Abstract

In this study the use of traffic simulation as a tool for evaluating various strategies and designing various signal models and also implementing pedestrian model in response of emergency situations is considered and briefed. This paper presents a traffic simulation approach for evaluating the pedestrian behaviour by developing a model which includes pedestrians in a vehicular micro-simulation model i.e. PARAMICS. This study is based on testing of the prototypes and actual signs in order to determine if they convey the desired message in the desired time. This will let the users know the usability of their signs and make them reach the desired safe destination easily. In this report, pedestrian characteristics during emergency are also studied using suitable pedestrian model (eg: Fruins pedestrian model). Application of this carfollowing algorithm demonstrated by calibrating in PARAMICS will be very useful in predicting known pedestrian speed-flow relationship. The model is developed especially to enhance the complex interaction between pedestrians and vehicles. This study indicates the importance of additional factors (i.e., Pedestrian queue discharge rate, Pedestrian gap acceptance, Pedestrian speed) which is to be related with the vehicle flow. It also shows the effort to better understand pedestrian level of service under various conditions. The high variability in data sets confines the simulation resulting in a constant queue discharge rate at flows approaching saturated conditions. This work finally concludes that PARAMIC’S car-following algorithm is very much helpful in reproducing vehicle and pedestrian flow in complex as well as heterogeneous urban traffic.
