Problems solved by technology

[0003] The experience summary method is more practical and can be directly applied to examples; the traffic micro-simulation is close to random experiments, but it cannot be used as a means to evaluate the actual effect because it cannot reflect the actual situation; the traffic distribution theory is more focused on theoretical analysis and is difficult to apply In actual cases, and the assumptions of the method cannot reflect the real state of the road network
In contrast, the research on the evaluation of the policy effect of exclusive lanes based on empirical data is still insufficient

Embodiment Construction

[0109] The specific implementation manner of the present invention is described below in conjunction with the technical scheme, and the implementation effect of the invention is simulated.

[0110] 1. Selection of target road sections and preparation of regression data

[0111] Shennan East Road, located in Luohu District, Shenzhen City, is selected as the target road section. The bus-only lane is set on the outermost side of the road, and the opening hours are 7:30-9:30 and 17:30-19:30 when the traffic volume is relatively large every day. There are a total of 16 bus lines passing through the section, and there are two roadside stops. figure 2 Electronic map for the target road section.

[0112] Extract the data points of taxis and buses on Shennan East Road from 6:00 to 11:00 in the five days from June 9 to 13, 2014 as the regression basic data, and perform the average speed in SPSS software calculation. According to the floating car calculation model, the unit time peri...

Abstract

The invention provides a bus lane policy evaluation method based on breakpoint regression, which belongs to the technical field of bus lane policy evaluation technology. Using measured data to conduct breakpoint regression on the speed of two different types of motor vehicles, combined with image analysis of the mutation of the result variables before and after the breakpoint, quantitatively evaluate the impact of dedicated lanes on the speed of buses and social vehicles, and assist the urban transportation management department in formulating and To optimize the bus lane policy, this method is very cost-effective, and the conclusions drawn are direct and effective, and have certain promotion value.

Description

technical field [0001] The invention belongs to the technical field of urban traffic planning, relates to the field of public bus lane policy evaluation, and particularly relates to technical methods such as breakpoint regression. Background technique [0002] For the evaluation of the effect of bus-only lanes, the existing research methods mainly include practical experience summary, traffic micro-simulation, and traffic allocation theoretical analysis. Cox studied the application of bus lanes in Dallas in the article "RESERVED BUS LANES IN DALLAS, TEXAS"; ThamizhArasan and P.Vedagi constructed a new type of bus lane in the article "Microsimulation Study of the Effect of Exclusive Bus Lanes on Heterogeneous Traffic Flow" The micro-simulation model HETEROSIM under the state of mixed traffic flow simulates the behavior characteristics of motor vehicles in real situations, so as to evaluate the effect of bus-only lanes; Shuguang Li and Yongfeng Ju proposed a multi-mode dynamic...
