High unloaded ratioof trucks is one of the key factors that incur high costs of mail transportation in China's postal network. How to reduce unnecessary deadhead kilometers of trucks is worthy of being researched. In this paper, we take heterogeneous trucks and facility capacity into consideration of optimizing the postal express line network using Rendezvous driving pattern of trucks. A mixed integer non-linear programming model is built and a corresponding mixed genetic algorithm is developed to solve the model. A numerical simulation is also designed to verify the validity of the model and the algorithm developed in this research. Through a comparison of Rendezvous and direct travel mode, some insights of Rendezvous are presented
