Township road with road edge barrier in mountainous area

Abstract

A township road with road edge barrier in mountainous area relates to the field of lane design, especially the design of carriageway in rural lane. As township roads are relatively narrow and mostly built in high mountains and lofty hills, one vehicle is unable to give another the right of way, and is prone to having an accident. In order to reduce the accidents during back off of vehicles on a township road and enhance driving safety, the invention designs the township road with road edge barrier in mountainous area. A technical scheme is as below: two sides of the carriageway are provided with road edge barriers in arc surface with preferable curvature radius R of 30cm; and lay-by positions are arranged at wide spaces at intervals. The edge of the curved surface is preferably provided with a rectangular barrier of 20cm wide and 50cm high; and the rectangular barrier, the arc surface and the carriageway are integrated into a whole. The invention has the following beneficial effects: barriers at road edges can effectively prevent the wheels from slipping off the road, so as to reduce traffic accidents; as the vehicle giving the way performs a slow speed, the arc barriers facilitate guiding the vehicle to keep a right marching direction; and the lay-by positions are helpful to increase the efficiency of the vehicles.

Description

technical field [0001] The invention relates to the field of lane design, in particular to the design of lanes of country lanes. Background technique [0002] Township roads, that is, rural roads, generally have a width of about 3M, which is the guarantee for the villages to reach various places. The construction materials are black asphalt or cement roads, and the thickness is about 8CM. Most of the township roads are built at the junction of each village. [0003] Due to the narrowness of the rural roads, it is impossible to realize the wrong vehicle, and most of the rural roads are built between high mountains, the geological stability is poor, and there are many risk factors; Position, maneuverability and visibility when reversing are much worse than when driving forward, prone to accidents. Contents of the invention [0004] In order to reduce accidents caused by reversing vehicles on rural roads in mountainous areas and enhance the safety of driving, the present inv...
