Quantitative Analysis Of Traffic Efficiency And Its Influencing Factors

City traffic efficiency and its influencing factors analysis, is not only the city road network planning and design the important basis, also determine the city road construction scale, form as well as the road construction project feasibility study is an important premise for city road construction, evaluation and other aspects of the provision of scientific theory.This paper analyzes on the traffic capacity of the road and the traffic efficiency research, analysis of road traffic flow and traffic capacity of the basic concept, introduced on the basis of the concept of passage efficiency. Passage efficiency of a road section, a specific time unit width of pavement can be adopted by the maximum number of individuals per meter, width of the road through the number of unit time, unit (P/h· m), this concept can be motorized vehicle lane, the lane for non-motorized vehicles and the sidewalk three modes of transport capacity unified quantitative analysis, it can be compared to the results of the analysis.Secondly analyses and summarizes the effect of passage efficiency four kinds of influencing factors, including roads, traffic, traffic control and environmental conditions, and analyzed by detailed description. Based on this the city road traffic efficiency theoretical model, and were on the road on a motor vehicle, non-motorized vehicle and pedestrian access efficiency are quantitatively analyzed, and three kinds of transport traffic efficiency were compared and summarized. In particular the road condition, city road section pedestrian traffic with highest efficiency, non-motor-vehicles traffic efficiency with minimum.Then it analyzes the city road section bus stops on road traffic efficiency, a detailed analysis of the bus on the capacity influencing the main aspects, namely public transit time, and of linear type and the bus stations all kinds of cases classified summary.Again through field survey data, analysis of different stop form bus arrival frequency and public transit time relationship between the model; on this basis, combined with the prior to the city road motor vehicle, non-motorized vehicle and pedestrian traffic efficiency analysis model and the quantitative index, gives the straight line type and two different types of harbor type bus stops at different bus arrival frequency under the condition of the city road motor vehicles, non-motor vehicles and pedestrians efficiency influence the quantitative analysis results:for the bus station, bus arrival rate on vehicle impact is less than the non-motor vehicle, beeline bus stop is opposite with the.The final analysis of city road plane curve on road passage efficiency influence, through to the curved section vehicle maximum safe speed and the Sideway Force Coefficient Analysis, combined with the city road motor vehicle, non-motorized vehicle and pedestrian traffic efficiency theoretical model and quantitative index, gives the city road section simple curve curvature radius on road motor vehicle non motor vehicles and pedestrians, quantitative analysis of the influence of efficiency. In particular the road condition, bend curvature for motor vehicle traffic impact is less than the non-motor-vehicle, and for pedestrian traffic, bend curvature almost does not affect traffic efficiency.
