Experience from 17 years of public transport priority in Poznań, Poland

Every city has a specific character, character of traffic included, therefore available public transport priority schemes should not be adapted directly in new locations, but should take into account local conditions. On the other hand, locally prepared applications might face significant problems. A presented in this paper example of a public transport priority evolution in Poznań, Poland might give some insight into problems with defining priority levels, local administration, detection and algorithms. Experience gained through 17 years of observing the priority development in Poznań shows further possibilities of improvement such as differentiating priority according to direction or time. A strong improvement of priority quality can be done by aggregation of information from local controls, allowing for incident warnings and reductions of detection cost.
