General

support:

When the normal function of the roadway is suspended, temporary
traffic control planning provides for continuity of the movement of
motor vehicle, bicycle, and pedestrian traffic; transit operations;
and access to property and utilities.

The primary function of  temporary traffic control is
tn provide for the safe and efficient movement of vehicles,
bicyclists, and pedestrians through or around temporary traffic
control zones while reasonably protecting workers and
equipment.

Of equal importance to the public traveling through the
temporary traffic control zone is the safety of workers performing
the many varied tasks within the-'work space. Temporary traffic
control zones present constantly changing conditions that are
unexpected by the road user. This creates an even higher degree of
vulnerability for the workers on or near the roadway (see Section
6D.02). At the same time, the temporary traffic control zone
provides for the efficient completion of whatever activity
interrupted the normal use of the roadway.

Consideration for road user safety, worker safety, and the
efficiency of road user flow is an integral element of every
temporary traffic control zone, from planning through completion. A
concurrent objective of the temporary traffic control is the
efficient construction and maintenance of the highway.

No one set of temporary traffic control devices can satisfy all
conditions for a given project. 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 temporary traffic control devices. The temporary
traffic control selected for each situation depends on type of
highway, road user conditions, duration of operation, physical
constraints, and the nearness of the work space to road users.

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. Such programs have been found to result in a significant
reduction in the number of road users traveling through the
temporary traffic zone, which reduces the possible number of
conflicts.
