Handling efficiently and effectively real-time vehicle control is a major concern of public transport (PT) operators. One related problem is how to reduce the uncertainty of simultaneous arrivals of two or more vehicles at a transfer point. Improper or lack of certain control actions lead to missed transfers, one of the undesirable features of the PT service. Missed transfers result in increases in passenger waiting and travel times, and passenger frustration.

This work focuses on reducing the uncertainty of missed transfers by the use of control tactics in real-time operation. The developed model improves the PT service performance by optimally increasing the number of direct transfers and reducing the total passenger travel time.

The implementation of the concept is performed in two steps: optimization and simulation. The optimization searches for the best combination of operational tactics. The simulation serves as a validation of the optimal results under a stochastic framework.

A case in Auckland, New Zealand is used.
