Answered By:

In the ongoing work to improve traffic signal operation at Stirling Corner, SCOOT control was introduced to the system in early September. SCOOT is an automated system whereby traffic queues are monitored and signal timings adjusted in real time to balance the flows on the various arms and avoid excessive queues developing.

During the bedding-in period after the introduction of this new system an issue was identified whereby the A1 northbound flow was not being allocated appropriate green time. I understand adjustments were made on the evening of the 25 September and the situation has improved.
