GENERAL Section General Support: 1 Whenever the acronym TTC is used in part 6, it refers to TEMPORARY TRAFFIC CONTROL . Standard: 2 The needs and CONTROL of all road users (motorists, bicyclists, and pedestrians within the highway, or on private roads open to public travel (see definition in Section ), including persons with disabilities in accordance with the Americans with Disabilities Act of 1990 (ADA), Title II, Paragraph ) through a TTC zone shall be an essential part of highway construction, utility work, maintenance operations, and the management of TRAFFIC incidents.

8 Support: 3 When the normal function of the roadway, or a private road open to public travel, is suspended, TTC planning provides for continuity of the movement of motor vehicle, bicycle, and pedestrian TRAFFIC (including accessible passage); transit operations; and access (and accessibility) to property and utilities. 4 The primary function of TTC is to provide for the reasonably safe and effective movement of road users through or around TTC zones while reasonably protecting road users, workers, responders to TRAFFIC incidents, and equipment. 5 Of equal importance to the public traveling through the TTC zone is the safety of workers performing the many varied tasks within the work space.

9 TTC zones present constantly changing conditions that are unexpected by the road user. This creates an even higher degree of vulnerability for the workers and incident management responders on or near the roadway (see Section ). At the same time, the TTC zone provides for the efficient completion of whatever activity interrupted the normal use of the roadway. 6 Consideration for road user safety, worker and responder safety, and the efficiency of road user flow is an integral element of every TTC zone, from planning through completion. A concurrent objective of the TTC is the efficient construction and maintenance of the highway and the efficient resolution of TRAFFIC incidents.

10 7 No one set of TTC devices can satisfy all conditions for a given project or incident. At the same time, defining details that would be adequate to cover all applications is not practical. Instead, part 6 displays typical applications that depict common applications of TTC devices. The TTC selected for each situation depends on type of highway, road user conditions, duration of operation, physical constraints, and the nearness of the work space or incident management activity to road users. 8 Improved road user performance might be realized through a well-prepared public relations effort that covers the nature of the work, the time and duration of its execution, the anticipated effects upon road users, and possible alternate routes and modes of travel.
