COLLEGE OF ENGINEERING THE UNIVERSITY OF TEXAS AT AUSTIN Center for Transportation Research Suite 200 3208 Red River Austin, Texas 78705-2650 (512) 232-3100 FAX (512) 232-3153 MEMORANDUM To: The President From: Randy B. Machemehl, P.E. Standy washl Director, Center for Transportation Research Date: 24 January 2000 Fifty years from now technology will have contributed significantly to solving many of our year 2000 transportation problems. However, transport will remain a very significant part of the world economic system and problems will likewise remain. During the intervening five decades, today's urban commuter transportation problems will grow in severity until a public outcry causes legislators to provide increased funding. As the result of this new initiative, some of today's new technology will receive widespread implementation and new concepts will be developed. Driver information systems providing forecasts of travel times for alternative routes will become a part of all vehicles through both audio and visual in-vehicle systems. Urban traffic signal systems will be controlled by high-speed computers providing real time responses to traffic incidents and special event traffic demands. Automated highways which will relieve drivers of most driving tasks and provide increased capacities and much higher speeds will become available in many locations. Due to public concern over urban air quality problems, vehicles using alternative fuels and alternative propulsion systems will become much more common. However, fossil fuels will continue to provide a significant fraction of transportation system energy needs. Additionally, urban congestion and air quality problems will cause at least modest traveler behavior changes. Urban work travelers and employers will become much more willing to participate in flex time programs that will reduce pronounced AM and PM peak hour transport system demands. These same concerns will cause many auto drivers to seek mass transit as a means of serving many travel needs. Transit buses will be powered by hybrid propulsion systems including regenerative braking with flywheel energy storage systems and active electronic suspension systems dramatically reducing energy consumption, emissions, and improving ride quality. Transit users will have wristwatch size transponders that tell them exactly when their bus or train will arrive at their intended boarding location. 1
