Traffic passage prompting method and device based on green wave band

Abstract

The invention discloses a traffic passage prompting method and device based on a green wave band. The prompting method comprises the steps of obtaining green light information corresponding to a firstlane on a green wave band road in real time; turning on a light-emitting unit according to green light starting time in the green light information; obtaining the arrangement number of the light-emitting bricks; according to the arrangement number and the duration of the green light, obtaining the light-emitting prompt time of each light-emitting brick; and controlling the corresponding light-emitting brick to be in the first light-emitting state according to the light-emitting prompt time. According to the invention, the light-emitting unit corresponding to the first lane is controlled to bein the first light-emitting state through the green light information obtained in real time, road surface green light prompting is performed on a motor vehicle driver on the first lane, so the situation that a driver passes through the intersection along with red light running due to the fact that a front motor vehicle blocks sight is effectively prevented, and the safety of intersection passingis improved; the light-emitting bricks are not affected by factors that traditional coating marked lines are prone to peeling and peeling and visibility is not high in severe weather, and the servicelife is longer.

Description

technical field [0001] The invention belongs to the technical field of road traffic equipment, and in particular relates to a traffic prompting method and device based on green wave bands. Background technique [0002] With the in-depth reform and rapid development of economic construction, the urban population has increased significantly, and the total number of motor vehicles has also continued to increase, resulting in increasingly serious traffic jams and traffic chaos in large and medium-sized cities. In order to improve these phenomena, the main measure at present is to build new roads to disperse the over-concentrated traffic flow, but the cost of new roads is high and time-consuming, and it cannot fully meet the needs of road traffic. Therefore, how to effectively utilize the existing road network resources has become one of the current research hotspots in road traffic. [0003] The in-depth investigation of road traffic from the perspective of motor vehicle driver...

Problems solved by technology

[0004] (1) When the front motor vehicles (such as trucks, buses, etc.) block the line of sight due to the large size of the vehicle body, the driver of the rear motor vehicle cannot see the traffic lights in time, so it is easy to drive through the intersection with the rear motor vehicle. The situation of running a red light occurs, and the resulting traffic accidents account for more than 10% of the total traffic accidents, and the number of deaths and injuries is countless

In order to avoid the occurrence of this situation, motor vehicle drivers need to maintain a sufficient lookout range to see the signal lights at the intersection, but this will widen the distance between vehicles and cause the distance of motor vehicles to become longer. The number of motor vehicles at intersections decreases, which increases the traffic pressure on the road;

[0005] (2) Lane boundaries are usually formed by paint. After a period of use, the paint is easy to peel off. If it is not repainted in time, it is easy to mislead the driver's judgment of the markings, especially when the boundary near the intersection is from the actual When the line peels off into a dotted line

In addition, under severe weather conditions such as cloudy, rainy, and foggy conditions, the reflective ability of the paint is limited, and it is difficult for the driver to see the lane boundary in time, resulting in frequent occurrences of line pressing and driving into the wrong lane, resulting in traffic accidents countless
