![]() Fewer devices may be used based on field conditions.Ġ5 Figures and tables found throughout Part 6 provide information for the development of TTC plans. ![]() Except for the notes (which are clearly classified using headings as being Standard, Guidance, Option, or Support), the information presented in the typical applications can generally be regarded as Guidance.Ġ4 Other devices may be added to supplement the devices and device spacing may be adjusted to provide additional reaction time or delineation. For convenience in using the typical application diagrams, Tables 6C-1 and 6C-4 are reproduced in this Chapter as Tables 6H-3 and 6H-4, respectively.Ġ2 Procedures for establishing TTC zones vary with such conditions as road configuration, location of the work, work activity, duration of work, road user volumes, road vehicle mix (buses, trucks, cars, motorcycles, and bicycles), and road user speeds.Ġ3 In general, the procedures illustrated represent minimum solutions for the situations depicted. These treatments are found in two different typical applications, while a third typical application shows how to handle pedestrian crosswalk closures. For example, work at an intersection might present a near-side work zone for one street and a far-side work zone for the other street. In many instances, an appropriate TTC plan is achieved by combining features from various typical applications. While not every situation is addressed, the information illustrated can generally be adapted to a broad range of conditions. This Chapter presents typical applications for a variety of situations commonly encountered. Typical Applications Section 6H.01 Typical ApplicationsĠ1 Chapter 6G contains discussions of typical TTC activities.
