Study On Adaptation Of Pedestrian Crossing Facility On Road Sections

Pedestrian crossing facilities are the places where the conflict exists between the vehicle and pedestrian. The irrationality within the pedestrian traffic and vehicle traffic will result in excessive delays, low operating efficiency, and it will increase the possibility of the illegal crossing of pedestrian.By means of simulating pedestrian crossing the road,the paper targets on exploring the adaptation of pedestrian crossing facilities.First of all, make an introduction about the pedestrian crossing facilities, classify them with the principle of the space. Manifest the characteristics, merit and demerit from the aspect of dangerousness and adaption.Then, analyze the characteristics in service of pedestrian crossing facilities from the aspects of the allocation of road right and crossing capacity. And by field observation and interview, find the problem.Secondly, analyze the characteristics of crossing traffic.The vehicle characteristics is analyzed from the angle of traffic flow parameter and statistical distribution while the crossing traffic of pedestrian is analyzed by requirement of crossing, crossing behavior and crossing characteristics. And analyze the conflict from pedestrian crossing safe psychological distance, vehicle from the man-machine and human-computer analysis. At the same time,by doing the investigation and analyzing the consequence, improve the analysis of characteristics of crossing traffic.Then, on the basis of analyzing the characteristics of the street traffic, the establishment of motor vehicles and cellular automata pedestrian crossing cellular automata, and human-machine conflict rule will eliminate a combination of both to build pedestrian crossing cellular automaton model. In matlab programming for the carrier, and instance data into the simulation program, the feasibility and rationality of the model validation by comparison with the measured data.Finally, analyze the time of tolerance, on the basis of which and set the proper evaluation index. Establish the simulation conditions by combining every factor which affects the crossing traffic and set appropriate range and level. According to the sequence of plane to three dimension and non control to control, analyze the adaption of pedestrian crossing the road. Combining with the model, come up with flow path of pedestrian crossing facilities.
