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.
616.16.3 Typical Applications for MoDOT Internal Use
If you have questions about a Typical Application, please email WZTAQuestions@modot.mo.gov
Support. MoDOT has developed the following typical applications 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 typical applications 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 typical applications shown in the EPG are considered current.
