The new traffic signals on Ocean Drive use a TfNSW traffic-responsive system. Sensors in the road monitor traffic and adjust green times in real time.
Because the system responds to overall traffic patterns, it may not react instantly to a one-off surge (for example, a queue arriving all at once or a group of cyclists). It can take a couple of signal cycles to rebalance the intersection.
To improve traffic flow, TfNSW has increased the minimum green time on these approaches. Larger intersections also have a longer all-red period between phases so the intersection can clear safely before the next movement begins.
For safety, drivers and riders should not enter the intersection on amber if they can stop safely.
