Problems solved by technology

To solve this problem, Lu Kai used the model method (MAXBAND model) to generate a set of coordinated control schemes, evaluated the control schemes by using the driving speed samples, and selected the scheme with the largest expected bandwidth or the highest degree of connection as the best scheme. This method takes into account the speed properties of interval fluctuations, but does not address improvements in the nature of coordinated control models

Embodiment Construction

[0055] The present invention will be further described below in conjunction with specific examples.

[0056] as attached figure 1 As shown, the green-wave coordinated design method for imported single-release arterial roads suitable for driving speed fluctuations described in this embodiment includes the following steps:

[0057] S1. Determine the phase sequence of the signals at each intersection of the arterial road;

[0058] The signal phases of each intersection in S1 are an uplink coordinated phase, a downlink coordinated phase, and a non-coordinated phase. The coordinated phase of each intersection adopts separate clearance at the entrance, and the non-coordinated phase can adopt separate clearance at the entrance, symmetrical clearance at the entrance, or overlapping clearance at the entrance.

[0059] There are two ways to set the signal phase sequence of the intersection in S1. One is uplink coordinated phase→downlink coordinated phase→non-coordinated phase; the se...

Abstract

The invention discloses an inlet individually passing type truck road green-wave coordination design method suitable for driving speed fluctuation. The method includes the steps of determining signal phase sequence of each intersection in a truck road, determining the green time ratio of different phases of each intersection in the truck road, determining the value of a common signal period of the truck road, calculating speed fluctuation percentage of adjacent intersections of the truck road, establishing a green-wave coordination control model that meets the driving speed fluctuation, solving the green-wave coordination control model, and obtaining the green-wave coordination control parameters. A coordination control scheme, which meets the requirement of no traffic jam when vehicles in the head of a fleet drive at a high speed and the last vehicles of the fleet drive at a low speed, can be generated, so that more vehicles can pass through an intersection without braking.

Description

technical field [0001] The invention relates to the field of coordinated control of arterial traffic signals, in particular to a green-wave coordinated design method for imported single-release arterial roads suitable for fluctuations in driving speed. Background technique [0002] With the increasing traffic volume of urban roads and the increasing density of road network, the connection between various intersections in the road network is also increasing. Therefore, considering the signal control problem of an intersection alone often cannot effectively solve the traffic congestion problem of the entire arterial road. Therefore, in order to reduce the parking time of vehicles at each intersection on the arterial road and pass through the entire arterial road without stopping as much as possible, it is necessary to connect the traffic signals of each intersection on the arterial road in a certain way and coordinate and control them, thus forming an arterial road Green wave...
