In The New Science of Cities , Michael Batty suggests that to understand cities we must view them not simply as places in space but as systems of networks and flows. Drawing on the complexity sciences, social physics, urban economics, transportation theory, regional science, and urban geography, and building on his own previous work, Batty seeks to introduce theories and methods that reveal the...

The recent adoption of ubiquitous computing technologies has enabled the capture of large amounts of spatio-temporal data about human motion. The digital footprints computed from these datasets provide complementary information for the study of social and human dynamics, with applications in urban planning and transportation. In this context, cell phones and cell phone networks, due to its perv...

Slime mould Physarum polycephalum builds up sophisticated networks to transport nutrients between distant part of its extended body. The slime mould’s protoplasmic network is optimised for maximum coverage of nutrients yet minimum energy spent on transportation of the intra-cellular material. In laboratory experiments with P. polycephalum we represent Canadian major urban areas with rolled oats...

Nowadays, the number of users relying on broadband wireless connectivity while riding public transportation vehicles is increasing significantly. One of the promising solutions is to deploy moving base stations on public transportation vehicles to form moving networks (MNs) to serve these vehicular users inside the vehicles. In this paper, we study the benefits and challenges in deploying MNs i...

1. introduction by the passage of the industrial revolution and entrance to the post-industrial era, the change and variety in the functions of capitalistic powers, ict revolution, and the speeding up of globalization after the 1960s have brought about renewal of the operational, spatial, and managerial structures of cities. in line with the mentioned changes, the structural changes resulted fr...

In China, rapid economic growth and increasing foreign direct investment (FDI) is the driving force for urbanization, and transformation of urban spatial structures and transportation. Frequent interactive economic activities among the neighboring cities reinforce the already spatially clustered cities. In this paper we tried to extract the key urban transportation characteristics of seventy ma...

Transportation planning models are typically used to estimate future traffic patterns, peak period traffic, travel time, and various environmental or other related traffic flow characteristics. Unfortunately, traffic safety is seldom, if ever, explicitly considered proactively during the transportation planning process. This omission is attributed to various factors, including the lack of avail...

Increasing pressures caused by negative consequences of transportation and traffic problems in major cities, have resulted many attempts towards improvement of planning and management of transportation systems, according to sustainability objectives. In this paper, a comprehensive model is developed using a system dynamics approach to evaluate sustainable urban transportation. This model includ...

Understanding network flows such as commuter traffic in large transportation networks is an ongoing challenge due to the complex nature of the transportation infrastructure and human mobility. Here we show a first-principles based method for traffic prediction using a cost-based generalization of the radiation model for human mobility, coupled with a cost-minimizing algorithm for efficient dist...

Transportation terminal is the key node in transport systems. Efficient terminals can improve operation of passenger transportation networks, adjust the layout of public transportation networks, provide a passenger guidance system, and regulate the development of commercial forms, as well as optimize the assembly and distribution of modern logistic modes, among others. This study aims to clarif...
