Design/Build versus Traditional Construction User Delay Modeling: An Evaluation of the Cost Effectiveness of Innovative Construction Methods for New Construction. Part 1. I-15 Reconstruction in Davis County. Evaluation of Various Traffic Maintenance P

摘要

This paper evaluates impact of various I-15 reconstruction closure scenarios on the travelers in Ogden area. The purpose of the research was to investigate impact of the scenarios and facilitate decision about future maintenance of traffic during the reconstruction. The original Wasatch Front Regional Council (WFRC) transportation planning model was converted from the TP+ software to the VISUM software. The VISUM model of the whole WFRC area was then calibrated and validated. Coefficient of determination between modeled and observed traffic volumes was 0.78. The model was then reduced, by partial network generation process in VISIM, to the Ogden area. Another set of calibration and validation was performed. The coefficient of determination has improved to 0.88. Twenty one reconstruction closure scenarios were developed in consultation with UDOT project managers. Traffic assignments were executed for each scenario for five diurnal periods.
