Title: POINT OF VIEW: INTELLIGENT VEHICLE-HIGHWAY SYSTEMS: BOON OR BOONDOGGLE?

Digital Copy: Availability: Find a library where document is available Abstract: This article discusses the costs and alternatives to intelligent vehicle highway system (IVHS) technology. The high cost of IVHS implementation, as well as its maintenance, cannot be ignored or explained away by such vague statements as "Installation, operational, and maintenance costs...can be offset by user fees". There are also the indirect costs. IVHS promises to accelerate a longstanding inequity in transportation--the tendency of the highway system to lock out users of nonmotorized transport modes. In addition, many drivers are already uncomfortable or nervous behind the wheel, and drivers fiddling with onboard computers and reading information displays while driving will not enhance safety. There is also the myth of congestion relief. Travel demand is not a static commodity; it responds dynamically to the supply of capacity. Increasing capacity tends to relieve congestion in the short term but soon stimulates additional travel demand. Even proponents of IVHS recognize that it would produce marginal improvements to traffic flow (15%), fuel consumption (3-12%), and pollution (8-15%). The alternatives to IVHS, including travel by foot, bicycle, public transit, and high-occupancy vehicles, and changing land-use patterns are the only sustainable solution to reduce automobile transportation demand.
