Abstract

The shared space concept develops a slow and safe environment with promoting a sense of vigilance and responsibility. This is achieved by reducing demarcation and any physical distinctions between the streets and pedestrian areas. However, there is a need to identify the conditions under which shared space is a feasible alternative to traditional controlled traffic designs. Predicting and visualising the responses of pedestrians to the behaviour of drivers, neighbouring pedestrians or obstacles in a shared environment is important from the standpoint of traffic management. Thus, a microscopic model based on the Social Force Model (SFM) is developed for shared space users. Since human beings aim is to follow the shortest path in order to reach their destination, this feature is added using the Distance Potential Field. This mathematical approach is meant to be the fundamental framework for a future simulation of shared space users. In order to calibrate this new modified SFM, parameters are initialised based on the observation made from New Road in Brighton. The paper presents a calibration approach and describes how to evaluate the results.
