1. A computer-implemented method of activating an on-board warning in a vehicle, comprising:
- automatically determining a location of the vehicle;
obtaining, from a facility remotely located from the vehicle, data relating to environmental road conditions proximate to the vehicle, responsive to said automatically determining the location of the vehicle; and
activating the on-board warning responsive to the data.

Abstract
A system for automatic detection of road conditions reduces emissions from vehicles by determining whether proposed routes may be less efficient due to weather conditions. In one aspect, the system chooses routes not only based on overall distance to travel, but also based weather conditions. The determination is made by information received from various sources, including other vehicles and roadside sensors. In-vehicle warnings are also provided by combining data from in-vehicle sensors with data from other sources, such as conditions currently sensed at upcoming locations and historical and forecast weather data.
