Abstract:

In order to meet the needs of the traffic management on road network reliability analysis, a concept of the traffic operation reliability was proposed. The time-segmenting reliability and the time-aggregating reliability, two characteristic parameters were constructed for the road network traffic operation reliability. The analysis method of the time-segmenting reliability of the road network between O and D was designed according to the minimal path set method. The analysis method of the time-aggregating reliability was designed using the global scanning method. The experimental results indicated that the proposed method can analyze the time-aggregating and time-segmenting reliabilities of the road network, can define the importance degree of the road segment and intersection according to their effects on the road network reliability, providing a basis for decision-making in the traffic management.
