Bidirectional flyover rotary intersection road surface guidance system

Abstract

The invention relates to the technical field of road traffic ancillary facilities, in particular to a bidirectional flyover rotary intersection road surface guidance system. The bidirectional flyover rotary intersection road surface guidance system comprises a plurality of advance sign boards which are arranged at each entrance carriageway of a rotary island, a plurality of bridge piers, a plurality of isolating piles, road edge colour which is smeared on the curbs on the two sides of each entrance carriageway of the rotary island, rotary island indicating signs which are arranged on the road surface of the rotary island, and arrow-shaped guide marking lines which are arranged on the side wall of the rotary island. According to the bidirectional flyover rotary intersection road surface guidance system, the guidance system is arranged at a plane rotary intersection to effectively stimulate the visual perception of a driver and help the driver to quickly match and judge the direction of an exit; engineering grade reflective film strips coat the outer surface of each advance sign board; when a headlamp of a vehicle irradiates the reflective film strips, the brightness of entrances, exits or the rotary island is effectively increased, the visibility of the driver to the sign boards is effectively improved, and the traffic efficiency and the traffic safety of an annular road surface are improved.

Description

technical field [0001] The invention relates to the technical field of road traffic auxiliary facilities, in particular to a two-way overpass roundabout road surface guidance system. Background technique [0002] At present, there are too many signboards in some roundabouts in our country, and there is no clear frame of reference. The discontinuous information, insufficient information or overload in the intersections will easily cause the driver to have a poor sense of direction at the roundabouts, easily dizzy, and induce unnecessary accidents. Detour, or even go the wrong way. At the same time, the separation of the traditional intersection sign (set in the roundabout) and the guide sign (set in front of the entrance of the roundabout) will easily lead to unsatisfactory visual forgetting effect of the driver. [0003] The current research on pavement sign information at roundabout intersections mainly focuses on the amount of sign information and the location of signs at...

Problems solved by technology

For example, in the international conference paper "Research on Limit Information Amount of Roundabout Guidance Signs Based on Driver Information Processing Model" by Tang Jianjuan and Dong Lu (The Eighth International Automobile Traffic Safety Academic Conference, 2010), the indoor simulation experiment was used to analyze the sign information. The relationship between volume and cognitive time, thus determining the limit information volume of roundabout signs; Chen Yan passed a large number of The indoor simulation experiment gives the suggested value of setting position of road intersection guide signs based on different driving speeds and sign information, which is suitable for different weather and light conditions. oral orientation
