The project's primary objective is to document the microscopic characteristics of protected and permitted left-turn operational parameters at signalized intersections using the NGSIM datasets. The microscopic characteristics of the following parameters are investigated and documented as part of the project: vehicle turning path, start-up lost time, saturation flow rate, and speed and time headway profiles along the turning path. While the sample size for some of the cases might not be large enough to allow for full statistical analysis, the data presented in this report provides insights on different elements of driver behavior as it relates to left-turn operations., 1333

University of Idaho, Kyte, Michael, Tribelhorn, Maria, National Institute for Advanced Transportation Technology (U.S.), United States. Dept. of Transportation. Research and Innovative Technology Administration, US Transportation Collection, This report presents materials that can be used as the basis for a module on signalized intersections in the introductory, course in transportation engineering. The materials were developed based on studies of the work of students who took, this introductory course, including analysis of examination results, homework assignments, and interviews with students, to identify concepts that were particularly difficult for them. Existing textbooks commonly used in the introductory course, were reviewed to identify how concepts and topics related to signalized intersections were treated. Standard guidebooks, used by transportation professionals were reviewed to identify concepts that would be appropriate to include in a new, curriculum. The following guidelines were used to develop these materials, • Understanding the basic operation of a traffic controller is an important foundation for a realistic understanding of, how a signalized intersection works., • Focusing on the automobile user and pretimed operation allows the student to learn about fundamental principles of, a signalized intersection., • Queuing models are presented as a way of learning about the fundamentals of traffic flow at a signalized intersection., • Only those equations that students can apply with some degree of understanding are presented., • Learning objectives are clearly stated at the beginning of each section so that the student knows what is to come., • Graphically illustrating basic concepts is an important way for students to learn.

Dept. of Transportation. Research and Innovative Technology Administration, University Transportation Centers Program (U.S.), US Transportation Collection, The potential failure modes of a network based accessible pedestrian system were analyzed to determine the limitations and benefits of closed-loop operation. The vulnerabilities of the system are accessed using the industry standard process know as Failure Modes and Effects Analysis. This analysis reveals that because the closed-looped operation increases operational observability, there is only one failure mode that is not detectible. Investigation on reliability of hardware and software indicate that the probability of this particular event is extremely low. The three primary components of a distributed realtime control system are hardware, software, and communications. Environmental conditions are the predominant factors that determine hardware reliability. The system was tested for its ability to function in the presence of electrical transients specified by the National Electrical Manufacturers Association (NEMA). All hardware components meet or exceed NEMA temperature requirements. Software errors are difficult to detect and difficult to predict. Best practices in development and testing can minimize the number of errors. Testing includes multiple years of both laboratory and field testing.

This report describes a project that developed curriculum and visualization tools to train transportation engineering students to more deeply understand complex traffic control systems and to have an increased ability to prepare designs to improve these systems. Prototype tools and curriculum developed as part of this project addresses several traffic signal operations modes including actuated control, coordination, and railroad preemption.

School of Civil and Construction Engineering, United States. Dept. of Transportation. Research and Innovative Technology Administration, US Transportation Collection, National agencies have called for more widespread adoption of best practices in engineering education. To facilitate this sharing of practices we will develop a web-based system that will be used by transportation engineering educators to share curricular materials and methods. A research-based action oriented approach will be taken where we iterate between development and studies of usability and adoptability of the system. The efforts described in this report are the first in two stages and include the development and testing of a pilot system, including research efforts that support the development, and the gathering of existing curricular materials to be uploaded to the system. Diffusion of Innovations (DI) Theory has been used extensively to study and implement the characteristics of a system that will facilitate its broad use by educators. This research and development effort will rely on DI theory, with a specific focus on characteristics of an innovation known to affect adoption. Understanding potential adopters’ experiences, opinions, and values enabled the initial development of the web-based repository’s architecture. Interviews with these individuals and a supplementary analysis of syllabi in relevant courses afforded the initial development of the web-based repository according to the tenets afforded by DI theory. The results of this study suggest tangible and direct means of addressing potential users’ perceptions about the repository and the materials included within it, such as managing the size of materials provided onsite and providing various ways of accessing the materials. Next steps in this project include one more sequence of usability and adoptability studies followed by the development and dissemination of PTERC to a broader audience.

Federal Highway Administration, Kyte, Michael, Beyerlein, Steve, Brown, Shane, Monsere, Chris, Goodchild, Anne, Pitera, Kelly, Lee, Ming, National Institute for Advanced Transportation Technology (U.S.), NTL-PLANNING AND POLICY-Education, Federal Highway Administration, This project developed four new activity-based transportation courses including “Traffic Signal Systems Operations and Design”, “Understanding and Communicating Transportation Data”, “Introduction to Freight Transportation”, and “Rural Highway Design and Safety”. The courses are learner-centered in which activities completed by students form the basis for their learning. The courses were offered fourteen times to a total of 195 students. Activity books that included 142 activities were developed for the four courses. The books and all supporting materials are available on the project web site. A number of assessments and evaluations were conducted to determine how effective the courses and materials were in meeting project objectives. The active learning style was a challenge for many students, as they were required to be prepared for class and to do “active” work during class. In general, there was an acceptance of the value of the active learning environments and how they positively contributed to student learning.

Federal Highway Administration, Idaho, Variable message signs, Speed, Weather conditions, Sensors, Visibility, Drivers, Behavior, Traffic crashes, Storms, Warning systems, Operations, Tests, Information dissemination, Idaho, NIATT Report No. N00-04, The Storm Warning Project was initiated in 1993 as a result of a large number of serious traffic crashes that occurred during periods of low visibility on I-84 in southeastern Idaho between 1988 and 1993. The purpose of the project was to determine if visibility sensors and the resultant information supplied to drivers on roadway message signs would reduce vehicle speeds to safe levels as warranted by weather conditions. The report is organized to provide information in a sequence that corresponds to the chronology of the project. Section 1 introduces the project, and provides an overview of its history, a description of the systems tested, test objectives, and evaluation approach. Section 2 reports on the performance and reliability of the sensors. It documents Phase I of the project, which involved evaluating the sensors' ability to determine low visibility conditions. Section 3 discusses the response of drivers to the driving conditions and to the information provided by variable message signs. It documents Phase II of the project, which studied the degree to which driver behavior could be modified through presentation of roadway condition information via variable message signs. Section 4 presents the results and conclusions of this operational test., 954
