Summary
This document serves as a compendium of papers produced during the eleventh offering of the Mentors Program on Advanced Surface Transportation Systems at Texas A&M University in 2001. Sponsored by the Southwest Region University Transportation Center and the U.S. Department of Transportation, the program facilitated collaboration between graduate students, state Department of Transportation employees, and six senior transportation experts. The compendium aggregates research on intelligent transportation systems (ITS), traffic operations, and management, with specific focus areas including portable traffic management systems, incident management, traveler information, and bus priority systems. The primary research contribution detailed in the provided text is a paper by Michael D. Fontaine titled "Guidelines for the Application of Portable Traffic Management Systems at Work Zones." This study addresses the safety and congestion risks associated with construction zones, particularly where lane closures create queues that high-speed vehicles may encounter with insufficient warning. The research objective was to develop objective guidelines for transportation agencies to determine the appropriateness, placement, and configuration of Portable Traffic Management Systems (PTMSs). PTMSs integrate portable changeable message signs, speed sensors, and highway advisory radio to provide automated, real-time traffic management. Fontaine’s methodology involved a comprehensive review of literature and telephone interviews with personnel involved in past PTMS evaluations. The study analyzed field operational tests conducted in Minnesota, Maryland, Iowa, Kentucky, Nebraska, Illinois, and Ohio to assess system performance. Based on this analysis, the paper establishes criteria for well-designed PTMSs, emphasizing credibility, clear messaging, sensor accuracy, reliable communications, ease of installation, and cost-effectiveness. The research produces specific guidelines for determining PTMS applicability based on congestion presence, work duration, and the utility of speed or travel time advisories. Additionally, it provides technical guidance for the physical placement of system components, such as changeable message signs and speed sensors, within work zones. These guidelines were validated through an application to an existing Texas work zone. The significance of this compendium lies in its synthesis of practical, field-tested strategies for implementing advanced transportation technologies. By providing structured guidelines for PTMS deployment, the research aids agencies in making evidence-based decisions regarding work zone safety and efficiency. The broader collection of papers in the compendium reflects the program’s goal of bridging academic research with state-level transportation needs, offering insights into topics such as freeway travel time estimation, automated vehicle location for equipment usage, and unified incident management plans. The document underscores the value of mentorship in advancing the application of ITS technologies to solve complex transportation problems.
