Abstract

The invention discloses a method for optimally setting expressway traffic safety facilities, which comprises the following steps of: determining key sections of the optimally-set expressway traffic safety facilities; optimally setting the safety facilities of sharp bend, inflection and continuous curve road sections; optimally setting the safety facilities of a bridge head combined with a sharp curve section; optimally setting the safety facilities of a long and steep longitudinal slope section; optimally setting an emergency lane; optimally setting the safety facilities of a long straight line section; optimally setting the safety facilities of a poor sight distance section; optimally setting the safety facilities of roads and bridges, and roads and tunnels transition sections; and optimally setting the safety facilities of a vertical crossing section. In the method, requirements of a driver on safety, quickness, high efficiency and comfortableness are fully met according to the influence of road conditions such as a plane and vertical section line, a pavement structure, roadbed and side slopes, bridges and tunnels, an overhead crossing project of the expressway on driving safety.

Description

technical field [0001] The present invention relates to a method for setting up facilities in the field of traffic safety, in particular to a method for optimally setting up highway traffic safety facilities. To achieve the most reasonable and safest setting of the entire traffic safety facility system. Background technique [0002] Traffic safety facilities are an important part of expressways, which play an important role in giving full play to the functions of expressways and ensuring driving safety. At present, there are still many deficiencies in the application of expressway safety facilities, especially in terms of the number, location and form. Problems that exist in the disconnection of actual road conditions, such as: insufficient anti-collision capability of guardrails on continuous downhill road sections; unreasonable position and form of marking markings; imperfect variable speed signs and lane utilization signs; road bridges, bridges and tunnels and their trans...
