What design principle shift does the Puffin crossing represent compared to older, fixed-time systems?
Answer
Moving from a purely demand-based system to a responsive one
The reliance on sensors marks a significant departure from older designs, shifting traffic control from a purely demand-based system (press button, wait fixed time) to a responsive one based on real-time occupancy.
