A Cost Effective Methodology for Pedestrian Road Crossing for Developing Countries

The objective of this paper is to present a low-cost methodology for the selection of proper pedestrian crossing facility by anticipating pedestrian delays at interrupted and uninterrupted flow and to correlate the pedestrian delays with level of service based on 6 levels which are ranked using the human's perceptions of comfort, safety and psychological limitation as well as acceptable delay. This paper focuses on the application of statistical distributions to model traffic and pedestrian flows. A Monte Carlo technique used to simulate traffic and pedestrians, and discusses how to create a tool in order to quantitatively rank which pedestrian facility is appropriate for particular situation. Initially pedestrian delay can anticipate at an unsignalized intersection. If the pedestrian delay is found to be more in uninterrupted flow, then signalized facility will be simulated. Later, the effect on vehicle delay at signalized intersection will be simulated. Finally delay simulation outputs will be used for the selection of pedestrian facility either unsignalized crosswalk, signalized cross walk or grade separated pedestrian facility. Thus, the simulation results gained in this study should be useful for enhancing the current assessment of facility. It is also hoped that the developed model could be used as a reference source for other Asian cities with similar pedestrian and traffic flow characteristics.
