With the rapid increase of economy, roads as a means of transportation have reached their limits in the big cities in China. Traffic jams, environmental problems caused by transportation vehicles, lower transport efficiency, and the city logistic distribution bottleneck of E-Commerce are becoming the main problems faced with the government in every city in China. For example, in Beijing-the capital of P. R. China, the freight transportation volume has increased by 15% per year in the last 10 years. The number of private car has reached 2,000,000 in 2003. The traffic saturation has reached or even in excess of 100 percent in the most main roads in Beijing. As a result of these causes, the average traffic speed has been reduced by 50 percent over those 10 years ago, and is reducing by 2 km/year in the urban area. So an Underground Freight Transportation Network through Pipeline would be a sustainable way to deal with the city syndrome in Beijing. In this paper, the authors introduce firstly the basic concept of urban underground freight transportation system by pipeline/tube and its history and its research status. Furthermore, the necessity, urgency and the technical feasibility to develop this system in Beijing are discussed in detail. As the main body of this paper, the authors put forward a brief plan to build an underground freight transportation network system through pipeline in Beijing. The transportation pipeline network is planned beneath the main traffic roads and some distribution terminals/stations are planned along the transportation pipeline to distribute the goods to the consumers. In addition, the evaluations of the network, the analysis of the potential capacity of the system, the underground pipeline construction methodology and some key problems to be considered firstly to build this system are also included in this paper.
