Problems solved by technology

The above two measures can improve the driver's driving behavior to a certain extent, but each has its own limitations: the cost of smart instruments is very high, they can only be installed on high-end vehicles, and it is difficult to popularize them, and the accuracy of smart instruments is limited. Influenced by uncertain factors such as weather and surrounding environment, the scope of adaptation is narrow; the vibrating shoulder can only remind the driver when the vehicle deviates from the lane, and cannot prevent problems before they happen

Embodiment 1

[0034] A kind of method utilizing self-cleaning asymmetrical edge rate marking tunnel curve vehicle track, its steps are:

[0035] 1) Set edge rate marking lines at the heights of 1.2m and 1.8m on the walls on both sides of the tunnel respectively, and the height and width of the marking lines are 0.5 or 0.6 or 0.7m and 0.14 or 0.15 or 0.16m respectively;

[0036] 2) The edge rate marking line adopts energy-storage self-luminous material, and the energy-storage self-luminous material is laid on the aluminum alloy base plate, and its thickness is not less than 1.0mm;

[0037] 3) Lay photocatalyst material on the edge rate marking line, the photocatalyst material is Shupai SP01 type;

[0038] 4) Collect the driving trajectory of the vehicle in the tunnel curve, and analyze its relative position to the center line of the lane;

[0039] 5) If the vehicle trajectory in step 4) is biased towards the right wall, the density of the edge rate markings on the right side is greater than...

Embodiment 2

[0050] Simulate the tunnel curve road section implementation through a fully immersive driving simulator Utilize the driving trajectory and driver safety perception level under the condition of self-cleaning asymmetric edge rate marking, set the probability of driving trajectory deviation from the center line, safety perception level and driver driving comfort 3 indicators such as degree to compare and evaluate the implementation effect with or without the said marking line.

[0051] test group

[0052] Its implementation steps are identical with embodiment 1.

Abstract

The invention discloses a tunnel curve vehicle driving route marking method with self-cleaning edge ratio marks. The method comprises the steps that 1), according to the visual heights of drivers of vehicles of different sizes, the edge ratio marks are arranged at the corresponding heights on both side walls of a tunnel; 2) the edge ratio marks are made of silicate system light accumulating luminescent materials; 3) photocatalyst materials are laid on the edge ratio marks; 4) the driving routes of the vehicles at the curve of the tunnel are collected, and the positions of the driving routes relative to the central line of lanes are analyzed; 5) when the driving routes of the vehicles are closer to the right wall, the density of the right edge ratio marks presents to be higher than that ofthe left edge ratio marks; 6) when the driving routes of the vehicle are closer to the left wall, the density of the left edge ratio marks presents to be higher than that of the right edge ratio markers; 7) the driving speeds of the vehicles at the curve of the tunnel are collected; 8) the longitudinal spacings on the sides with high and low edge ratio mark density are determined according to a formula. The tunnel curve vehicle driving route marking method with the self-cleaning edge ratio marks is easy to implement and simple in arrangement and can guide the drivers to actively optimize the driving routes at the curve of the tunnel and further to improve the traffic safety.

Description

technical field [0001] The invention belongs to the field of traffic safety, and more specifically relates to a method for driving vehicle tracks on curves of expressway tunnels by using self-cleaning asymmetrical edge rate markings, which is suitable for improving the traffic safety level of bends in expressway tunnels. Background technique [0002] In China, there were 23,038 traffic accidents on curves in 2016, and the death rate of traffic accidents on curves was about 1.3 times that of straight roads. The driver's failure to properly adjust the lateral position of the vehicle is the main cause of frequent accidents on curves. [0003] At present, there are two main auxiliary measures for the driver's lane keeping: 1. Install intelligent instruments on the vehicle to assist the driver's lane keeping; 2. Set a vibrating shoulder on the edge of the road, and the vehicle will vibrate when the driver deviates from the lane And make a "rumbling sound" to remind the driver to...
