APPARATUS AND METHOD FOR PROVIDING TRAFFIC INFORMATION
First Claim
1. A method for providing traffic information, the method comprising:
- for each segment of a route between an origin point and a destination point,performing a time-dependent journey planning calculation, based on a time during which a vehicle is predicted to be travelling through the segment, to produce a segment result;
forming at least one route result, the at least one route result being formed based on a plurality of the segment results;
storing the at least one route result in a digital storage means; and
accessing the rapid access means for use in responding to a user request for traffic information for a journey between the origin point and the destination point.

Abstract
A system and method for providing traffic information provides for each segment of a route between an origin point and a destination point, a time-dependent journey planning calculation is performed, based on a time during which a vehicle is predicted to be traveling through the segment, to produce a segment result; a route result is formed, based on a plurality of the segment results, and stored for use in responding to a user request for traffic information. A portion of a recommended most economic route between an origin point and a destination point can be pre-determined and stored. With reference to a first network of geographical boundaries and second network of digital map nodes, a recommended most economic route between an origin point and a destination point can be determined and transmitted to a user.

18. A system for providing traffic information, the system comprising:
-
a route segment processor for performing, for each segment of a route between an origin point and a destination point, a time-dependent journey planning calculation based on a time during which a vehicle is predicted to be travelling through the segment, to produce a segment result; a route result formation means for forming at least one route result, the at least one route result being formed based on a plurality of the segment results; a rapid access means, in a digital storage means, for storing the at least one route result; and a user request processor for accessing the rapid access means for use in responding to a user request for traffic information for a journey between the origin point and the destination point. - View Dependent Claims (19, 20)
