| Abstract: | 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. |
