Restructuring The Automobile/highway System For Lean Vehicles: The Scaled Precedence Activity Network (SPAN) Approach

This paper studies relative time savings between vehicles unequipped and equipped with route guidance and navigation systems. In particular, the report investigates to what extent relative travel time savings decrease as the percentage of equipped vehicles increases. In addition, some other potential services that can be provided by navigation systems are identified. The report focuses on benefits for commuters, although some results are applicable for other users.
