The goals of this project are to produce a report of 2004-2008 Virginia Work-Zone Crash Facts as a stand-alone document and to develop a more robust set of work-zone safety performance measures for Virginia. The researchers will consider both program-level and project-level measures. All roads that VDOT administers will be included for the program-level measures. However, for the project-level measures, the scope is limited to interstate highways because of data availability.
