Traffic Incident Situation Evaluation Based on Road Network Reliability of Invulnerability

In the frame of the project «Criteria of traffic control quality and effectiveness in Russian Federation» the Transportation Laboratory of ISTU was invoved into elaboration of network performance appraisal. Two alternative congestion measures were considered. The ratio of peak period to free flow travel times was proposed as a test criterion of urban highway network reliability.

Extent Of Damage

In view of the phenomenon that the affected area is broader, more severe losses and more difficult to relief in the urban agglomeration after major natural disasters,it is proposed that transport system reliability calculation method which based on BP neural network model.First of all,analyze the urban transport system network after a disaster, using the weight contribution rate analysis method to extract the key nodes in the network; Second, re-integrating the extracted nodes and establishing a new road network model which based on BP neural network;Then, using the cut set algorithm computing network reliability, and combined with the extent of damage of the road network after a disaster, putting forward the calculation method of urban agglomeration road network reliability after disasters; Finally, for example as changsha-zhuzhou-xiangtan urban agglomeration, examining the authenticity of the method.

This paper conducts an in-depth research on applications reliability in highway network planning and optimization of construction sequence. It introduces the concept of reliability to the layout of the importance of the road network node and establishes a fairly comprehensive theoretical method of highway network planning based on the reliability from the aspects of the road network layout, evaluation, and construction sequence arrangements. Case study illustrates the proposed layout optimization method has achieved satisfactory results in the road network reliability analysis, displaying strong practical promotional value.
