Pedestrian Stream Flow Modeling using Single and Multi Regime Concepts

Analysis of stream flow parameters describes the relationships among the characteristics of pedestrian traffic stream. The level of functional effectiveness of pedestrian infrastructure can be measured and analyzed considering the relationships between stream flow parameters of pedestrian traffic. In this study single regime and multi regime models have been proposed for mixed pedestrian traffic condition on sidewalks and carriageways to develop a suitable traffic stream model for heterogeneous traffic condition. Very limitedstudied have been reported in this respect so far from India. Various types of pedestrian facilitiesand regimes based on density rangehave an impact on pedestrian walking behavior which differentiates the response of pedestrian micro-characteristics to its macro-characteristics. Two regime and three regime models have been explainedin the present study to characterize pedestrian traffic in different regimes such as free flow, transitional flow and congested flow regime. A suitable modelhas beendeveloped minimizing error values such as MAPE, RMSE valueand better fitness of predicted data to real situation. This study will be helpful for analyzing and improving pedestrian facilities in terms of efficiency and shall be used for developing the Highway Capacity Manual for India.
