Description

This T3 webinar introduces Mobile Signal Timing (MOST) training, an exciting new approach to learning traffic signal timing. MOST uses a simulated traffic signal environment to provide traffic engineers with immediate visual feedback on how changes to signal timing parameters affect the quality of traffic operations at a signalized intersection. This T3 webinar will provide an overview of the tools and concepts used in the MOST training, and will include demonstrations of the laboratories and the simulation software as it responds to real-world signal timing scenarios. The MOST training is currently being developed and is geared toward practicing traffic engineers in state or local transportation agencies, as well as toward new engineers embarking on their career. This webinar is an overview of the simulations and tools used in MOST training. Itís intended to highlight the unique delivery of MOST training. It is not the full MOST training course.

The approach used in the MOST course is based on seven laboratories and nearly forty separate experiments in which students are (1) presented with a clear learning objective, (2) given one or more tasks that involve intensive observation of and/or data collection at a signalized intersection, and (3) taken through a thoughtful and guided analysis and interpretation of the results of the observation and data collection within the framework of the learning objective. The students learn by observation, by doing, and by reflection on what they observed and did. This active learning process is more difficult than simply listening to a lecture or slide presentation but it nearly always guarantees a deeper learning and understanding of the subject matter than those that result from more passive learning environments.

The MOST training course, currently being developed, will expand significantly on the concepts presented in the webinar. You can learn more about the MOST course at the following web site: http://www.webs1.uidaho.edu/most/.

More about MOST Training

The MOST training course includes seven separate laboratories, with nearly forty individual experiments. Each experiment has one or more learning objectives that guide the student's work during that experiment. Five of the laboratories cover isolated actuated intersection operations, while two cover coordinated signal systems.

Students use the MOST simulation environment to directly see the results of their phasing plan and timing parameters that they set. Using VISSIM's animation and movie files, combined with the phasing and timing plans, students visually experience the duration of a green interval, the length of a queue, or the delay experienced by vehicles traveling through a signalized intersection. Students use this information to make judgments about the quality of intersection performance, and whether further adjustments to the signal timing are needed to improve intersection operations. Students will find that MOST training is nearly as good as standing out at an intersection, with one eye on the traffic and the other on the controller cabinet.

It should be noted that the MOST course is not about learning to use a specific simulation model or a specific traffic signal controller, even though experiments are conducted using the VISSIM microsimulation model and Econolite's ASC/3 controller emulator, respectively. Furthermore, the training does not recommend guidelines or standards (the newly-released Traffic Signal Timing Manual produced by the Federal Highway Administration will provide you with this type of information). The focus of MOST training is on experimenting with simulated environments, analyzing data, drawing conclusions about what makes good signal timing practice, and implementing those practices in the field.
