Urban Road Proportion in Grades Based on Vehicle Trip Distance-Turnover Coupling Mechanism
Publication: International Conference on Transportation Engineering 2007
Abstract
One of the direct reasons that cause urban traffic problems is obscure functions and unreasonable road proportion in grades. Therefore, based on the statistic analysis of trip investigation data in several typical cities, the function with double parameters is adopted to fit the relationship between Vehicle Trip Distance (VTD) and trip proportion. Furthermore, the regressing analysis of the fitting parameters is made by three infection factors. In addition, equilibrium equations are built to show the equilibrium relationships between vehicle supply-demand turnovers in each grade of roads. As a result, urban road proportion in grades is deduced and fields of urban road proportions in grades are recommended in different scale cities.
