Coordinated Signal

This section describes the inputs to use for an 8-signal group fixed time coordinated signal operating with a 110-second cycle length. This example uses the minimum features necessary for this type of signal control and only those features are displayed in the timing figures below. Features of this example include:

  • Controller frequency of 1
  • 8 vehicle signal groups
  • 2 overlap signal groups
  • 4 pedestrian signal groups
  • Left-turns are all protected and leading
  • Dual entry is set for through movements
  • The local zero point in the cycle is defined as Lead Green which is the start of green of the first coordinated signal group
  • 35-second offset to master controller from the local zero point
  • Pedestrian signal groups have pushbuttons

Free Running Signal

This section describes the inputs to use for a T-shaped fully-actuated Free Running signal. This example uses the minimum features necessary for this type of signal control and only those features are displayed in the timing figures below. Features of this example include:

  • Controller frequency of 10
  • 4 vehicle signal groups, 1 overlap signal group
  • 2 pedestrian signal groups
  • Dual entry is set for signal groups 4 & 8
  • Protected left-turn (signal group 3) is leading
  • Vehicle Signal Groups 2, 3, 4, and 8 are all actuated and have detectors that call and extend the signal groups
  • All pedestrian signal groups have pushbuttons

Signal with Plan Change

This signal controller changes plans twice during the simulation. This example uses the minimum features necessary for this type of signal control and only those features are displayed in the timing figures below, opening the planchange.ini settings file within the RBC dialog will allow you to see the timing in the same format as in the figures. Features of this example include:

  • Controller frequency of 2
  • 8 vehicle signal groups
  • 2 pedestrian signal groups
  • Signal Groups 4 and 8 are set to maximum recall
  • Pedestrian signal groups 102 and 106 have pushbuttons
  • Vehicle Signal Groups 1, 2, 3, 5, 6, and 7 are all actuated and have detectors that call and extend the signal groups
  • Protected left turns north and south bound
  • Protected/Permitted Phasing: left turns east and west bound and right turns north and south bound
  • Starts in Free Running Mode
  • Two Patterns
  • Pattern 1 is coordinated and starts at simulation second 600
  • Pattern 2 is Free Running, uses Max Green 2 times, and starts at simulation second 1500
  • Left-turns are all leading for Base Timing and Pattern 1
  • Signal Groups 3 and 7 are lagging for Pattern 2
  • For Pattern 1, the local zero point in the cycle is defined as Lead Green which is the start of green of the first coordinated signal group
  • For Pattern 1, 35-second offset to master controller from the local zero point
