Environmental-Friendly Navigation: Technology Description and Field Operational Testing Plan

This paper describes one measure that drivers can take to reduce their travel costs and emissions: Environmental-Friendly Navigation (EFNav), whose key innovation is the integration of current navigation technology with sophisticated vehicle energy and emission models. EFNav provides the ability for a driver to not only have a choice of selecting a shortest-distance or shortest-duration route, but also a route that minimizes the fuel consumed and/or pollutant emissions for a particular trip. So far, EFNav has been successfully developed and tested on a freeway-only network. The authors describe a new research initiative in which EFNav is being enhanced by expanding to include surface streets and migrating to an on-board prototype system. This system is currently being tested in the San Francisco Bay area. With this network data expansion, EFNav will be able to guide a driver through more route choices. For instance, for some trips the most environmentally-friendly route could be entirely on arterials.
