Claim 12

The method of claim 10 further comprising the step of collecting historical real time data in the central processor to determine normal time variations for the instant rates of travel for the multiple route segments and employing the historical real time data in calculating the shortest elapsed time route between each origin-destination combination.

Claim 13

The method of claim 1 further comprising the step of monitoring instant rates of travel at a plurality of locations along each route segment in order to provide a more accurate calculation of the shortest elapsed time routes for the origin-destination combinations.

Claim 14

Apparatus for determining and communicating shortest elapsed time route information to users, comprising sensor means for individually monitoring instant rates of travel on multiple route segments interconnecting various possible origins and destinations, the sensor means being located on the respective route segments; means for transferring the instant rates of travel for each of the multiple route segments to a central processor; means for receiving information of desired origin and destination combinations in the central processor from different users; means in the central processor for calculating the route segment or combination of route segments providing a shortest elapsed time route between each origin-destination combination; and means for transmitting information of the shortest elapsed time routes for the origin-destination-combinations from the central processor to the respective users, whereupon route selection is based on an accurate reflection 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 between the origin and destination for that user.

Claim 15

Apparatus for determining and communicating shortest elapsed time route information to users, comprising sensor means for individually monitoring instant rates of travel on multiple route segments interconnecting various possible origins and destinations, the sensor means being located on the respective route segments; means for transferring the instant rates of travel for each of the multiple route segments to a central processor; means for receiving information of desired origin and destination combinations in the central processor from different users; means in the central processor for calculating the route segment or combination of route segments providing a shortest elapsed time route between each origin-destination combination; and means for transmitting information of the shortest elapsed time routes for the origin-destination-combinations from the central processor to the respective users, whereupon route selection is based on an accurate reflection 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 between the origin and destination for that user.

Claim 16
