Offline Offset Refiner for Coordinated Actuated Signal Control Systems1
Publication: Journal of Transportation Engineering
Volume 133, Issue 7
Abstract
This paper presents the concept and implementation of an offline offset refiner, which addresses the problem of uncertain (not fixed) starts/ends of green in the determination of offsets for coordinated actuated signal control. Making use of a large amount of archived signal status data available from real-time signal operations, the refiner may fine tune the signal offsets to provide smoother progression in either one-way or two-way coordination. The proposed offset refiner is easy to implement and can work readily with current closed-loop signal control systems to improve their system performance.
