specific purposes may not truly be “inventory”, they do represent resources that are not being used unless they are installed.  The likelihood of signs becoming damaged or misplaced, increase with long term storage and also places an undue demand on the district warehouse and SPC.
 
 
 
* Communication between those who install, warehouse and manufacture the signs as well as between other districts is critical to minimize waste and ensure the materials are on hand when they are needed.
 
 
 
* If excess material in usable condition is located in a district, it should be made known and available to the other districts so it can be utilized. '''[http://ghdata022/ghq_public/Traffic/Available Excess Sign Material Inventory/Available Excess Sign Material Inventory.xlsx] The Electronic Bulletin Board''' has been developed to allow districts to post and look for excess materials that are available from other districts.
 
 
 
* It is critical when signs are removed from a roadway that they be transported in a timely manner to the Moberly Correctional Facility where they can be used to make new signs.  Handling structural panels correctly is especially critical as they cannot be repaired like flat sheet signs.  Structural signs should be remove from the post and disassembled, removing all post clamps and taking panels apart.  The panels should be nested together for transport to keep them straight and undamaged.  The SPC’s ability to utilize reclaimed materials dramatically reduces production costs as well as speeds up production.  Reclaimed sign panels are 70% cheaper than new and the prison can supply reclaimed sign material faster than the vendors who supply new signs panels. It is to be emphasized that:
 
::: Incorrectly stored and transported signs result in damaged and unusable panels,
 
::: Correctly disassembled structural signs will ensure maximum reclamation and
 
::: Extruded panels damaged beyond use do not need to be sent to reclamation facility.  
 
 
 
Practical Operations for signing also re-evaluates signing practices.  A number of signs have been identified as ”unnecessary” or “limited use”, as compared to MoDOT’s current application processes.  Guidance has been updated to reflect these changes for:

'''Standard.'''  The traffic control articles of the Engineering Policy Guide (EPG) serve as MoDOT’s Manual on Uniform Traffic Control DevicesThe EPG shall be used when applying traffic control devices to state maintained routes.  The MUTCD cannot be used as a standalone document without the EPG when applying traffic control devices to state maintained routes as MoDOT does not adopt all options found in the MUTCD as many do not apply.  In addition, MoDOT’s standards for the application of traffic control devices may exceed the MUTCD minimums and therefore not referencing the EPG as the primary guidance can result in substandard applications on state maintained routesAny variations from the EPG guidance for traffic control devices shall be approved by the State Highway Safety and Traffic Engineer.

Other signs that have been identified as unnecessary or to have limited use, but do not currently have EPG guidance, are:
 
 
 
:1. <u>Center for Developmentally Disabled</u> – no new signs will be fabricated and existing signs will remain in place until the sign reaches the end of its life cycle.
 
 
 
:2. <u>Interstate Route Conformation Route Shields</u>  – With the implementation of the Emergency Reference Markers on interstates that display the route shield, it has been determined that the normal confirmation route marker installed following each on-ramp to an interstate is no longer needed.  Existing signs will remain in place until the end of their life cycle.
 
 
 
:3. <u>Outlet Mall Signing</u> – Signs to malls and outlet malls have been installed in the past to facilitate traffic management.  Locations where these management issues no longer exist should have these references removed at the end of the sign life cycle.
 
 
 
:4. <u>Outer Road Signs</u> – Outer road signing was installed as a form of route marking.  The US Postal Service for mailing addresses along these routes utilized the outer road designation.  Local jurisdictions are commonly placing street names over the outer roads for 911 purposes and to simply for local recognition.  When this occurs, the mailing addresses typically change and refer to the street name.  Once this occurs, our outer road signing is no longer required and the signs can be removed once they reach the end of their life cycle.
 
 
 
:5. <u>Amtrak Web Address Signs</u> - In an attempt to promote Missouri Rail service, [http://wwwi/intranet/mo/ Multimodal Operations] requested the installation of Amtrak Rail Service signs with a web address.  These signs will be removed at the end of their life cycle.
 
 
 
:6. <u>Tune Radio To…</u> - There have been locations where signs instruct motorists to turn their radio to a particular station to receive local information.  These signs will be removed at the end of their life cycle or at the end of their contract should there be one.  If the District Engineer determines that this information is critical for the motorist the signs can be remanufactured, however, the sponsor of the signs will be required to enter into a [http://epg.modot.mo.gov/index.php?title=903.2_Ground-Mounted_Signing#903.2.16_Signing_Paid_for_by_Others_.28MUTCD_Section_2A.21b.29 TR-15 contract] and be held responsible for the associated cost to install and maintain the sign.
 
 
 
:7. <u>Employee Name Signs</u> - In the past, the names of the Resident Engineers, Area Engineers and Maintenance Superintendants have been displayed outside of MoDOT project offices.  Every time a position was vacated and filled the signs were remade with the new name of the individual.  This signing will be discontinued and existing signs removed when they reach the end of their life cycle.
 
