A vision-guided urban tunnel vehicle acceleration control system and method

Abstract

The invention proposes a vision-guided urban tunnel vehicle acceleration control system and method. In the present invention, the ink screens are arranged on both sides of the inner wall of the middle section of the tunnel according to the spacing from sparse to dense and the length from long to short on the middle section of the tunnel, and speedometers are installed at the entrance, exit and middle section of the tunnel to detect the speed of traffic in real time , and transmit the data to the ink screen control terminal in the middle of the tunnel. When the speed of the traffic flow in the middle of the tunnel is significantly lower than the speed of the traffic flow at the tunnel entrance or tunnel exit, the ink screen display is controlled. The arrangement of lines on the ink screen affects the distance of the driver in the driver's field of vision. Perception, showing a higher sense of distance in the driver's perception, thereby increasing the driver's perceived distance, and then inducing the driver to actively accelerate. The invention can improve the traffic bottleneck problem of urban tunnels, change the visual reference object relationship of the driver's spatial distance perception, increase the driving speed of the driver in the urban tunnel, and significantly improve the traffic efficiency of the tunnel.

Description

technical field [0001] The invention belongs to the technical field of road engineering and traffic control, and in particular relates to a vision-guided urban tunnel vehicle acceleration control system and method. Background technique [0002] As an important link in the urban road network, urban tunnels tend to become traffic bottlenecks in the urban road network due to their limited regional road network and difficult traffic organization, leading to tunnel traffic congestion and even regional traffic paralysis. Drivers often take deceleration measures to adapt to the environment when they are in the form of tunnels. When the traffic flow in urban tunnels is close to saturation, the deceleration behavior of some vehicles in the tunnel section will cause traffic flow bottlenecks, thereby reducing the efficiency of tunnel traffic. [0003] At present, most of the measures used to improve the "bottleneck" of tunnel traffic are to improve road conditions and traffic evacuatio...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the measures used to improve the tunnel traffic "bottleneck" are to improve road conditions and traffic evacuation methods, and the implementation cost is relatively high. In order to improve the effect of improving the tunnel bottleneck, a new measure needs to be proposed. From the perspective of the driver, Actively induce the driver to increase the vehicle speed appropriately, improve the bottleneck problem of urban tunnels, and improve traffic efficiency
