Elite Transportation Group, Inc. (ETG) was co-founded by Lawrence Liao and Lin Zhang in 2018. We specialize in travel demand modeling, big data analytics, traffic operations, traffic analysis and modeling, and intelligent transportation systems (ITS). Our co-founders have over 30 years of combined experience in the areas of travel demand modeling, traffic forecasting, transportation planning, traffic operations, corridor studies, toll operations, managed lanes, congestion pricing, traffic simulation and modeling, traffic signal systems, traffic impact studies, traffic safety, ITS, statistical data analysis, performance measurement, and benefit/cost analysis.
Mr. Liao has more than 20 years of experience in the areas of travel demand forecasting, transportation planning and big data analytics. He has developed and updated travel demand models at various levels – from cities and counties to metropolitan planning organizations (MPOs) and states, and for both trip-based and activity-based models. Mr. Liao has also applied travel demand models to support various projects, such as traffic impact studies, general plan updates, environmental impact reports, corridor studies, transit-oriented development, corridor system management plans, managed lane modeling, as well as federal research projects.
Mr. Liao is experienced in all major travel demand modeling software packages, including Cube, TransCAD, EMME, VISUM, Tranplan, and MINUTP, as well as, common programming languages, such as, Python, Java, MS Office VBA, C++, Pascal, and Fortran.
Mr. Liao is one of only five certified Cube Trainers in the world and is an expert in Cube-Voyager/TP+ scripting.
Dr. Zhang has more than 17 years of professional experience in the areas of transportation engineering and planning, with increasing responsibility in both the public and private sectors. Dr. Zhang has considerable experience in project management, traffic operations, corridor studies, traffic simulation and modeling, toll operations, managed lanes, congestion pricing, traffic signal systems, traffic safety, Intelligent Transportation Systems (ITS), statistical data analysis, performance measurement, and benefit/cost analysis. Dr. Zhang is a registered Professional Engineer (PE), Traffic Engineer (TE), and Professional Traffic Operations Engineer (PTOE). He is a Member of the National Academies’ Transportation Research Board (TRB) Committee on Freeway Operations, one of the most active and prestigious committees within the TRB.
