A method of traffic diversion during road construction

Abstract

The invention discloses a traffic diversion method during road construction. The method includes the following steps: step 1, determining a traffic affected area during road construction; step 2, acquiring traffic information in real time; and step 3, according to the traffic information of each road section, Calculate the service level load degree of each road section, and combine its threshold to determine the congested road section; Step 4, for the congested road section, calculate the road network service level of the corresponding traffic affected area, and determine the traffic diversion scheme and traffic diversion scheme according to the road network service level Including the external diversion and internal diversion of the traffic affected area; Step 5, build a simulation platform to simulate the traffic diversion scheme; Step 6, select the optimal traffic diversion scheme according to the simulation results and corresponding evaluation indicators. The invention can effectively improve the traffic management efficiency during the road construction period, carry out real-time and precise management, and provide a decision basis for solving road congestion during the construction period for reference and use by urban traffic managers.

Description

technical field [0001] The invention relates to the field of traffic, in particular to a traffic diversion method during road construction. Background technique [0002] In the process of urbanization, the scale of the city has developed to a certain extent, and there are fewer and fewer new urban roads planned, and more and more renovation projects of old urban roads. While road reconstruction has brought traffic pressure to the city, it has also buried hidden traffic safety hazards in road construction areas. [0003] In the process of road construction and reconstruction, most cities conduct traffic management based on experience, which is limited to traffic management of construction roads, and does not take into account the traffic impact of construction roads on other surrounding roads. At the same time, once traffic congestion occurs on the construction road, the process from traffic congestion to on-site traffic investigation, giving a solution, and finally solving ...

While road reconstruction has brought traffic pressure to the city, it has also buried hidden dangers to traffic safety in road construction areas

[0003] In the process of road construction and reconstruction, most cities conduct traffic management based on experience, and it is limited to the traffic management of the construction road, without considering the traffic impact of the construction road on other surrounding roads

At the same time, once traffic congestion occurs on the construction road, the process from traffic congestion to on-site traffic investigation, giving a solution, and finally solving the problem takes a lot of time and cannot alleviate the traffic congestion in time

At present, the traffic research on urban road construction period is mostly from the qualitative point of view, and it is implemented based on experience in the actual management process, and the management of traffic congestion during the construction period cannot be quantified.
