Abstract:
The idea of vehicle-highway communications sufficient to assume driving functions for the driver is not new. Researchers have articulated both its value and feasibility for several decades; and military and vehicle manufacturer test facility developments have proven the concept's viability. As mounting congestion conflicts with environmental constraints, the Automated Highway System (AHS) promise of doubling our existing highway system's capacity is worth investigating. The Automated Highway System (AHS) concept defines a new relationship between vehicles and the highway infrastructure. AHS will use: control technologies that shift driving functions from the driver/operator to the vehicle; and, communications technologies to recognize and react to the external infrastructure's real-time traffic conditions. The AHS concept combines on-board vehicle "intelligence" with a range of "intelligent technologies" installed onto the existing highway infrastructure. The vehicles will be dual mode vehicles that can operate on both AHS and non-AHS lanes, including automobiles, buses, and trucks. The infrastructure intelligence can be allocated across a spectrum, that on the one end is highly dependent upon vehicle intelligence to the other end where the intelligence is concentrated on infrastructure. 8 p.
