Calibration and validation of TRANSIMS microsimulator for an urban arterial network
Abstract TRANSIMS, a travel demand modeling software package initially developed by the Los Alamos National Laboratory (LANL), enables modeling of individual activities and provides second-by-second simulation results on vehicular movements. TRANSIMS has been applied more than a decade, but calibration and validation of TRANSIMS Microsimulator have not received proper attention from transportation engineering community. This paper presents a case study of a TRANSIMS Microsimulator calibration and validation using an experimental design approach. An urban arterial network consisted of four signalized intersections was calibrated against field measured travel times and traffic count data. The distributions of travel times and traffic count obtained from the multiple replications of the default parameter values were not able to replicate field conditions, while the proposed approach did well. Even though this case study used a small corridor network in urban area, the calibration and validation procedure could be extended to a larger scale network in TRANSIMS modeling as well as transportation planning applications.
