Auditing Work Zone Mobility Using Probe Vehicle Data

This document aims to introduce the concept of a Work Zone Mobility Audit and define the involved data for completing such an audit. Agencies have a difficult time assessing the operational performance of work zones. The document will share a brief history of work zone performance measures before discussing how to use scalable crowd sourced probe vehicle data to assess the performance of work zones.

Section 1 of this document covers the background of work zone performance measures including examples of data, performance measures, and performance thresholds. The section also introduces existing tools that agencies are using to assess work zone mobility.

Section 2 of this document introduces the concept of a work zone mobility audit and discusses options for agencies to complete these audits. The section introduces the work zone mobility audit template that was automated by Wayne State University. The section concludes by explaining the performance measures utilized in the audit.

Section 3 of this document introduces the work zone mobility audit template and tool developed by the Wayne State University Transportation Research Group. Case studies are presented and future applications are discussed. The section concludes by discussing the organizational capabilities to use the tool.
