A multi-mode coordinated allocation method of urban road cross-section resources

Abstract

The invention discloses a multimode city road cross section resource coordinated configuration method. The method includes the steps that firstly, whether a bus-only lane is set and what cross section form is adopted are determined according to set red line width and design requirements; then, road supply conditions of motor vehicles are determined, whether mixing of cars and buses occurs and the width of each motor way are determined, traffic conditions are determined, the passenger transport efficiency and emission rate of each transport means per standard unit width are determined again, and then an objective function with the highest cross section passenger transport efficiency and the smallest emission rate and corresponding constraint conditions are established; finally, the objective function is solved to obtain key parameters in the optimization process and a cross section resource allocation result. Under the road conditions and traffic conditions of the set red line width, a cross section layout design scheme achieving the high road cross section passenger transport capacity and the small emission quantity can be provided.

Description

technical field [0001] The invention relates to a multi-mode method for coordinating the allocation of cross-section resources of urban roads, which belongs to the field of urban traffic planning. Background technique [0002] my country's cities are in a compact layout, the population in the built-up area is highly dense, and the land resources in large and medium-sized cities are in a state of extreme shortage. With the improvement of my country's urbanization level and urban social and economic development level, this situation will further intensify. In addition, the number of motor vehicles in cities is growing rapidly, and the resulting traffic congestion and environmental pollution problems are becoming increasingly serious. Therefore, it is particularly important to scientifically and rationally allocate cross-sectional resources of urban roads and to improve the utilization efficiency of land resources as much as possible under the premise of meeting the needs of mu...

AI Technical Summary

Problems solved by technology

For the planning and design of urban road cross-sections, various countries have corresponding norms, especially the United States and Japan, but these design norms still give the range of the width of each lane, and when designing the road cross-section, Too much attention has been paid to the passage of "roads", and the efficiency of passage has become an increasingly important measure, while ignoring or even giving up the original role of "street" in life

In addition, the overall design of the cross section did not take into account the environmental pollution caused by motor vehicles
