The long-term trends of urbanization suggest: not only have more cities formed, but the leading metropolises have grown larger, with a number of peripheral subcenters developing over time. Conventional models of urban growth are limited, in that commuting cost and congestion eventually result in decreasing returns in a monocentric city as population becomes very large. We construct a general-eq...

This paper documents how one Department of Recreation in a large city underwent a planned change effort which transformed some 200 site managers into active community organizers. Based on the philosophy of a very dynamic new commissioner (a former community organizer), city employees enhanced local civic participation and forged a partnership between the public and private sectors as well as wi...

Visualization of large urban complexes on the web is highly demanding task both from the networking and computational point of view. The whole threedimensional model of a city is mostly too big to be downloaded in a reasonable time and to be stored in a memory of commonly used computers. This paper presents a scaleable approach for subdividing an urban model into smaller parts. Dynamic loading ...

Exploring an ever-dynamic, often-struggling city.

This data brief describes data collected in Cali, Colombia about the economic dynamic and socioeconomic conditions of street vendors in the city. The study was conducted between 2014 and 2016 in two populated sites in terms of formal and informal commerce in the city. We present the methodology followed in the study, location of street vending sites and type of data collected to approximate to ...

Interfaces to mobile information access devices need to allow users to interact using whichever mode or combination of modes are most appropriate, given their user preference, task at hand, and physical and social environment. This paper describes a multimodal application architecture which facilitates rapid prototyping of flexible nextgeneration multimodal interfaces. Our sample application MA...

Managing and modelling urban growth is a multi-faceted problem. Cities are now recognised as complex systems through which non-linear and dynamic processes, emergence and self-organisation occur. The design of a system that can handle these complexities is a challenging prospect. This paper presents an urban planning tool for the city of Riyadh, Saudi Arabia. At the core of the system is a Fuzz...
