technical field

The invention relates to the technical field of road safety, in particular to a road tunnel middle guiding device which can improve driving attention.

Background technique

As of the end of 2016, there were 15,181 tunnels in my country, with a total length of 14.0391 million meters. It is the country with the most and most complex tunnels in the world. The huge energy consumption of highway tunnel lighting and the outstanding tunnel traffic safety problems have always been the focus of tunnel research. At present, my country's tunnels lack corresponding induction devices. Although some tunnels are equipped with reflective rings inside, the internal lighting environment of the tunnel can be improved by reflecting vehicle lights. Practice has proved that the reflective ring can replace some lighting fixtures, reduce energy consumption of tunnel lighting, and ensure safe driving of drivers. It has a broad application prospect.

According to the driving task hierarchy model, when driving inside the tunnel, the driver has the following driving task requirements from low to high: control the vehicle to maintain the speed, maintain the distance from the vehicle in front, obey the traffic markings, signs, signal lights and operate safely, according to (Guide) sign information and road landmarks for route selection. The primary task of safe driving is to keep the driver's sight in front of the vehicle during driving, so as to make corresponding driving adjustments according to the tunnel traffic conditions. The existing reflective ring has the same reflective brightness as a whole under the illumination of vehicle lights. According to relevant drivers, during the driving process, due to the consistency of the overall brightness of the reflective ring, the line of sight will be unconsciously concentrated on the top of the tunnel, resulting in distraction and affecting driving safety.

Therefore, the prior art still needs to be improved and developed.
