Abstract:
"The Federal Highway Administration has been encouraging states to improve their monitoring and tracking of the

mobility impacts of work zones. The use of mobility performance measures will enable agencies to assess better the

contribution of work zones to network congestion; to identify specific projects that are in need of remedial action; and

potentially to assess penalties to contractors creating excessive, avoidable negative impacts. Although the Virginia Department

of Transportation (VDOT) has defined allowable lane closure hours for the interstate system, VDOT has not defined specific

performance measures and thresholds for what constitutes “unacceptable” work zone mobility impacts. Performance measures

and thresholds have been developed by a number of other states, so there is a need to determine whether these could be adapted

for use by VDOT.

This study explored issues related to a potential work zone mobility performance measurement program for Virginia.

The issues investigated included identification of potential performance measures, definition of performance thresholds, and

recommendations for data sources for performance measurement calculations. This information was synthesized from

information regarding the experiences of selected states and experiences from a series of case studies that used data from

Virginia work zones. The review of experiences in selected other states found that delay and queue length were the performance

measures used most often by the states studied. The Virginia case studies focused on the use of private sector data to generate

mobility performance measures and found that the level of spatial aggregation in rural areas could inhibit the ability to generate

accurate performance measures, although granularity was better on urban roads. The level of temporal aggregation was also

found to influence performance measures.

The research identified a number of key issues that VDOT should consider as a work zone mobility performance

measures program is developed. The report recommends that VDOT develop a pilot program that focuses on urban interstates

initially and convene a task group to develop formal policies and procedures for use in the state."
