Pedestrians' Safety Perception at Signalized Intersections in Shanghai

Pedestrians are the most vulnerable users at signalized intersections, and their incorrect behaviors such as signal violation, and not crossing at crosswalks etc., which is greatly determined by their safety perceptions, makes the situation even worse. To understand pedestrians’ perception can help traffic engineers to improve facility planning, design and operation so as to provide better experiences of pedestrians crossing at signalized intersections. The study conducted intercept survey at 32 crosswalks in Shanghai, 1286 pedestrians were asked to rate their safety perception from 1 to 5. Pedestrian behavior types have been categorized into three types according to the signal indications when they enter crosswalk, namely Green walkers (GW) who enters in green, Late walkers (LW) who enters in flashing green, and Red walkers (RW) who enters in red. A random-effects ordered logit model has been developed and estimated, the results showed that the refuge island settings and being involved in conflicts had significantly impacts on pedestrian perceptions. All types of pedestrians are in favour of the presence of refuge island, however, LW feel safer if they can stop at refuge island, while the RW perceive less safe. Some recommendation on crosswalk design and operation are proposed based on the conclusions.
