摘要
本文在长春市1984年居民出行调查资料的基础上,用运输系统分析的理论和方法,建立了适合我国城市的客运模型系统——四步骤模型,并对重力模型进行了标定。综合费用函数可用作预测公交和自行车出行量比率。
For solving the passenger transportation problem, we made a survey in Changchun in 1984. Based on this trip survey, we developed four-step modles and calibrated the gravity model. The calculated value with these models has a good fitness to the surey data. This method for calibration of a model has a simple and precise calculation, that is better than the traditional ones with iterative calibration. The generalized cost function can be used for forecasting the ratio between transit and bicycle trips. Because We have adopted several simplified ways, it can save computer's memory and make the convergence faster in calculation. The material and information obtained from these medels are accepted by the authorites.
