More Efficient Routes

UPS uses a form of geospatial technology in their "package flow technology" which helps (among other things) route deliveries every day. This $600 million software package has eliminated 29 million driving miles from the annual system, saving money and fuel, and improving the environment and local traffic situation. A key to this system has been the recognition that left-turns often require a minute of idling at the light.
