Non-signalized intersection vehicle guiding device and non-signalized intersection vehicle guiding method

Abstract

The invention discloses a non-signalized intersection vehicle guiding device and a non-signalized intersection vehicle guiding method. The non-signalized intersection vehicle guiding device comprises a non-signalized intersection vehicle information collection module, a non-signalized intersection vehicle information processing module and a non-signalized intersection vehicle guiding module, wherein the non-signalized intersection vehicle information collection module is formed by a camera and a magnetic induction coil; the camera is used for acquiring the distance between vehicles within an intersection induction distance D and an intersection entrance driveway stop line and the driving speed of each vehicle; the non-signalized intersection vehicle information processing module is used for forecasting the time that the vehicles within the intersection induction distance D pass through an intersection and calculating the maximum alert speed and the minimum alert speed during driving of the vehicles; the non-signalized intersection vehicle guiding module comprises a mobile projection system which is arranged at the right side of a driveway and a dynamic display screen which is arranged beside the intersection entrance driveway stop line; the mobile projection system is used for guiding the vehicles to drive between the intersection induction distance D and a brake distance L; the dynamic display screen is used for guiding the vehicles to drive within the brake distance L. The traffic capacity of a non-signalized intersection is increased as much as possible under the situation that the safety of the vehicles is ensured.

Description

technical field [0001] The invention belongs to the field of intelligent traffic safety control, in particular to a vehicle guiding device and a guiding method at an unsignalized intersection. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the number of motor vehicles has increased significantly, and roads have continued to expand. In the process, there inevitably appeared a considerable number of level intersections without signal management and control. Due to the small traffic volume at these intersections, some drivers drive fast, and it is often difficult to avoid traffic accidents when vehicles approach from other directions at the intersection; at the same time, some drivers drive cautiously and drive slowly, resulting in unnecessary delays . [0003] A search of existing patents on this issue found: [0004] The patent "Vehicle-Vehicle Collaborative Collision Avoidance System at Unsignalize...
