Tallinn University of Technology March 2013  MODES In its initial state, the system is functioning in Automatic mode. By turning switch 3 on the main controller, Manual mode will be enabled on both of the crossroads. At this point, each of the crosswalks can actually be toggled between Democratic mode and Main Street mode. AUTOMATIC MODE Automatic is the default mode. In this mode, the sensors are not active, and the lights switch automatically back and forth after fixed periods of time. In this release, the time periods are equal, but it is possible to give lower-priority roads a smaller time window. This mode is suited to be used in busy hours of the day.
