Abstract: Many regional agencies model travel demand without feeding assigned travel times back to the trip distribution step. This method saves time and money but is likely to be biased in favor of build alternatives because it ...

Abstract: The automation of urban freeways is a major feature of the new surface transportation act. Reducing freeway congestion can be presumed to have drawbacks, however, in terms of induced travel and possibly greater travel costs ...

Abstract: The automation of urban freeways is intended to reduce travel time costs, reduce direct (distance) costs, improve the safety of travel, create smoother vehicle operation, increase freeway lane capacity, and improve the ...

Abstract: A recent project simulating automated freeways in the Sacramento, Calif., region is described. Of special interest is the economic welfare model applied in this project. It was found that travel and emissions increase with ...

Abstract: It is unlikely that roadway construction or vehicle automation will be able to alleviate most major urban congestion in the near future (5–15 years). What else can be done to reasonably reduce congestion? Several approaches ...

Abstract: Population growth, continuing suburbanization, and higher labor‐force‐participation rates, combined with a virtual halt in new freeway construction, have led to rapid increases in traffic congestion in the U.S. This ...
