Abstract


Trunk highway is an important part of China 's highway network , played a crucial role in the national transportation economy , but the security situation of the trunk road has been worrying trunk highway traffic safety study is significant . Factors affecting road safety is complex , it is a complete accident by people , vehicles, roads and other factors chain . Difficult for any accident due on certain single factor , but the running speed is the driver 's psychological and behavioral aspects of road geometric alignment and road environment in the final results and the external manifestations of the car , through the this comprehensive reaction results in effective evaluation of the road safety situation . The papers to the Gansu Provincial Department of Communications Science and Technology project in Gansu Province trunk highway safety evaluation and study \linear elements , especially from a qualitative point of view on the trunk highway running speed factors detailed analysis , and then based on the actual speed of the trunk road , through the theoretical regression analysis and experimental verification method to build a trunk highway trucks and passenger cars running speed the prediction model ; followed by comparative analysis of the proposed evaluation method suitable for the trunk highway established adjacent sections run speed \Finally, the test course , the combination of accident data , the research results in the specific applications herein , calculated from the running speed of each point of the road , and the road safety evaluation to verify the feasibility of the evaluation model .
