Dr. Lomax has been extensively involved in urban mobility research for more than 20 years. He developed and applied a methodology to assess areawide traffic congestion levels and congestion costs. The current study includes information on 85 cities throughout the U.S. from 1982 through 2003. The study examines trends in urban area mobility and documents the effect of transportation investments. Several measures of effectiveness have been used to describe mobility to a wide range of audiences including transportation professionals, public policy decision-makers, the media and the general public. The research, with funding from state DOTs and metropolitan planning organizations, will improve the mobility measuring capabilities and expand the ability to communicate with general audiences.He has been invited to make presentations on congestion, mobility and performance measure issues to a variety of groups including the Transportation Research Board, the Institute of Transportation Engineers and state and local governments in the U.S. He has testified before subcommittees of the U.S. House of Representatives, U.S. Senate and Texas Senate on mobility issues. He has appeared on PBS's "Lehrer NewsHour," National Public Radio's "All Things Considered," major television network news shows and many newspapers, radio and television stations in major cities covered in the annual mobility report.Dr. Lomax has also been involved in developing and evaluating a wide range of solutions to mobility problems, including high-occupancy vehicle facilities, and in improving decision-making processes and performance measurement. These studies assessed the need and cost effectiveness of potential improvements, improved the evaluation and prioritization processes and resulted in cost effective implementation of projects and programs.
