Embodiment 1

[0034] combine Figure 1-2 , take two-way 12 lanes as example, originally there are 2 left-turn special lanes, 3 straight lanes, and 1 right-turn special lane, the present invention changes an original left-turn special lane into a variable lane.

[0035] The method adopts a video detector, a direction indicator light, a lane signal light and a lane change controller, and the steps are as follows:

[0036] Step 1: Setting Up the Video Detector

[0037] The video detector is installed on the cross arm of the signal light facing the entrance or on the electronic police pole in the direction to detect the flow data of each flow direction of the stop line at the intersection during the green light of each phase of the entrance in real time.

[0038] Step 2: Set up the lane signal lights

[0039] A cross-arm or gantry-type lane signal light is installed at a suitable position behind the stop line to indicate the function of the entrance lane in each signal cycle (turn left, go st...

Abstract

The invention discloses a method for improving space resource utilization efficiency of an intersection entrance lane. The method for improving the space resource utilization efficiency of the intersection entrance lane includes that setting the left turn lane of the outermost side of the entrance lane into a reversible lane without changing the period and phase green light time, and changing functions of the reversible lane in real time so as to improve the space resource utilization efficiency of the same entrance lane of the intersection; gathering the left turn car traffic volume and straight going car traffic volume of the entrance lane in the signal period through a video detector, and changing a lane signal lamp and a direction indication signal lamp in the next period through numeric calculation and logical judgment so as to guide a vehicle to adapt to the lane conversion. The method for improving the space resource utilization efficiency of the intersection entrance lane balances the space resource utilization efficiency of different directions of lanes of the intersection, timely reduces the queuing time of the vehicle at the intersection and improves the traffic efficiency.

Description

technical field [0001] The invention relates to traffic science, in particular to a method for improving the space resource utilization efficiency of an intersection approach road. Background technique [0002] With the continuous growth of urban road traffic demand and the improvement of the road network, there are more and more urban arterial roads such as two-way 10 and 12 lanes, and there are even widening lanes at intersection entrances, making the number of left-turn special lanes gradually increasing. Increase. At a typical four-phase intersection, when there are multiple left-turn lanes, its traffic capacity can basically meet the traffic demand during peak hours; The traffic flow is heavy, and the space resources of the through lane are very tight, and the two form a huge contrast. Contents of the invention [0003] Based on the above deficiencies, the object of the present invention is to provide a method for improving the space resource utilization efficiency ...
