The authors present an integrated GIS tool, Accessibility Analyst, for accessibility analysis in urban transportation planning, built as an extension to the desktop GIS software package, ArcView. Accessibility Analyst incorporates a number of accessibility measures, ranging from catchment profile analysis to cumulative-opportunity measures, gravity-type measures, and utility-based measures, con...

I nrecent years there has been a noticeable shift away from the application of computer-based transportation modeling methods in smallto medium-sized urban areas. In many cases, this shift has resulted from a disenchantment with the complex modeling methodologies used in the late 1960s and early 1970s. The expense of such methods, in terms of data collection and computational costs, was simply ...

This paper discusses the evaluation of synergies that derive from the implementation of policy packages designed to promote the use of public transportation and limit traffic congestion in urban areas. In this study, we propose the application of a land-use and transportation integrated (LUTI) model to study the outcomes from the implementation of two policy packages. We apply the long-term str...

Recent results concerning the development and exploitation of wireless vehicle-to-vehicle and vehicle-to-infrastructure communications in future generation intelligent transportation systems are discussed, as well as simulation techniques and tools used to effectively model such systems. Specifically, new algorithms to disseminate information in vehicle-to-vehicle networks have been developed, ...

Many ant species displaying synanthropic behavior that have successfully dispersed in urban areas can cause problems in hospitals by acting as bacterial vectors. In this study, we encountered bacteria on ants collected at the Universidade Federal de Uberlândia hospital, in the campus and at households nearby. The ants were identified as Tapinoma melanocephalum (Fabricius) and Camponotus vittatu...

As the experiment area of two-oriented society in China, Changsha-Zhuzhou-Xiangtan urban agglomeration is required with high level of environment friendliness and resource saving on its transportation system. The transportation of this area has entered into the harmonized development stage of various transport modes and improved capacity and quality. But the green degree of its transportation s...

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...

Recently, two quantitative tools have emerged for predicting the health impacts of projects that change population physical activity: the Health Economic Assessment Tool (HEAT) and Dynamic Modeling for Health Impact Assessment (DYNAMO-HIA). HEAT has been used to support health impact assessments of transportation infrastructure projects, but DYNAMO-HIA has not been previously employed for this ...

The structure of transportation networks and the patterns of accessibility they give rise to are an important determinant of land prices, and hence urban spatial structure. While there is ample evidence on the cross-sectional relationship between location and land value (usually measured from the value of improved property), there is much less evidence available on the changes in this relations...

This paper describes an innovative transportation system based on non-polluting autonomous vehicles. The proposed solution lies between high-speed outdoor moving walks and low-speed urban cars platooning. It integrates the service modes and advantages of both, while avoiding their main drawback, which are respectively the lack of scalability and the usage of traditional automobiles. The present...
