Highway tunnel group travel reminding system

Abstract

The invention relates to the technical field of highway tunnel traffic safety. The invention particularly relates to a highway tunnel group travel reminding system. The system comprises a tunnel groupperspective pattern module, a tunnel relative distance pattern module, a transverse information module and a vertical information module, the positions of a tunnel group perspective pattern module, atunnel relative distance pattern module, a transverse information module and a vertical information module are combined; a tunnel group forecast sign, a tunnel entrance indication sign, a tunnel entrance distance sign, a tunnel exit indication sign, a tunnel exit distance sign and a tunnel group end sign are formed; a tunnel group forecast sign, a tunnel entrance indication sign, a tunnel entrance distance sign, a tunnel exit indication sign, a tunnel exit distance sign and a tunnel group end sign are arranged; the highway tunnel group journey reminding system is composed of a tunnel group front sign combination, a tunnel exit front sign combination, a tunnel sign combination and a tunnel group rear sign combination.

Description

technical field [0001] The invention relates to the technical field of road tunnel traffic safety, in particular to a road tunnel group travel reminder system. Background technique [0002] With the rapid development of the social economy and the deepening of the traffic construction process, the construction of expressways is rapidly extending to the mountainous areas in the central and western regions. Most expressways pass through the mountains and the ratio of bridges and tunnels is high. The bridge-tunnel ratio of a large number of newly built and planned mountainous expressways is as high as 70%, and they often appear in the form of continuous tunnel groups and bridge-tunnel connections. The risk in terms of operational safety is much higher than that of other road sections. [0003] On the basis of the "black hole effect" and "white hole effect" visual characteristics of individual tunnels in the tunnel group road section, its unique visual problems are: due to the sh...

AI Technical Summary

Problems solved by technology

Neither of them can effectively meet the driver's demand for predictable travel information.

[0010] In general, due to the poor visual characteristics of the road sections of the tunnel group and the lack of travel reminders and location reminders in the tunnel group in the current traffic safety design of the tunnel group, road traffic safety urgently needs a travel reminder system suitable for highway tunnel groups
