Abstract:

Microscopic simulation models have been widely used in traffic system management,control and optimization.Parameter calibration is necessary before the application of traffic simulation software. Calibration of microscopic traffic simulation models under pedestrian and vehicle interweaving case is even more challenging.Taking the microscopic simulation software VISSIM as an example,the calibration problem is studied when pedestrian and vehicle are interwoven in microscopic traffic simulation models,and a procedure for parameters calibration is proposed by applying genetic algorithm. Using actual data,parameters of vehicles and pedestrians at airport curbside of the T3 terminal at Beijing Capital International Airport are calibrated.The efficiency and accuracy of the simulation test is effectively improved,which verifies that the proposed method is useful.

Key words: pedestrian, traffic simulation model, VISSIM, parameter calibration
