Book excerpt: Historically, the Ohio Department of Transportation (ODOT) has used QUEWZ to estimate road capacities for proposed lane closures which fall outside of the Permitted Lane Closure Map, as per Policy No. 21-008(P). The resulting capacity is included in the process for predicting queue lengths outlined in Section 640-13.2 of ODOT's Traffic Engineering Manual. QUEWZ is also identified in ODOT's Innovative Contracting Manual to estimate the capacities for calculating road user costs. The current problem is that QUEWZ is not compatible with current versions of Windows and no longer supported by the developer. Therefore, ODOT needs a replacement for QUEWZ. A new queue analysis tool was developed to meet the needs of the ODOT District Work Zone Traffic Managers for conducting queue length analyses. It is based on the 2010 Highway Capacity Manual capacity formulation for short term work zones and estimates the size and length of the queue and the associated delay for up to 24, 1 hour time intervals. A new road user cost tool was also developed, which calculates the travel costs, operating costs and crash costs of roadway construction projects, suitable for establishing monetary incentives for innovative contracting methods. These tools replace the use of QUEWZ and two existing ODOT spreadsheets.
