Modeling and Measuring the Road Network Reliability

Road network reliability has attracted numerous interests from nowaday academic researchers and practitioners due to its vital significance to industrial operation,economical development and people's daily life.This paper systemically reviewed the updated research progresses of the road network reliability internationally and nationally regarding the various indices,models and frequently used approaches.In order to evaluate uncertainty of the road network,a stochastic network equilibrium model(SNE) was proposed,in which travel times are random variables.Finally,an improved reliability model was formulated based on the reserve network capacity and the SNE model.
