This article adopts a family of surrogatebased optimization approaches to approximate the response surface for the transportation simulation input– output mapping and search for the optimal toll charges in a transportation network. The computational effort can thus be significantly reduced for the expensive-toevaluate optimization problem. Meanwhile, the random noise that always occurs through ...

Networks often possess mesoscale structures, and studying them can yield insights into both structure and function. It is most common to study community structure, but numerous other types of mesoscale structures also exist. In this paper, we examine core-periphery structures based on both density and transport. In such structures, core network components are well-connected both among themselve...

It has been recently shown that a macroscopic fundamental diagram (MFD) linking spacemean network flow, density and speed exists in the urban transportation networks under some conditions. An MFD is further well defined if the network is homogeneous with links of similar properties. This collective behavior concept can also be utilized to introduce simple control strategies to improve mobility ...

1 URBAN TRAFFIC DATA MINING The development of Intelligent Transportation Systems and the diffusion of urban traffic control and monitoring by Autonomous Agents have created very large databases of realtime and historic traffic data. Therefore, data mining approaches are necessary to design effective Decision Support Systems for traffic management and user information generation. In particular,...

The urban transportation network is made up of vehicles in motion, dynamic static and moving obstacles. These obstacles block the path of the moving vehicles thereby causing traffic jam. Thus it is important to model the network explicitly and to describe the movement of the vehicle and obstacles relative to the transportation network. In this study the researchers have addressed the : (i) prob...

There are many evident that people are more interested in walking in attractive urban spaces and inappropriate physical and psychological condition can reduce their presence in a remarkable amount. The current research investigates the influence of physical design and psychological elements and their criteria on selective physical activity and specifically walking in urban public spaces. Howeve...

Urban transportation systems grow over time as city populations grow and move and their transportation needs evolve. Typical network growth models, such as preferential attachment, grow the network node by node whereas rail systems grow by adding entire lines with all their nodes. The objective of this paper is to see if any canonical regular network forms capture the growth patterns of urban m...

Traffic networks and communication networks, the two integral parts of urban infrastructure, have many common characteristics. For example, they both are carriers for transporting agents, as traffic network is a carrier for running vehicles and communication network for transmitting the information packages. Besides, in both networks, the transportation efficiency and congestion problems are cr...
