1. A route planning system for road vehicles, comprising:

  • a ride quality database representing a plurality of road segments according to geographic coordinates;

    an agent coupled to the ride quality database and adapted to be coupled to a data network,wherein the agent is configured to receive ride quality data via the data network from a plurality of vehicles traversing the road segments and to determine a composite ride quality index for each road segment according to the received ride quality data,wherein the ride quality data comprises primary ride and secondary ride,wherein primary ride corresponds to ride quality at a frequency of about 1-2 Hz, and secondary ride corresponds to ride quality at a frequency of about 10 Hz,wherein the ride quality data and the composite ride quality indices for each road segment are stored in the ride quality database in association with the respective road segment, andwherein the agent is configured to receive routing requests specifying a desired ride quality and to respond to the routing requests by retrieving road segments and the corresponding ride quality indices in response to the routing requests; and

    a route planner calculating potential routes and respective route indices by combining the ride quality indicies of the road segments in each potential route.
