MOST is a new approach to learning about traffic signal timing. MOST uses a new simulation environment to let you directly observe how the signal timing parameters that you select affect the quality of traffic operations at a signalized intersection.
The MOST course includes seven separate laboratories, with nearly forty individual experiments. Each experiment has one or more specific learning objectives that will guide your work during that experiment. Five of the laboratories cover isolated actuated intersection operations, while two cover coordinated signal systems.
The MOST course is not about learning how to use a specific simulation model, though the experiments that you will complete are conducted using the VISSIM microsimulation model. Nor is it about a specific traffic signal controller, even though you will use Econoliteís ASC/3 controller emulator. Finally we will not present you with guidelines or standards that you should follow. The newly-released Traffic Signal Timing Manual produced by the Federal Highway Administration will provide you with this type of information.Rather, you will use the MOST simulation environment to directly see the results of the phasing plan and timing parameters that you select. Using VISSIMís animation and movie files, you will visualize the duration of a green interval, the length of a queue, or the delay experienced by vehicles traveling through a signalized intersection with the phasing and timing plan that you design. And you will use this information to make judgments about the quality of intersection performance, and whether you need to make further adjustments to the signal timing to improve intersection operations. It is almost as good as standing out at an intersection, with one eye on the traffic and the other on what is happening in the controller cabinet.
Unlike many courses that emphasize an instructor-focus (with lectures presented to students), the MOST course emphasizes a student focus in which you will learn by doing the experiment, analyzing data that you collect, and drawing conclusions about what makes good signal timing practice.
All of the materials that you will need to complete the MOST course are included on this web site.
If you are an instructor, additional materials are available on the Instructor Materials link.
