Best Practice

BEST PRACTICE:

G4−12: Traffic Pacing Design

DESCRIPTION:

This method is used when roadway construction activities (e.g., placing bridge beams, overhead sign structures, etc.) are taking place in or above all lanes of the roadway, thus requiring traffic to be temporarily slowed rather than completely stopped. Traffic is paced at a safe speed (desirably not less than 20 mph on the Interstate) to provide a gap in traffic and allow the work activities to be performed. The pacing of traffic is controlled by pilot vehicles (i.e., law enforcement vehicles with blue lights flashing) driven by uniformed law enforcement personnel. Any on−ramps between the beginning point of the pacing area and the work area are blocked until the pilot vehicle has passed. The traffic control supervisor is stationed at the work area continuously throughout the pacing operation to ensure radio communication between all the police vehicles involved in the pacing operation and the contractor/project administrator. Advance signing warning motorists of the traffic pacing area is also provided.

REASON(S) FOR ADOPTING:

To increase safety and reduce the number of crashes caused by roadway construction activities by allowing traffic to continue moving at a reduced speed rather than coming to a complete stop. This method is much less expensive and more convenient than building detours.

PRIMARY BENEFIT(S):

Increased safety by reducing the risk of crashes due to stationary vehicles on the roadway and reduced project costs.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

High−volume/high−speed urban and rural freeways and other multi−lane access controlled facilities. Type of work: Overhead work (e.g., bridges and overhead signs, etc.) requiring total roadway closure.

STATE(S) WHERE USED:

Florida
