BEST PRACTICE:

E2−2: Comparisons of the Estimated Construction Time Required to Maintain Traffic Versus Diverting Traffic

DESCRIPTION:

The Indiana Department of Transportation (INDOT) Design Manual calls for analyses to compare the benefits and costs, such as user costs, of traffic management options to determine the most appropriate option. This practice is covered under the transportation management plans component of the INDOT Design Manual. It is considered specifically when reviewing traffic control alternatives. The alternatives to analyze include on−site options (e.g., lane closures, use of shoulders) as well as detours. For on−site options, considerations include factors such as right−of−way costs, user delay costs, and accident potential. Analysis for detours includes factors such as additional travel time, the cost to travel the extra distance, the cost for any improvements needed to the detour route, and the effect of the detour on the community and local businesses. The manual provides guidance on identification of options and how to perform the calculations.

REASON(S) FOR ADOPTING:

To support the selection of effective traffic control alternatives.

PRIMARY BENEFIT(S):

The biggest benefit realized is easier construction for the contractor and increased safety of the traveling public, and it is usually cost effective.

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

This type of practice may be cost effective on various types of facilities. Each project is site specific.

STATE(S) WHERE USED:

Indiana
