The Benefits of Signal Group Oriented Control
Recorded Presentations from the meeting are now available. A folder icon represents that recordings are available for at least one presentation in the session.
Purchasing Recording Access: ITS America is now offering the option to purchase whole meeting or track access to the recordings if you were not a full registered attendee of the meeting. You may Purchase Full Meeting Access or you will have the option to purchase just individual track access. If you want to purchase multiple tracks, you will need to browse to a recording in each track to purchase that individual track. Full registered meeting attendees still have free access using their registration credentials. Please email email@example.com if you need your registration credentials sent to you.

Description of Paper:
Currently there are many different traffic light control algorithms. They can be roughlyclassified as fixed time, vehicle actuated or traffic responsive. All of these control algorithmshave stages, blocks or similar concepts at their basis that impede flexibility. This paper willtherefore present a signal group oriented algorithm that is not bound by any constraints. Thismeans that any combination of signal groups that is allowed by the conflict matrix can beshown in any order. To isolate the effects of shifting to signal group oriented control, thispaper will also test the same controller as a modified version that respects stages and stageorders. These tests revealed that the overall time lost for all vehicles can be reduced by up to 20% by switching to signal group oriented control.
