  • Single cycle offset adjustment for traffic signal controllers using a threshold percentage of the cycle length
    Patent number: 9189957
    Abstract: Embodiments include a method for single cycle offset adjustment for a traffic signal includes receiving a current signal control plan and a new signal control plan. The method also includes calculating an offset between the current signal control plan and a new signal control plan and determining if the offset is less than a threshold percentage of a cycle length of the new signal control plan. If the offset is less than a threshold percentage of the cycle length, the method includes reducing a time period of each phase of a next cycle of the new signal control plan. If the offset is greater than the threshold percentage of the cycle length, the method includes increasing the time period of each phase of the next cycle of the new signal control plan. The method also includes executing the new signal control plan.
