Evaluation of Work Zone Software Programs: Phase 2 - Validation Using Field Data

项目名称：	Evaluation of Work Zone Software Programs: Phase 2 - Validation Using Field Data
摘要：	In 2008, the University of Missouri evaluated several software programs for work zone traffic impact analysis and identified appropriate analytical tools for assessing traffic impacts at different types of work zones. This research was funded by the Missouri Department of Transportation (MoDOT). Three software programs - QuickZone, VISSIM, and CA4PRS were evaluated, and a customized spreadsheet for Missouri conditions, Work Zone (WZ) Spreadsheet, was developed. WZ Spreadsheet produces queue length and delay estimates with minimum amount of input data. The current project is aimed at calibrating and validating the software programs using real world data. Performance measures such as queue length and delay obtained from the programs will be compared with the values observed in the field. The accuracy of results produced by each program will be quantified so that the users can attribute a level of confidence to the program's outputs. Thus the software programs will be calibrated to provide reliable and documented results so as to improve traffic operations and safety in work zones.
