  1. Bus timetabling and scheduling ITEC 810 Project Supervisor: Stephen Smith Xinru Ma (42622611)

  2. Agenda • What is this topic about? • What are the current problems? • What are the current solutions and limitations? • How do we solve the problems? • What are the expected outcomes? • What are the future directions?

  3. What is this project about? • Real-Time Traffic Information System • Bus timetable and schedule management system • For Sydney (STA) • Dynamic • Real-time • Customer focused

  4. Introduction • Hand drawing timetable • Timetable at each stop • Electronic board • On-time Bus Service

  5. Background • Scenario • When will the bus arrive? • Did I just miss the bus? • Where should I get off? • How long does it take to the destination?

  6. Problem statement • Current problems: • Delays • Left early • Customers are upset • Reason behind the problems: • Fixed timetable • Poor information provided • Information not correct/out of date • Customers want: • Accurate bus arrival time • Bus stop information • Estimated arrival time

  7. What customers want? • Research shows customer want to know • Actual bus arrival time (80%) • On-time performance (70%) • Delay time (60%) • My opinion: • Exact arrival time > on-time performance rate • More information  choices  confidence • Notification  reliable  commitment  more travellers

  8. Motivations • Customer perspective: • Productivity & efficiency • Convenience • Operator perspective: • More customers • More profits • Others: • Environment issues • Increasing population • Worse traffic condition

  9. Aims of this project • High-level • Accurate & reliable timetable • Real-time information • Speed up journey • Notify schedule changes • To make a bus system similar to train systems

  10. Current solutions • Real-Time Passenger Information System • STA currently offers: • SMS service which communicates with • Public Transport Information and Priority System • Sydney Coordinated Adaptive Traffic System

  11. Limitations of STA solution

  12. Improvements • Automatic Vehicle Location system • Mobile Digital Computer (MDC) • Drivers involvement • Historical data to improve timetable • Bus priority system • On street surveillance camera • Improved response time • Traffic management system • Data Management system and GIS • Traveller Information system • Computer Aided Dispatch and Scheduling

  13. The proposed RTTIS

  14. Components of the system

  15. Improve system performance • The on-time performance can increase by 20% with the aid of the Automatic Vehicle Location system and Computer Aided Dispatch and Scheduling. • The travel time can be improved by 10% by implementing the Bus Priority system. • Improve the emergency response time by 50%.

  16. Expected outcomes

  17. Challenges • Uncertainties, unpredictable • Traffic jam • Incident • etc. • Hard to achieve “real-time” • New technology to improve performance • 90 seconds to apply traffic light changes

  18. Future work • E-ticket • Wireless on bus • Weather information system • Integrate with other transport systems

  19. End of presentation Thank you
