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?
What is this project about?Real-Time Traffic Information System
Bus timetable and schedule management system
For Sydney (STA)◦Dynamic ◦Real-time◦Customer focused
IntroductionHand drawing timetable
Timetable at each stop
Electronic board
On-time Bus Service
BackgroundScenario ◦When will the bus arrive?
◦Did I just miss the bus?
◦Where should I get off?
◦How long does it take to the destination?
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Reason behind the problems:◦ Fixed timetable◦ Poor information provided◦ Information not correct/out of date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
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
Motivations Customer perspective:
Productivity & efficiency Convenience
Operator perspective: More customers More profits
Others: Environment issues Increasing population Worse traffic condition
Aims of this projectHigh-level ◦Accurate & reliable timetable◦Real-time information◦Speed up journey ◦Notify schedule changes
To make a bus system similar to train systems
Current solutionsReal-Time Passenger Information System
STA currently offers:◦SMS service which communicates with
Public Transport Information and Priority System Sydney Coordinated Adaptive Traffic System
Limitations of STA solution STA does not offer Importance
Access to real-time information Critical
Notification when the schedule changes Critical
Predicted arrival time on customers’ destinations Medium
Available seats information about the selected service Low
Effective bus priority Low
High quality on-time arrival Critical
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

Components of the system
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%.
Expected outcomes Current system RTTIS
On-time performance 95.9% 98.9%
On-time arrival 60% 95%
Average delays 2-5 minutes 1 minutes
Customer satisfaction Medium High
Bus bunch High Low
Challenges Uncertainties, unpredictable ◦ Traffic jam◦ Incident ◦ etc.
Hard to achieve “real-time”
New technology to improve performance◦ 90 seconds to apply traffic light changes
Future workE-ticket
Wireless on bus
Weather information system
Integrate with other transport systems
