Short Biography

Dr. Lomax has been extensively involved in urban mobility research for more than 30 years. He developed and applied a methodology to assess areawide traffic congestion levels and congestion costs. The Urban Mobility Report examines trends in urban area mobility in 101 cities throughout the U.S. A related pooled-fund research project has developed several performance measures and analytical techniques to describe mobility to a wide range of audiences including transportation professionals, public policy decision-makers, the media and the general public.

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. He also played a role in the regional and statewide congestion analyses and in developing principles and performance measures to evaluate and communicate solution strategies. These studies included assisting the public agencies and business community in Atlanta and Houston to develop a process to estimate congestion levels, identify cost-effectiveness analysis procedures and the effect of a range of mobility improvement strategies. He was the lead researcher in a project to examine the benefits of transportation improvements and the cost of addressing congestion in major Texas metropolitan regions for the Texas Governor's Business Council , the Texas 2030 Committee and a joint working group of Texas DOT and Metropolitan Planning Organizations.

He has been invited to make presentations on congestion, mobility and performance measure issues to a variety of professional, civic, business and government groups. He has testified before subcommittees of the U.S. and Texas House of Representatives and Senate on mobility issues. He has appeared on radio and television network news shows and many newspapers, radio and television stations in major cities covered in the mobility report.
