Calibration and Validation of VISSIM for Urban Heterogeneous Traffic

Modelling of vehicular traffic is a challenging task for traffic engineers under heterogeneous traffic conditions in India. Heterogeneous traffic is characterized by the presence of a mix of vehicles with varying static and dynamic features, lack of lane discipline and varying composition resulting in a very complex behavior. Microsimulation is an effective tool to study and model heterogeneous traffic. VISSIM is a microscopic traffic simulation software that has gained worldwide recognition in traffic flow modelling. Efficient simulation of Indian heterogeneous traffic conditions requires modification of the default parameters representing various traffic conditions in VISSIM. The present study is an attempt to calibrate and validate midblock sections on a four lane divided urban arterial in VISSIM. The model thus developed is applied to simulate a midblock with a bus stop. The simulation models developed can aid in the quantification of the impacts of bus stops on traffic flow conditions. The effect of two typical types of bus stops observed on Indian cities, the curb side bus stop and a bus bay bus stop were studied. The variation of speed along the midblock stretch in the presence of a bus at the bus stop, effect of dwelling time, as well as arrival frequency of buses on capacity, were also studied in this work.
