This
market package offers the user pre-trip route planning and turn-by-turn
route guidance services. Routes may be based on static information or
reflect real time network conditions. Unlike ATIS3 and ATIS4, where the
user equipment determines the route, the route determination functions
are performed in the Information Service Provider Subsystem in this market
package. This approach simplifies the user equipment requirements and
can provide the infrastructure better information on which to predict
future traffic. The package includes two way data communications and optionally
also equips the vehicle with the databases, location determination capability,
and display technology to support turn by turn route guidance.
