A Dynamic Line Restriction Method Based on Path Analysis

Abstract

The invention discloses a dynamic traffic restriction method based on route analysis. The method comprises steps of: firstly acquiring road information and constructing an urban traffic network; then, extracting traffic flow information based on cell phone data; allocating all traffic flow to the urban traffic network by using a traffic flow allocation algorithm to obtain the allocated traffic of each road segment in the urban traffic network; obtaining the traffic source information of a bottleneck road segment based on the allocated traffic of the road segments, and extracting a main route from the traffic source to the bottleneck road segment, obtaining intersections with traffic lights on the main route as signal control ports; and finally, using a genetic algorithm to selectively control each signal control port in order to achieve dynamic traffic restriction. The method, by analyzing the main dynamic traffic source that cause road congestion, extracting the main route of the traffic source and the signal control ports on the main route, and controlling the extracted signal control ports, achieves a purpose of alleviating congestion and controls the congestion from the source.

Description

technical field [0001] The invention belongs to the technical field of transportation, and in particular relates to a dynamic traffic restriction method based on path analysis. Background technique [0002] With social progress and economic development, urbanization continues to accelerate, and car ownership and utilization rates continue to increase, leading to increasingly serious urban congestion. Traffic congestion will bring many problems such as environmental pollution, resource consumption, increased travel time, and affect the travel efficiency of travelers. In order to solve the problem of urban traffic congestion, various methods such as traffic demand control, road network optimization, route guidance strategy, and vehicle restriction control have emerged to alleviate traffic congestion from different aspects. Among them, from the perspective of vehicle control, the vehicle traffic restriction strategy generally refers to controlling the overall traffic demand by...

Problems solved by technology

[0003] 1) The method of restricting traffic from the perspective of vehicle control can quickly reduce traffic demand in a short period of time as a coercive means, but it is not conducive to the acceptance of travelers and brings difficulties to travelers

[0004] 2) The current method of vehicle restriction strategy from the perspective of signal control is often to alleviate congestion, and cannot control the congestion problem from the source; Dynamic regulation
