Abstract
The report presents a review of the state- of- the- art of in- vehicle navigation and mobile communications techniques and equipment. A features matrix is used to classify the equipment in terms of infrastructure relationship, navigation technology, system function, etc. Human factors implications are also addressed. The primary functions likely to be provided in future systems (eg., road map display, en- route conditions, vehicle /cargo position tracking) and their specific features are grouped under five application areas: travel advisory, fleet management, traffic management, mobile office, occupant activities and vehicle control.
