Embodiment Construction

[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0059] Such as figure 2 As shown, the steps of the roadside guidance method based on vehicle-road coordination in this embodiment include:

[0060] S1. The designated area on the entrance road at the destination intersection is used as the guidance area in advance, and the guidance and indication units are arranged along one or both sides of the road in the guidance area;

[0061] S2. When the vehicle arrives at the guidance area on the entrance road of the destination intersection, obtain the vehicle state information of the current vehicle, the road condition information of the entrance road of the current destination intersection and the information of the signal lights at the destination intersection;

[0062] S3. According to the acquired vehicle state in...

Abstract

The invention discloses a roadside type guide method and system based on vehicle-road cooperation, and the method comprises the steps: S1, taking a specified region on an entrance lane of a target intersection as a guide region in advance, and arranging guide indication units along one side or two sides of a road in the guide region; S2, when the vehicle arrives at the guiding area, vehicle stateinformation of the current vehicle, acquiring road condition information of an entrance lane of a current target intersection and state information of a signal lamp at the target intersection; and S3,according to the obtained information, controlling a guide indication unit to send indication information, so as to guide the current vehicle to stop or decelerate in advance if there is a queuing vehicle when the current vehicle reaches the target intersection or the current vehicle cannot pass through the intersection stop line in the yellow light time. The method has the advantages of being simple in implementation method, low in implementation cost and complexity, safe and reliable in vehicle driving, high in intersection communication efficiency and the like.

Description

technical field [0001] The present invention relates, in particular, to a roadside guidance method and system based on vehicle-road coordination. Background technique [0002] There will be a dilemma at the entrance of the intersection. The dilemma refers to the area where the vehicle can neither pass the intersection stop line at the maximum speed limit nor park the vehicle safely inside the intersection stop line during the yellow light period. ,Such as figure 1 shown. When the vehicle enters the dilemma zone, no matter how the driver makes a decision, it is inevitable that the phenomenon of running a red light and slamming the brakes will inevitably occur, which has great potential safety hazards and has therefore attracted widespread attention. [0003] To alleviate the problem of vehicles entering the dilemma at intersections, the following methods are mainly used at present: [0004] 1. How to set the flashing time of the green light. This type of method is to remi...
