 Title: Work Zone Throughput Models for Southern Ontario Authors: Ahmadi, Bijan Advisor: McCabe, Brenda Department: Civil Engineering Keywords: Highway Work Zones, Lane Throughput, User Delay Issue Date: 1-Dec-2011 Abstract: Highway lane closures cause reductions in the traffic throughput which lead to premature queuing. To minimize user delays, contractors are required to keep highway lanes open during the peak traffic hours and work at nights. However, these limitations can reduce the quality of the work and extend project duration. Finding a right balance between the times that the lanes can be closed and the times they should be kept open can increase the efficiency of the contractors’ work. Over 100 hours of throughput data were collected in two phases from 2007 to 2010 from Southern Ontario highways. Using regression analysis, a generic and a highway specific model were developed predicting the mean throughput in approximately 50% of cases within one hundred vehicles per hour per lane of the actual mean. Also the Simplified Work Zone User Delay Analysis model, developed in Phase 1, was refined to investigate the resulting queues. URI: http://hdl.handle.net/1807/30150 Appears in Collections: Master
