Abstract:The Missouri Department of Transportation (MoDOT) is looking for software tools that can assist in developing effective plans to manage and communicate work zone activities. QuickZone, CA4PRS, VISSIM, and Spreadsheet models are the tools that MoDOT is particularly interested in. These tools quantify the travel delays and hence can be used to plan, design, and schedule the work activity so as to minimize those delays. In this report, the findings of a research project on evaluating the four identified work zone tools are presented. Based on the results of a literature review, state DOT survey, and case studies conducted in this project, recommendations were made for the most appropriate tool for different work zone configurations. The study recommendations are: 1) For rural interstates, divided roadways, and multilane undivided highways in Missouri the Spreadsheet model developed in this study should be used, 2) For work zones in urban areas where lane closures on a roadway may impact the traffic on neighboring roadways, the use of VISSIM is recommended. It is also suggested that the driver behavior parameters in VISSIM be selected from the calibration charts developed in this study to obtain field capacity values, 3) For a two way one lane work zone with flagger operation, Quick Zone and VISSIM are recommended.
