Analysis on the Importance of the Road Design in Urban Traffic Safety

Traffic engineering,as a systematic project,is the core part of the road construction.And the road design is on the dominant position of the traffic engineering,and its design principle is to improve the performance and safety of roads.The line position settings should be done as a whole according to the road terrain and topography.And at the same time,the geographical position and safety performance of the bridge and culvert should be further confirmed based on the geometric alignment in order to make the whole road design more safe and reasonable.
