Optimal path search on the degradable road network considering the reliability
Xia Yun-lon · Journal of Transport Science and Engineering · 2013
Random and reliability of the travel time in the degradable road network will more seriously influence the choice of the travel path,so the optimal path choice model is built in the degradable road network.The mean value model and the reliability model on the path travel time is set up based on BPR model which is a model on the link travel time in the degradable road network.Taking into account the factors of reliability and travel time,a bi-objective path selection model is devised.Using the improved ant colony algorithm,the bi-objective weighted model is solved.The case shows that the improved algorithm can supply quickly the reliable path.
