Abstract: As for the mixed urban traffic, the influence between the pedestrians walking cross road sections and the normal driving of motor vehicles is so significant that it results in traffic jams. Firstly, this research summarizes the problems of pedestrians crossing facilities at crosswalks, overpasses, underground passages and sidewalks and pedestrians crossing signals. Thereafter, this study proposes the measures to solve these problems, including reasonably setting crosswalks and pedestrian crossing signals, sidewalks, overpasses and underground passages, non-motor-vehicle lanes and traffic signs and markings. Finally, the research on the optimization of the twice crossing signals for the pedestrians in the east area of the bus stop of Changchun Street Intersection East. It is shown that, the systematic signals for adjacent intersections makes the effective time for pedestrians crossing roads increase 25% in evening peak hours, and the efficient time of the green signals increases 20% in the non-peak hours at noon.
