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 national significance of urban transit has been the subject of much debate in recent years. To place the various arguments in perspective, this article offers a brief overview of major developments in urban transit, particularly focusing on the effects of federal assistance, during the last twenty years.

Recently, new approaches with commercial high-resolution satellite imagery in the engineering application domains have been attempted. Among them, uses of remotely sensed imagery linked with GIS-T (Geographic Information Systems for Transportation) or transportation geography are regarded as one of prospecting issues. As the matter of facts, most transportation applications are needed real-time...

This paper reports on the first stages of our work to build an integrated decision-support tool to analyse sustainable transportation systems. A preliminary description of the application domain is presented and some modelling issues are discussed. An artificial transportation framework is conceptualized on the basis of three important subsystems, namely the real world, the virtual domain and t...

This paper describes the urban design of the digital city called AlphaWorld. AlphaWorld is a digital community created in 1995 and accessed daily through the internet by thousands of users. Unlike other digital communities, AlphaWorld’s users may also settle land and construct objects within the world. The design and content of these constructions are determined autonomously, and the cumulative...

Objective: To improve the reliability of complex urban public transportation network. Methods: Establishing the reliability evaluation system of urban public transportation network. Process: The paper introduces the development of urban traffic construction, describes the characteristic parameters of complex networks, and establishes the model of the reliability evaluation index system of compl...

This paper presents an overview of the Future Urban Mobility programme of the Singapore-MIT Alliance for Research and Technology (SMART). Through this programme, MIT is establishing a research centre in Singapore with the mission to support sustainability and improve transportation system performance through innovations in infrastructure, technology, operations and policy. Two key areas of rese...

Patterns of land use and available transportation systems play a critical role in determining the economic vitality, livability, and sustainability of urban areas. Transportation interacts strongly with land use. For example, automobile-oriented development induces demand for more roads and parking (which in turn induces more automobile-oriented development), while compact, pedestrian-friendly ...

This chapter provides an introduction to urban simulation, which we interpret broadly to mean operational models that attempt to represent dynamic processes and interactions of urban development and transportation. Its intent is to provide the reader with a reasonable understanding of the context and objectives for urban simulation modelling within metropolitan areas in the United States, the l...

We give a model for the description of an urban transportation network and we consider the related optimization problem which consists in finding the desing of the network which has the best transportation performances. This will be done by introducing, for every admissible network, a suitable metric space with a distance that inserted into the Monge-Kantorovich cost functional provides the cri...
