==616.8.1 Temporary Traffic Control for Contract Plan Sheet Development==
=={{SpanID|616.16.1}}616.16.1 Typical Applications (MUTCD Section 6P.01)==
'''Support. '''[[616.14 Types of Temporary Traffic Control Zone Activities (MUTCD Chapter 6N)#616.14|EPG 616.14]] contains discussions of typical TTC activities.  [[616.1 General (MUTCD Chapter 6A)#616.1.2|EPG 616.1.2]] contains discussions on development of TTC plans for the various activities. This article presents typical applications for a variety of situations commonly encountered. While not every situation is addressed, the information illustrated can generally be adapted to a broad range of conditions. In many instances, an appropriate TTC plan is achieved by combining features from various typical applications. For example, work at an intersection might present a near-side TTC zone for one street and a far-side TTC zone for the other street. These treatments are found in two different typical applications in the MUTCD, while a third typical application shows how to handle pedestrian crosswalk closures.


Each work zone is different and requires different temporary traffic control (TTC) plans.  For contract plan sheets, [https://mutcd.fhwa.dot.gov/pdfs/2009r1r2r3/pdf_index.htm MUTCD (2009) Chapter 6H] provides the typical applications (TAs) to develop TTC plans and for in-field modifications as directed by the engineer.  TAs should be altered, when needed, to fit the conditions of the specific work zone.  See [[:Category:237_Contract_Plans|EPG 237]] for additional plan sheet guidance.
In general, the procedures illustrated represent minimum solutions for the situations depicted. Except for the notes (which are clearly classified using headings as being Standard, Guidance, Option, or Support), the information presented in the MUTCD typical applications can generally be regarded as Guidance.


References to work vehicle or shadow vehicle made in the MUTCD will be considered incidental and should be indicated as such on the TTC plans.
'''Option'''. TTC plans may deviate from the typical applications described in this article to allow for conditions and requirements of a particular site or jurisdiction.  


When optional items are referenced in the MUTCD, the contractor may, at their discretion, utilize the items as incidental. When the TTC plans indicate one or more of these items as required for stationary work activities, applicable pay items will apply and will be included. Field adjustments, as directed by the engineer, may require additional pay items via a change order. When use of a Truck Mounted Attenuator (TMA) is deemed necessary for one or more stationary work activities, this will be indicated on the TTC plans, the Truck Mounted Attenuator (TMA) for Stationary Work Activities JSP will be included in the contract, and the Truck Mounted Attenuator pay item will be provided.
Other devices may be added to supplement the devices and device spacing may be adjusted to provide additional reaction time or delineation. Fewer devices may be used based on field conditions.


TMAs used in mobile operations, such as striping, are considered incidental per Sec 612.5.
'''Support'''. Figures and tables found throughout EPG 616 provide information for the development of TTC plans.

'''Guidance. '''For contract projects, the typical applications in Chapter 6P of the [https://mutcd.fhwa.dot.gov/kno_11th_Edition.htm MUTCD] should be the basis for preparing TTC plans. The MUTCD typical applications themselves are not provided in the EPG, but are included in the EPG by reference.

'''Support. '''Table 6P-1 of the MUTCD is an index of the 54 typical applications. In the printed version of the MUTCD, the typical applications are shown on the right-hand page with notes on the facing page to the left. In the electronic version, the notes are shown on the page preceding the figure. The legend for the symbols used in the typical applications is provided in Table 6P-2 of the MUTCD. In many of the typical applications, sign spacings and other dimensions are indicated by letters using the criteria provided in [[616.2 Temporary Traffic Control Elements (MUTCD Chapter 6B)#tab616.2.4|Table 616.2.4]]. The formulas for determining taper lengths are provided in [[616.2 Temporary Traffic Control Elements (MUTCD Chapter 6B)#tab616.2.8.2|Table 616.2.8.2]].

These TAs are intended for the use of MoDOT employees. Before each work shift, all employees are required to participate in a pre-shift safety briefing.  During the briefing, the applicable TAs should be printed out and then discussed to know the procedures to follow for the day’s work. This should include the risk-based assessment (RBA). The TAs shown in the EPG are considered current.
Most of the typical applications show TTC devices for only one direction.

616.16.1 Typical Applications (MUTCD Section 6P.01)

Support. EPG 616.14 contains discussions of typical TTC activities. EPG 616.1.2 contains discussions on development of TTC plans for the various activities. This article presents typical applications for a variety of situations commonly encountered. While not every situation is addressed, the information illustrated can generally be adapted to a broad range of conditions. In many instances, an appropriate TTC plan is achieved by combining features from various typical applications. For example, work at an intersection might present a near-side TTC zone for one street and a far-side TTC zone for the other street. These treatments are found in two different typical applications in the MUTCD, while a third typical application shows how to handle pedestrian crosswalk closures.

In general, the procedures illustrated represent minimum solutions for the situations depicted. Except for the notes (which are clearly classified using headings as being Standard, Guidance, Option, or Support), the information presented in the MUTCD typical applications can generally be regarded as Guidance.

Option. TTC plans may deviate from the typical applications described in this article to allow for conditions and requirements of a particular site or jurisdiction.

Other devices may be added to supplement the devices and device spacing may be adjusted to provide additional reaction time or delineation. Fewer devices may be used based on field conditions.

Support. Figures and tables found throughout EPG 616 provide information for the development of TTC plans.

616.16.2 Typical Applications for Contract Projects

Guidance. For contract projects, the typical applications in Chapter 6P of the MUTCD should be the basis for preparing TTC plans. The MUTCD typical applications themselves are not provided in the EPG, but are included in the EPG by reference.

Support. Table 6P-1 of the MUTCD is an index of the 54 typical applications. In the printed version of the MUTCD, the typical applications are shown on the right-hand page with notes on the facing page to the left. In the electronic version, the notes are shown on the page preceding the figure. The legend for the symbols used in the typical applications is provided in Table 6P-2 of the MUTCD. In many of the typical applications, sign spacings and other dimensions are indicated by letters using the criteria provided in Table 616.2.4. The formulas for determining taper lengths are provided in Table 616.2.8.2.

Most of the typical applications show TTC devices for only one direction.
