Environmental factors in intelligent transport systems

Increased car use has highlighted the problem of congestion, not only as a threat to economic growth but also as a substantial contributor to poor air quality, noise, health risk and global warming. This paper draws on the literature to try to heighten the awareness of the issues regarding the environment and health impacts of traffic related pollution. It shows how vehicle technologies and intelligent transport systems can play an important role in addressing environmental problems in urban areas. This review aims to stimulate interest that will hopefully result in a change in perspective so that intelligent transport system implementation is considered, not simply as a tool to reduce delays and lower the risk of accident, but also, through integration of technologies, to deliver good air quality and quieter soundscapes, and thus better quality of life and long-term sustainability of towns and cities.
