Urie Bezuidenhout presented on changing driver behaviors through user interaction to reduce traffic congestion. Some key points: 1) Congestion costs Auckland over $1 billion per year. Short term solutions include influencing driver behavior now and optimizing traffic signals on a cycle-by-cycle basis to minimize queues. 2) An experiment in Auckland CBD optimized traffic signal offsets using queue data which reduced travel times by 5% in the short term and 20% in the medium term. 3) Gradually changing driver behaviors over 4-6 weeks, such as using queues to discourage turns and flushing out queues before drivers arrive, can further reduce congestion in a sustainable way.
