Traffic flow modeling using micro-simulation approaches facilitate the study of bottlenecks and assists in the analysis of traffic flow characteristics, the movement of individual vehicles, and the study of vehicle and driver characteristics. In this context, simulation-based approaches are found to be more effective in modeling the traffic flow on roads.
Traffic engineers and transport planners often resort to traffic flow modeling techniques in order to evolve strategies for effective transport management. In developing economies, the heterogeneous mix of slow and fast-moving vehicles have further contributed to the chaos resulting in roads operating below existing capacities. IntroductionĬongestion and traffic delays in urban road networks have become a characteristic feature of present cities. The second-level of calibrations were performed by fine-tuning these three characteristics in three stages and the final VISSIM model was validated. An ANN-based sensitivity analysis was performed to find the relative importance of vehicle and driver characteristics, which revealed that the average standstill distance, minimum look-ahead distance, and the desired speed: lower bounds for speed distributions were highly sensitive. The accuracy of predicting simulated volumes was measured using GEH-statistic.
The multi-stage first-level of calibrations were performed starting with default values of vehicle and driver characteristics followed by testing of various combinations. The present study focuses on performing investigations on assessing the influence of vehicle and driver characteristics on accurate prediction of traffic volumes in Mangalore city road network. Traffic-flow modeling using microsimulation approaches facilitates the study of bottlenecks and assists in the analysis of traffic-flow characteristics, the movement of individual vehicles, and in the study of vehicle and driver characteristics.
