Estimating infrastructure impacts using ITS data and traffic simulation methods

The purpose of this paper is to outline a methodology in which Intelligent Transportation System (ITS) data, including weigh-in-motion (WIM) and automatic vehicle classification (AVC) data, are used to calibrate microscopic traffic simulation models and to provide accurate estimates of truck loadings and distributions for input to infrastructure models. The paper is divided into three primary sections. The first section outlines the ITS data sources available to calibrate microscopic traffic simulation models to account for the commercial motor vehicles (CMVs) in the traffic stream. The second section outlines an application of the methodology using the CORSIM microscopic traffic simulation model to develop distributions of CMVs for use in infrastructure analyses. The third section summarizes the results of the analysis and outlines the methodology in which the simulation output can be used to estimate infrastructure effects of CMVs using the results of the microscopic traffic simulation model. The results of this paper are expected to be useful to engineers and planners, particularly those involved with the planning and operation of heavy vehicle and freight facilities and infrastructure.
