Improving Bus-Passenger Transfers on Road Segments through On-Line Operational Tactics

The use of transfers in public transit has the advantages of reducing operational costs and introducing more flexible, efficient route planning. In contrast, the main drawback from the passengers’ point of view is the inconvenience of traveling multi-legged trips. In order to diminish the waiting time caused by passenger transfers, synchronized timetables were introduced. The use of these timed transfers suffers from uncertainty about the simultaneous arrival of two (or more) buses at an existing stop, which can lead to deterioration in system reliability. In order to alleviate the uncertainty of simultaneous arrivals, a new passenger-transfer concept was developed that extends the commonly used single-point encounter (at a single transit stop) to a road-segment encounter (with any point along the road segment constituting a possible encounter point). The objectives of this work are three-fold: (a) to define the bus-encounter probability along a road-segment, (b) to introduce a simulation model to estimate the bus-encounter probability, and (c) to model the bus-encounter probability upper bound. It is believed that the proposed concept will reduce the uncertainty of meeting at a point and enable more flexibility in deploying on-line operational tactics (hold, skip stop, short-turn, etc.).
