Abstract

Vehicles (106) are equipped with two-way communication units (401) that communicate with roadside (114) and vehicular mounted two-way communication units to receive and/or exchange journey-related information. When approaching a geographic zone that does not support such services, a given vehicle (106) can receive at least a partial download of journey-related information concerning the second geographic zone (102) while still proximal to the entry border (107) for that zone (102). The download can be implemented wirelessly, through hard physical contact, or both. The download may also be at least partially concluded while traveling within the second geographic zone (102) through use of a second non-compatible wireless service such as wireless telephony.
