Abstract : *(250~1000 words)

Route planning and optimal speed design is one of the main challenges in the development of river-sea direct transport and combined transport in China. Han-shen line jianghai direct routes opened, Hanhai 1, 2, 3 and 7 container ship putting-in-service proactively, opened a new era of container liner directly from Wuhan Jingkai port to Shanghai, and the most advanced and the largest loading capacity of inland river maiden voyage "Hanhai No.5", marks the wuhan 5 "Hanhai" series of jianghai direct container ship all put into operation.  Announced Wuhan Xingang thousand box class fleet formally formed.  In view of the influencing factors, scholars at home and abroad successively put forward the route research problems from waiting time, coordination difficulty, stable shift time and so on, and further put forward the solutions such as route planning, optimal speed design, constantly strengthening market promotion, competing for high-quality cargo sources, and improving ship stowage rate.  
Standing in the perspective of "Hanhai No.5", in order to cross the deployment of Hanhai No.5 and other "Hanhai" series of shipping schedule, considering the actual operation, to improve ship voyage and running time as much as possible, avoid the ship ran aground, or hit the bridge accidents, research on "Hanhai No.5" from yangluo port to the yangshan port upward, special routes, namely the sea into the river from wuhan yangluo port. Based on the route model of inland river network between Jiujiang port, Taicang port, Waigaoqiao port and Yangshan port, a* algorithm is used to analyze and summarize the existing route planning, and proposed a better route and optimal speed design.  The results show that the a* algorithm can optimize the route over the bridge and the route through different grades, and can be well applied to the route planning of inland river network.  The optimization suggestions based on the above research conclusions are helpful for Hubei province to comprehensively utilize the Resources of the Yangtze River, and assist "Hanhai No.5" to play more benefits and reduce costs while increasing the loading capacity.