 
 
:8. <u>The Steer It / Clear It</u> – These signs were developed to help educate the public of the new law.  These signs will be removed once they reach the end of their life cycle.  Signs may remain or be installed at specific locations if the District Engineer determines their presence is critical for traffic management.
 
 
 
:9. <u>Medical Helipad Signs</u> – These signs provide no informational or safety benefit to the traveling public.  Existing signs will be removed at the end of their life cycle and no new signs installed.
 
 
 
MoDOT is required to meet federal minimum design criteria.  In some cases our standards meet those minimums while others exceed them.  Cases where our standards exceed the minimums were primarily due to older driver considerations and sign design consistency across the state. 
 
 
 
However, with the 5-year plan, sign design will be looked at more closely to maximize legibility and minimize cost.  When signs come up for replacement, the installation will be reviewed to determine what the federal minimums are.  If the existing sign meets the minimums it will be replaced in kind; if it falls below the minimums it will be upgraded.  In cases where the existing sign exceeds the minimums the sign will typically be replaced in kind to eliminate the need to replace the posts and footings to accommodate a smaller sign.  In all cases, if a deficiency is identified in the safety aspects of the sign installation, those issues must be corrected.  If sign design changes (i.e., changes in legend and/or route shields) are required, the sign will be designed to meet standards regardless of the condition of the posts.  These changes will require additional information to be submitted with the sign request, such as post size and spacing, to assure the new signs will fit the existing posts and that the installation meets safety criteria.  The [[media:903 Post Spacing Field Sheet.xls|Post Spacing Field Sheet]] worksheet is available.
 
 
 
Post selection will also be a factor in this initiativeWhile there are overlaps in capacities from one post type to another, all efforts should be made to utilize the most cost effective type of post for the given installation and application.  Wood posts are going to be strongly recommended for all two-lane roadways 400 AADT or below and a recommended product for all other two-lane  roadways.  However, based on soil conditions, environment, crew and equipment composition or other factors, the District Engineers may choose to utilize PSST instead of wood if they can provide evidence that PSST is more cost effective than wood. The [[Media:903.2a Signpost Selection Guide.xls|Signpost Selection Guide]] is presented in [[903.3 Post-Mounted Signing|EPG 903.3 Post-Mounted Signing]].
 
 
 
To ensure signs are in good condition and meet minimum retroreflectivity requirements, annual nighttime sign inspections will be conducted each year.  These inspections determine whether the sign’s retroreflectivity levels are sufficient, whether the sign is present, plumb and in good condition.  Daytime inspections are a good supplemental practice to help identify issues that cannot bee seen at night, such as incorrect or missing breakaway devices.  Signs that meet expectations will not be replaced.  The Maintenance performance indicator criteria for acceptable in the plumbness category has been revised to allow for 1 in. per ft. instead of ¼ in. per foot.  Sign inspectors must be trained to identify what constitutes a good sign and when a sign falls below acceptable levels.  The following outlines how signs are to be evaluated in order to meet quality sign installations until a formal training can be developed.

: Signs made of steel, non-extruded panel structural signs, or wood substrate and signs made with engineer grade sheeting and button copy should be replaced due to age.
 
::<u>Flat Sheet Signs</u>
 
::Signs must be visible and legible from approximately 300 ft. (based on Note 1 in [[903.6 Warning Signs#Table 903.6.6 Guidelines for Advance Placement of Warning Sign|Table 903.6.6 Guidelines for Advance Placement of Warning Sign]]).  Signs not visible at this distance due to:
 
:::* Obscured by vegetation: trim the vegetation
 
:::* Low or no retroreflectivity: replace the sign
 
:::* Paintballs, gun shots or other vandalism: replace the sign
 
  
::<u>Structural Signs (Extruded Panel Substrate)</u>
 
::Signs must be visible and legible from a minimum ofapproximately 300 ft. on two-lane roadways and 600 ft. on multilane highways (based on 30 ft. visibility for every 1 in. of legend height – EPG 903.2.24).  Signs not visible at these distances due to:
 
:::* Obscured by vegetation: trim the vegetation
 
:::* Low or no retroreflectivity: replace the sign
 
:::* Paintballs, gun shots or other vandalism: replace the sign

::<u>Signposts</u>
 
::* Posts that are visibly out of plumb from the driver’s seat to a degree that the general public would notice:  plumb or replace sign post.
 
::* Posts that are oriented in a fashion that they do not support the sign perpendicular to the roadway: repair or replace post to properly orient sign.
 
::* Wood posts that are twisted and/or warped that result in the sign not being held perpendicular to the travelway or properly oriented in a level position: replace post.
 
::* Short posts that fail to support signs 5 ft. above the driving surface on two-lane roadways and 7 ft. above roadway inside city limits or on freeways or expressways (does not include object markers, chevrons, supplemental plaques or any other special sign mounting criteria): modify or replace post to acquire proper mounting height.
 
