Pedestrian Level of Service at Signalized Intersections in China Using Contingent Field Survey and Pedestrian Crossing Video Simulation

As China motorizes, the number of motorized vehicles and non-or semi-motorized vehicle conflicts is increasing. Pedestrians are the most vulnerable users of signalized intersections in urban areas and context sensitive methods are required to improve their experience. This study proposes a reliable and convenient investigation method to estimate pedestrian level of service (LOS) based on Chinese traffic environments and Chinese pedestrians’ perceptions. A modified method of pedestrian simulation was developed, Pedestrian Crossing Video Simulation (PCVS) and the reliability and validity of the method was corroborated with Contingent Field Survey (CFS) analysis. The LOS estimation methods were conducted on 12 selected crosswalks. Experimental results showed that PCVS has the characteristics of immersion and reality based on consistent perceptions of pedestrian LOS between the two methods Factors influencing pedestrian LOS were investigated using two approaches, Pearson correlation analysis and stepwise regression analysis. The regression analysis (R² =0.65) revealed intuitive signs and magnitudes of significant variables that influence LOS; increases in delay, turning traffic, mixed two-wheeler volume, and pedestrian delay have negative impacts to LOS. Pedestrian volume and the presence of a refuge island enabling a two-step crossing both improve pedestrian LOS.
