Pedestrian crossing behavior at signalized intersections consists of "entering the crosswalk" and "interactions at the crosswalk". According to the time when a pedestrian enters the crosswalk, pedestrian crossing behavior can be classified into four types: "Green Walkers (right behavior), "Late Walkers", "Risk Walkers" and "Early Walkers". Manoeuvres taken by either pedestrians or vehicle drivers to avoid collisions are called interactions, which can be distinguished by five levels depending on whether pedestrians/drivers obey traffic rules, intensity of interactions and executor of a manoeuvre. A case study at 5 representative crosswalks in Shanghai were carried out and behavior of 1328 pedestrians was analyzed in order to find out pedestrian behavioral characteristics and evaluate pedestrian safety at signalized intersections. The results showed that pedestrian non-compliance was rather serious in Shanghai, 44 percent of the pedestrians arriving during non-green time crossed on Red. According to the regression model, average pedestrian delay was found to be the most sensitive influencing factor, follows was average headway of conflicting vehicles and crossing distance. "Lane (group)-based tactic" and "side-based tactic" used by non-compliant pedestrians to cross the street resulted in high risks for Risk Walkers. Green Walkers took manoeuvres frequently to yield to turning vehicles, due to the Right Turn on Red, unreasonable control method of turn movement and low traffic discipline of drivers.
