California MUTCD 2014 Edition Page 1133 <br />(FHWA's MUTCD 2009 Edition, including Revisions 1 & 2, as amended for use in California) <br />CHAPTER 6H. TYPICAL APPLICATIONS <br />Section 611.01 Tvpical Applications <br />Support: <br />or Chapter 6G contains discussions of typical TTC activities. This Chapter presents typical applications for a <br />variety of situations commonly encountered. While not every situation is addressed, the information illustrated <br />can generally be adapted to a broad range of conditions. In many instances, an appropriate TTC plan is achieved <br />by combining features from various typical applications. For example, work at an intersection might present a <br />near -side work zone for one street and a far -side work zone for the other street. These treatments are found in two <br />different typical applications, while a third typical application shows how to handle pedestrian crosswalk <br />closures. For convenience in using the typical application diagrams, Tables 6C-1 and 6C-4 are reproduced in this <br />Chapter as Tables 611-3 and 611-4, respectively. <br />02 Procedures for establishing TTC zones vary with such conditions as road configuration, location of the work, <br />work activity, duration of work, road user volumes, road vehicle mix (buses, trucks, cars, motorcycles, and <br />bicycles), and road user speeds. <br />03 In general, the procedures illustrated represent minimum solutions for the situations depicted. Except for the <br />notes (which are clearly classified using headings as being Standard, Guidance, Option, or Support), the <br />information presented in the typical applications can generally be regarded as Guidance. <br />Option: <br />04 Other devices may be added to supplement the devices and device spacing may be adjusted to provide <br />additional reaction time or delineation. Fewer devices may be used based on field conditions. <br />Support: <br />os Figures and tables found throughout Part 6 provide information for the development of TTC plans. Also, <br />Table 611-3 is used for the determination of sign spacing and other dimensions for various area and roadway <br />types. <br />06 Table 611-1 is an index of the 46 typical applications. Typical applications are shown on the right-hand page <br />with notes on the facing page to the left. The legend for the symbols used in the typical applications is provided <br />in Table 611-2. In many of the typical applications, sign spacings and other dimensions are indicated by letters <br />using the criteria provided in Table 611-3. The formulas for determining taper lengths are provided in Table 611-4. <br />m Most of the typical applications show TTC devices for only one direction. <br />Guidance. <br />oe The spacing of channelizing devices should not exceed the maximum distances shown in Table 6F-101(CA). <br />Chapter 6H — Typical Applications November 7, 2014 <br />Part 6 —Temporary Traffic Control <br />
