• Abstract:
  In this report, Texas Transportation Institute researchers identify key work zone safety and mobility ; performance measures that the Texas Department of Transportation (TxDOT) should target as part of a work ; zone monitoring program within a district, region, or across the state. Analysis methodologies and ; computational procedures are presented that will yield the recommended performance measures. For ; mobility-based measures, researchers recommend that TxDOT target the collection of queue length and ; travel time delay data caused by temporary lane closures, as the congestion and delays that result from those ; activities are the simplest to isolate and attribute to the work activities themselves. ; With regard to work zone safety monitoring, researchers developed procedures that aid a district or project ; engineer in determining which projects are most suitable for safety monitoring via a periodic review of crash ; statistics occurring before and during the project. Researchers developed graphs that indicate combinations ; of work zone length (or work zone segment length), average daily traffic, normal crash rate, and work zone ; phase or project direction that will most likely allow for reasonable inferences to be made regarding the ; relative level of safety being maintained within the project. Researchers also developed graphs to aid field or ; district personnel in quickly determining whether accident frequencies being experienced during a project are ; within, or above, tolerance limits for that type of project on that facility.
