Photoacoustic detection and monitoring of pollutant gases from urban public transport

Urban Public Transport Challenges

This paper focuses on a number of challenges faced by the public transport industry and the prospects for resolution. Many of the issues are often shrouded in ideology, politics and prejudices that typically cloud the real merits of a solution. We argue that public transport is increasingly a niche provider of land passenger transport services, which if positioned and managed better will be cap...

Urban Pollutant Transport and Infiltration into Buildings Using Perfluorocarbon Tracers

People spend the majority of their time indoors and therefore the quality of indoor air is worthy of investigation; indoor air quality is affected by indoor sources of pollutants and from pollutants entering buildings from outdoors. In this study, unique perfluorocarbon tracers were released in five experiments at a 100 m and ~2 km distance from a large university building in Manchester, UK and...

Service Reliability and Urban Public Transport Design

Urban sustainable development from public participation in urban management

Urban management in any context has a different economic, social and political structure, which is in harmony with the existing models of organization. In spite of these differences, in order to reach a sustainable urban development, several different conferences should be referred to. In the “Brundtland Commission 1987” about urban sustainable development these definitions have been given: “pr...

Eddy covariance flux measurements of pollutant gases in urban Mexico City

Eddy covariance (EC) flux measurements of the atmosphere/surface exchange of gases over an urban area are a direct way to improve and evaluate emissions inventories, and, in turn, to better understand urban atmospheric chemistry and the role that cities play in regional and global chemical cycles. As part of the MCMA-2003 study, we demonstrated the feasibility of using eddy covariance technique...
