Background technique

For the horizontal and vertical combined sections of expressway tunnels, the driver will complete the driving task on the curved section in a short period of time. On the curved section, the driver's line of sight is poor, and the special environment in the tunnel may easily lead to the driver's sense of the curve and the slope. There is a deviation in the judgment, and the special road section of the combination of curved slopes will cause the driver to have greater physical and psychological discomfort when driving on this road section. The driving task of the horizontal and vertical combined road sections of the tunnel is complex, which is easy to cause changes in the driver’s driving psychology. The vehicle speed and driving trajectory often have large fluctuations, which are manifested as: it is easy to overspeed on the curved road section, the driving trajectory is offset, and the lane is maintained.

Therefore, accidents such as rear-end collision, rollover, and collision with tunnel side walls are very easy to occur in horizontal and vertical combined road sections. In the existing research, the research on the horizontal and vertical combination is mainly focused on the ordinary highway, and there are few related researches on the horizontal and vertical combined road section in the special driving environment of the tunnel. In terms of the existing related technologies, mainly by enhancing the lighting brightness of the tunnel section, the driver can see that there is a horizontal and vertical combined road section ahead, which leads to high installation and operation costs, and cannot effectively reflect the change of the alignment of the horizontal and vertical combined road section of the tunnel, and lacks a relatively complete solution. Therefore, a safe, effective and economical line-of-sight guidance system is urgently needed for the horizontal and vertical combined road sections of tunnels with long distances.
