Accommodating non-stop public transport in urban traffic control

Priority at intersections is a good way to improve the quality of public transport. Priority ranges from avoiding delays, to giving green to public transport at the earliest possibility in the cycle. There is a trade-off between smooth handling of private traffic and public transport priority. Priority can be disruptive, with a big impact on overall performance and stops of private traffic - with the associated environmental impact. New computer guided vehicles, like the Phileas bus, challenge the trade-off. These new vehicles need absolute priority. New mechanisms were designed and implemented that give absolute priority with minimal disruption to other traffic. For the covering abstract see ITRD E134653.
