System and method for providing route guidance

The techniques described herein provide route guidance, based on an individual traveller's preferences, the type of vehicle, and various safety and other factors. For example, some embodiments of the present invention consider the amount of gas available in a gas-powered automobile in suggesting routes that pass near a gas station before the automobile is expected to run out of gas. Some embodiments of the present invention consider the amount of diesel fuel remaining in a diesel-powered automobile in suggesting routes that pass near a station selling diesel fuel before the automobile is expected to run out of gas. Some embodiments of the present invention consider the amount of charge available in the batteries of an electric powered automobile in suggesting routes that pass near an electric charging station before the automobile is expected to run out of charge. Some embodiments consider the condition of the roads in suggesting routes that avoid roads that are covered with ice, snow, potholes, etc. or are under construction.