::* Post that support signs properly above driving surface, but less than 5 ft. above ground at installation point need to be modified or replaced to acquire proper mounting height
 
::* Structural posts #3 through #6 that are closer than 7 ft. from one another (to meet federal breakaway standards): replace posts and footings.
 
  
::<u>Inspection Practices</u>
+
[[image:903 c.jpg|center|850px]]
::* Signs shall be inspected 1 hour after sunset and at least 1 hour prior to sunrise to ensure complete darkness
 
::* Signs shall be inspected with low beam headlights
 
::* Keep interior lights off so eyes are acclimated to darkness (dim lights are OK to illuminate computer keyboard)
 
::* Once frost and/or dew begin to settle on the signs (thus affecting retroreflectivity), discontinue inspections
 
::* Signs on side streets shall be inspected by driving the side street approaching the sign
 
::* The sign legend and background colors should be recognizable both day and night (for example, a [[903.4 Overhead Guide Sign Mounting|guide sign's]] white legend should be clearly visible and the background should be recognizable as green).  If not, replace the sign.
 
::* If inspection takes place after leaves have dropped and tree limbs fall within the view of the sign, but do not obscure sign: trim limbs to account for the time when leaves will regrow
 
::* Inspection vehicles should be typical cars, SUVs or pickups, 2002 or newer
 
::* Two-person inspection crews for safety
 
::* Inspection conducted from travel lane (not shoulder) and conducted at normal travel speed
 
::* Headlights should be cleaned before inspection begins. Clouded or hazed lenses should be polished
 
::* Headlights should be checked to ensure they are properly aimed

History. The need for uniform standards was recognized long ago. The American Association of State Highway Officials (AASHO), now known as the American Association of State Highway and Transportation Officials (AASHTO), published a manual for rural highways in 1927, and the National Conference on Street and Highway Safety (NCSHS) published a manual for urban streets in 1930. In the early years, the necessity for unification of the standards applicable to the different classes of road and street systems was obvious. To meet this need, a joint committee of AASHO and NCSHS developed and published the original edition of the MUTCD in 1935. That committee, now called the National Committee on Uniform Traffic Control Devices (NCUTCD), though changed from time to time in name, organization, and personnel, has been in continuous existence and contributes to the revisions of the MUTCD. The FHWA has administered the MUTCD since the 1971 edition and is the sole authority over its content since that time.

The U.S. Secretary of Transportation, under authority granted by the Highway Safety Act of 1966, decreed that traffic control devices on all streets and highways open to public travel in accordance with 23 U.S.C. 109(d) and 402(a) in each state shall be in substantial conformance with the Standards issued or endorsed by the FHWA.23 CFR 655.603, which adopts the MUTCD as the national standard for any street, highway, or bicycle trail open to public travel in accordance with 23 U.S.C. 109(d) and 402(a).

Support. Missouri Revised Statue 300.135 states “All traffic control signs, signals and devices shall conform to the manual and specifications approved by the state highways and transportation commission or resolution adopted by the legislative body of the city. All signs or signals required hereunder for a particular purpose shall so far as practicable be uniform as to type and location throughout the city. All traffic control devices so erected and not inconsistent with the provisions of this ordinance shall be official traffic control devices.”

September 12, 1961, the Commission first adopted the provisions of the Manual on Uniform Traffic Control Devices (MUTCD) and authorized the department staff to bring signing, marking, and signalization on the State Highway System into conformity therewith. On July 10, 2001, the Commission approved the most current version of the MUTCD as the basis for MODOT traffic control policy into the future and authorized implementation of actions need to bring future deviations into compliance.

Standard. The traffic control articles of the Engineering Policy Guide (EPG) serve as MoDOT’s Manual on Uniform Traffic Control Devices. The EPG shall be used when applying traffic control devices to state maintained routes. The MUTCD cannot be used as a standalone document without the EPG when applying traffic control devices to state maintained routes as MoDOT does not adopt all options found in the MUTCD as many do not apply. In addition, MoDOT’s standards for the application of traffic control devices may exceed the MUTCD minimums and therefore not referencing the EPG as the primary guidance can result in substandard applications on state maintained routes. Any variations from the EPG guidance for traffic control devices shall be approved by the State Highway Safety and Traffic Engineer.

Guidance. Like the MUTCD, the traffic control articles of the EPG are permissive guidance, meaning these articles outline what is permissible regarding applying traffic control devices to MoDOT roadways. When specific traffic control guidance is not found in the EPG to address a specific concern or application, the Highway Safety and Traffic Division should be contacted for assistance. The division office has access to additional resources, such as other MoDOT districts, FHWA, research facilities and other states, from which MUTCD compliant solutions can be sourced. If these solutions have the possibility of being applicable to more than one site, consideration will be made to include the solution into the EPG guidance.
