According to the Urban Mobility Report, congestion has caused 4.2 billion hours of travel delay and 2.9 billion gallons of wasted fuel to a total cost of $78 billion in 2007. Funding additional road construction to keep pace with traffic growth requires large capital costs and other social and environmental costs that many communities are increasingly unwilling to accept. Another solution is to greatly improve the efficiency of the existing surface transportation network through research and implementation of advanced traffic control, operation, and management technologies as well as reliable public transportation systems. Traffic Engineering discipline prides itself on providing these improvements and offering the mobility choices to reduce congestion and emissions. At Texas Tech University, Traffic Engineering is a branch of Civil and Environmental Engineering Department. The TransTech Laboratory was established as part of TechMRT in fall of 2004 when Dr. Hongchao Liu was brought to the university. Research interests of this lab encompass many aspects of urban and rural surface transportation systems, with particular focuses on: 1) advanced traffic signal control algorithms for large and congested street networks; 2) macro-, meso- and microscopic traffic simulation models; 3) traffic data analysis; 4) asymmetric full velocity car following models and application of advanced computation techniques in traffic flow study; and 5) application of GPS and GIS technologies in transportation and advanced map-matching algorithms for vehicle navigation.
