Layout Planning of Container Piggyback Transport Stations Based on Road-Railway Intermodal Transportation

In response to the call of Chinese government, accelerate the development of multimodal transport system. This article aims to the key layout planning problem as study object, takes container piggyback transportation as the background and bases on the idea of hub-and-spoke network. Aiming at minimizing the total cost of network operation, establishes the location model of piggyback transport node based on the hub-and-spoke network, designs the heuristic algorithm and combines the current regional cargo traffic and transportation network status in China and then calculate the transportation network hub location scheme and the total operating cost of the hybrid hub-and-spoke network, compared with the pure-axis spoke network and the shortest-circuit network.
