This work presents an optimization procedure with real-time operational tactics to decrease or eliminate bus operational deviation from schedules, and to increase the actual occurrence of synchronized transfers at planned network transfer points. An arrival time deviation-based dynamic speed adjustment model is proposed for updating vehicle operating speed in real time. Three operational tactics, including changing speed, holding and skip stopping strategies are tested in the optimization using real-time information. A case study tests how close the vehicle’s running status keeps up with the planned schedule and how much delays change after deploying the tactics tested. Results show that by applying the proposed methodology, the length of deviation interval for direct transfer can be significantly increased on two routes tested by between 798% and 353%. Buses can arrive at transfer points as planned while departure time deviation ranges from -600s/+417s and from -600s/+839s for the two routes tested. Areas for future research are identified.
