Embodiment 1

[0042] Embodiment 1 A traffic guidance system for self-adaptive vehicles at intersections and far-leading U-turns

[0043] refer to figure 1 , figure 2 , the intelligent U-turn vehicle guidance system of the present invention includes: traffic information collection equipment, main control equipment 3, traffic signal control machine 4, information guidance equipment, variable road separation facilities; wherein, the traffic information The collection equipment includes: a loop coil vehicle detector 1 for real-time collection of traffic information and a camera video collection system 2;

[0044] The loop coil vehicle detector 1 is buried under the four entrance road surfaces of the intersection. The loop coil vehicle detector is a detector that uses an induction coil to detect the speed of the vehicle, and is a very important part of the road monitoring system. It can obtain data such as current monitoring road traffic flow, occupancy rate, speed, etc., so as to judge road...

Embodiment 2

[0054] Embodiment 2 A control method of an intersection self-adaptive vehicle far lead U-turn traffic guidance system

[0055] see Figure 4 , the control method of the above-mentioned vehicle far-turning intelligent traffic guidance system, assuming that the initial state variable road separation facility is in a closed state, that is, the LED light 7 is displayed as a red light, including the following steps:

[0056] Step S1, collect the traffic flow data at the intersection by the loop coil vehicle detector 1, and collect the motor vehicle video image data by the camera video collection system 2;

[0057] Step S2, transmitting the real-time traffic flow data collected by the loop coil vehicle detector 1 and the camera video acquisition system 2 to the data storage module 31 in the main control device 3 through wifi;

[0058] Step S3, the traffic state inspection module 32 in the main control device 3 reads the data in the data storage module 31; i , compare this data wit...

Abstract

The invention discloses an intersection self-adapting vehicle far-leading U-turn traffic leading system and a control method. The intersection self-adapting vehicle far-leading U-turn traffic leading system comprises traffic information acquisition equipment, main control equipment, traffic signal controller, information guiding equipment, and a variable type road separation facility. The traffic information acquisition equipment comprises annular coil vehicle detectors and a camera video acquisition system, which are used for real-time acquisition of traffic information. The annular coil vehicle detectors are embedded under four inlet pavements of the intersection, and are used to transmit the data to the main control equipment by a WiFi interface. The camera video acquisition system is disposed on a monitoring column, and is disposed on a weaving area, and is used to transmit the data information to the main control equipment by the wifi. According to the design basis of the intersection self-adapting vehicle far-leading U-turn traffic leading system, the real-time traffic flow data is used as a guiding strategy, and opening positions of separation bands are adjusted in a real-time manner according to vehicle driving time, motor vehicle delay, and other indexes, and therefore maximization of road network passing efficiency is guaranteed.

Description

technical field [0001] The invention relates to an intersection self-adaptive vehicle far-leading U-turn traffic guidance system, which belongs to the field of intelligent transportation and also relates to the field of photoelectricity. Background technique [0002] Far diversion at level crossings is an effective method to solve the problem of traffic flow turning after the flow direction of the intersection is restricted. When the road network has diversion and detour conditions, the U-turn traffic organization at the level crossing can be used to solve the problem of traffic pressure transfer on the road network caused by the ban on the left at the intersection, which is conducive to the load sharing of the intersection section. In recent years in China, some cities have implemented far-distance U-turns at some suitable intersections, and they have indeed achieved certain results. However, there are still many controversies about the driver's management strategy for som...
