Study On The Optimization And Design Of Highway Traffic Engineering Facilities

The optimization of highway traffic engineering facilities system helps to reduce the probability of road traffic accidents,and also helps to reduce the severity of accidents.At the same time,to eliminate all kinds of interference factors,the optimization of the highway traffic engineering facilities system has an important role in improving the service level of the highway,providing the line of sight guidance for the driver and improving the landscape along the highway,so it can improve the service level of the highway.At the same time,it can also effectively solve highway traffic engineering problems,and is conducive to promoting road traffic safety.First of all,the paper introduces the research results of traffic engineering facilities at home and abroad,and then analyzes the system of traffic engineering facilities,and the system composition and environmental factors(such as vehicle status,driver status,weather status,laws and regulations and implementation degree).And the basic characteristics of traffic engineering facilities(mainly on the feasibility and necessity of the optimization of the highway system design),through the above analysis,the road traffic engineering facilities can have a simple understanding,and the later can better optimize the design of traffic engineering facilities.Next,we optimize the design of the intersection,and analyze the existing problems of traffic engineering facilities at the intersection.According to the problem,we use the relevant theory and expert experience to optimize the intersection angle,radius and intersection channelization.The control modes of some lanes and intersections have been optimized to improve the safety of road intersections.At last,taking the Tang Cao highway as an example,some parts of the road are optimized and the traffic signs are optimized by the established recognition model so that the driver can get the road condition with the shortest time and the highest efficiency,which is beneficial to the improvement of road safety.At the same time,the optimization design of road isolation facilities,intermediate protective facilities and road separation facilities is also carried out.The research results of this paper are of great significance for improving road safety and beautifying road landscape.
