Road network traffic operation reliability analysis based on detected data
Ande Chang · Journal of Jilin University · 2011
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.
