1. A method for determining and communicating shortest elapsed time route information to users, comprising the steps ofindividually and directly monitoring instant rates of travel on multiple route segments interconnecting various possible origins and destinations by sensor means located on the respective route segments;

  • transferring the instant rates of travel for each of the multiple route segments to a central processor;

    receiving information of desired origin and destination combinations in the central processor from different users;

    calculating in the central processor the route segment or combination of route segments providing a shortest elapsed time route between each origin-destination combination; and

    transmitting information of the shortest elapsed time routes for the origin-destination combinations from the central processor to the respective users whereupon route selection by the central processor is based on an accurate comparison of instant rates of travel along the respective route segments and each user receives specific information from the central processor as to the combination of route segments providing the shortest elapsed time route between the origin and destination for that user.
