The method of path optimization based on fuzzy dynamic path weight

摘要

In order to meet the demands of dynamic path optimization for road-network real-time traffic information, the model of dynamic transportation network based on the fuzzy-genetic algorithm were constructed in this paper. Firstly, through the two-dimensional fuzzy design in the fuzzy logic toolbox of Matlab software, the real-time traffic flow parameters were transformed into crowdedness degree in the range of 0 to 1. Next, the dynamic network model was established by using graph theory. At last, the short circuit of driving scheme is generated after optimizing the dynamic network model using genetic algorithm. Taking the road information in Taiyuan as an example, the results show that the improved algorithm has the characteristics of good real time, dynamic and stability.
