Road intersection multiple virtual signal linear linkage control system and control method thereof

Abstract

The invention relates to the traffic flow control field and discloses a road intersection multiple virtual signal linear linkage control system and a control method of the road intersection multiple virtual signal linear linkage control system. The control system comprises a traffic flow detection device arranged at an intersection, linear linkage signal lamps and a linear linkage controller. The traffic flow detection device is used for detecting data of vehicles at the intersection. The linear linkage signal lamps are arranged on entrance lanes of the intersection respectively in the vehicle moving direction in sequence and at intervals. The linear linkage controller controls the linear linkage signal lamps to act in sequence according to detection data of the traffic flow detection device. According to the road intersection multiple virtual signal linear linkage control system and the control method of the road intersection multiple virtual signal linear linkage control system, a multiple-virtual-signal control mode is adopted, according to the real-time traffic condition, linear linkage control is carried out on each entrance lane, loss time in starting a vehicle can be eliminated, driver signal information collecting time and reaction time are reduced, thus the passing capacity of the urban road intersection is boosted and road congestion phenomena are reduced.

Description

technical field [0001] The invention relates to the field of traffic flow control, in particular to a traffic flow control system at a road intersection and a control method thereof. Background technique [0002] Road intersections are the stagnation points of urban traffic. To study and solve the traffic problems at intersections is the key to improving the transportation efficiency of the whole city. Delay at a signalized intersection is an important indicator to evaluate the traffic service level and operational efficiency of a signalized intersection. Intersection delay refers to the time delay for vehicles passing through the intersection. The classification of signalized intersection delays includes queuing delays, parking delays, control delays, lead Road delays, etc. [0003] Usually the vehicles entering the intersection often change their driving status due to the effect of traffic lights. Control delay is the delay caused by the traffic control device. When form...
