This website has been created to train students and practicing engineers the basics of signal timing and controller programming. To that end there are four basic modules on this site. These modules cover Pretimed Signals, Actuated Signals, Coordinated Signals, and Hardware in the Loop Simulation (HILS). The first three modules attempt to teach the user the basics of that aspect of traffic signals. The HILS module is an informational module about the development of simulations utilizing actual traffic controllers and can be reviewed at the user's leisure.
The modules for pretimed, actuated, and coordinated signals consist of two parts, a Background and an Exploration section. The background section introduces the concepts related to the particular signal type and the exploration section has case study problems to help the user better understand the concepts presented in the background section. The case studies make use of HILS hardware and software, but can still be informative without access to that equipment.
The materials were designed for the user to read the background materials and then proceed to the case studies. The case studies start out with some given information and have a list of steps to lead the user through the process of determining a signal timing plan based on the background of that module. A couple of example steps are shown to the left.
The link "Controller Settings" will take the user to a page explaining what is to be done for that step. The indented text below the step contains specific instructions that supplement the linked page. These extra instructions are easy to overlook but are important to the correct completion of the step.
To further help the user, the Tools menu in the menu bar on the left side of the page has links to pages that are useful throughout the site.
You should have all of the information necessary to successfully utilize this site. Please continue on to Basic Signal Timing.
