Environmental effects of road transport telematics

Road transport telematics have developed greatly during the last few years. Telematics have not been developed specifically for environmental reasons, but to improve efficiency, cost and safety of transportation chain. The environmental impact of telematics always varies by the location and the technology in use. In most cases environmental benefits can only be estimated by the use of field tests, analysis and modeling. However, there are only a few models developed solely for the needs of telematics. Completed evaluations generally show telematics applications to be environmentally friendly. These positive impacts often result from smoother and more efficient flows in the transportation system. Some applications have both positive and negative environmental impacts. This study presents estimates on the impacts of the use of telematic applications in Finland. The extent of these impacts is also evaluated. It is estimated that driver communications, vehicle navigation and route guidance, intelligent idle stop systems, route and transportation planning, on-board diagnostics and dynamic signal control would be the most beneficial applications for improving the air quality in Finland. In case of accident the hazardous cargo monitoring system can help to mitigate the local emissions to air and soil. Many applications bring environmental benefits, but the use of these technologies in Finland can be argued. The implementation of many technologies is limited by transport volumes. Some applications may be beneficial in passenger vehicles, but the relatively small number of commercial vehicles in Finland lessens the environmental benefits. Many telematic applications were developed for passenger cars or public transport. Implementing these technologies in commercial vehicle operations is still under way.
