BEST PRACTICE:

D1−2: Corridor Planning to Minimize Delays and Enhance Safety in Work Zones

DESCRIPTION:

The Indiana Department of Transportation (INDOT) collects data on current traffic and determines the amount of traffic the road can carry while being reconstructed. They conduct an analysis on the likely routes to be used in the corridor by traffic that cannot be accommodated on roads under construction. Improvements are made on alternate routes as needed to have sufficient capacity.

REASON(S) FOR ADOPTING:

This practice of reviewing an entire corridor and upgrading its traffic carrying capacity, prior to beginning the heaviest construction, was implemented to improve safety and mobility.

PRIMARY BENEFIT(S):

Safety on the construction project is increased and motorist delay is decreased substantially. It has also helped to reduce the number of complaints received by INDOT about construction zone delays.

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

Normally applied to freeway and other high−volume arterials.

STATE(S) WHERE USED:

Indiana
