Dr. Joe Wilkinson - - Chaparral's founder is Dr. Joseph E. Wilkinson. Prior to founding Chaparral in 1987, Dr. Wilkinson spent 25 years programming and performing statistical analyses on a vast array of computers, working in both the public and private sectors. His experience includes programming, training, data analysis, reporting, andJoe Wilkinson computer hardware design and construction. He received his doctorate in experimental psychology from Baylor University.
In 1988, Chaparral won a contract to develop the State of New Mexico's traffic monitoring system. That market has since expanded so that the company now specializes in traffic software products and research services. One of Chaparral's primary products is TRADAS (Traffic Data System), a system for collecting, editing, summarizing, and reporting a wide range of traffic data. A second version of this product (TRADAS 2) was released in the spring of 1998. In TRADAS 2, the underlying software platform was changed from SAS to C++, an object-oriented programming language. TRADAS 2 also added Oracle™ as the repository of traffic data and statistics. Dr. Wilkinson is also involved in developing traffic data collection standards. He was a member of the American Association of State Highway and Transportation Officials (AASHTO) task force, which produced the AASHTO Guidelines for Traffic Data Programs in 1992. In addition, he is a member of the team headed by Cambridge Systematics that is revising the Guidelines. He has served as a member of ASTM since 1992, and is currently preparing the ASTM standard for archiving traffic data from intelligent transportation systems. He was a member of the team for NCHRP 1-39, which established the traffic data requirements for the Mechanistic-Empirical Pavement Design Guide software. He personally wrote the original user interface for the resulting TrafLoad software. His earlier experience in experimental design, instrumentation, and statistical analysis has enabled Dr. Wilkinson to function in a variety of traffic-related research activities. He was a consultant to the Strategic Highway Research Program's (SHRP's) Expert Task Group for Traffic Monitoring and has carried out several traffic research analyses in conjunction with Cindy Cornell Martinez (see Cindy’s staff details below).

After joining Chaparral, she was lead statistician on the Strategic Highway Research Program's (SHRP) LTPP project, where she performed numerous analyses of the WIM and vehicle classification data from the SHRP sites. She analyzed vehicle length as a predictor of axle-based vehicle classification as background research for the latest Traffic Monitoring Guide. Most recently, at the 2006 North American Travel Monitoring and Exposition (NATMEC), she presented a paper describing a procedure for establishing length categories for optimal length classification. Ms. Cornell Martinez has written and co-authored numerous papers, including Computational Procedures for LTPP Traffic Data Annual Summaries in the Researcher's Guide to the Long-Term Pavement Performance Traffic Data (June 1996), LTPP Traffic Monitoring Equipment Survey and Result (1996), Empirical Analysis of Alternative Data Collection Sampling Plans for Estimating Annual Vehicle Loads at LTPP Test Sites (1995), and Use of Vehicle Length Data for Classification Purposes: The Research and a Suggested Procedure (NATMEC, 2006).
