Clyde Lee receives Pioneer Award from Transportation Research Board

The Transportation Research Board Joint Subcommittee on Traffic Simulation “Traffic Simulation Pioneer Award” was presented Tuesday, January 19, 2010, by committee chair Dr. Tom Rioux to Dr. Clyde Lee, Professor Emeritus of The University of Texas at Austin, for his pioneering efforts in traffic simulation starting with the TEXAS Model for Intersection Traffic in 1968. The award was presented at the Center for Transportation Research in Austin, Texas.

Dr. Clyde E. Lee began his faculty career at The University of Texas at Austin on February 9, 1959, as an Assistant Professor. He advanced to Associate Professor in August, 1963, was appointed Professor in September, 1967, and retired February 15, 1999.

Dr. Lee was the founder of the Center for Highway Research (CHR) in 1963 and served as the center’s Director until 1980, when it became the Center for Transportation Research (CTR).

Dr. Lee’s research activities include pioneering work in the development and application of highway Weigh-in-Motion systems (he was awarded United States Patent No. 32665584 on August 16, 1966, entitled “Vehicle Weighing Scale with Overlapped Load Bearing Plates”), simulation of traffic control and vehicular flow at intersections, automated traffic data collection and analysis, and traffic monitoring for pavement and bridge research.

Dr. Clyde E. Lee was the faculty member who, in the late 1960s, conceived the idea of applying The University of Texas at Austin’s new Control Data Corporation 1604 mainframe digital computer for simulating traffic flow through an intersection. He initiated the first development efforts and supervised several ensuing research projects that culminated in the Traffic Experimental Analytical Simulation (TEXAS) Model for Intersection Traffic during the next couple of decades (initial development started in 1968 and the original release was in 1977).

He wanted accurate geometry including paths through the intersection; every driver-vehicle unit to be separately modeled in as much detail as possible; every form of traffic control including no control, sign control, and signal control; realistic lane changing; and a multitude of statistics that were appropriate for a traffic engineer to make informed decisions.

In 1965, Dr. Lee was the principal investigator for CHR Research Project 3-18-64-78 “Evaluation of Traffic Control at Highway Intersections” which developed special digital traffic delay recording equipment. The study was completed in March, 1970.
