Localization and transportation

We present a control strategy for localization and attenuation of disturbances in transportation systems. Sudden and large disturbances in a transportation network can lead to the creation and propagation of shock waves which spread throughout the system causing jams and decreasing system throughput. By considering the Cell Transmission Model of traffic flow, we design a minimum-energy controller that exploits inter-vehicle communication to localize shock waves to small sections of the highway and attenuate them within a specified period of time.

The control design is illustrated through simulations on realistic data from the I-210 highway in California.

On the basis of data on dynamics of freight traffics in the region and also additional socioeconomic indexes (the output, population, a gross regional product, volume of transportations on means of transport, etc.) it is offered to organize the system of the transport and logistics centers in the Far East. The calculations made it possible to identify nine points of efficient placement of logistics centers.

It is proposed to create a three-level system of logistics centers: federal, regional and local. Levels are divided depending on the importance in the overall transport system.
