| Abstract: | Travel network structure optimization is an effective measure to ease the ur- ban traffic congestion. Trip network optimization algorithm is built based on improving the degree of match between trip network and road network. Considering the bi-level characteristics of urban road traffic network,the matching degree index on bi-level net- work was proposed. The trip network optimization algorithm considering the matching degree index is established based on edge deletion. The experimental analysis shows that the algorithm can optimize the structure of trip network and alleviate traffic congestion effectively. |
