Real Time Information
What is Bus Real Time Information?
How does it work?
Where it is used?
Urban ITS, Nottingham University, 23/11/2006
Real Time Information provides:
Detailed fleet information for bus operators
Urban ITS, Nottingham University, 23/11/2006
Real Time Information provides:
Information at bus stops: when the next bus is due other service information
Urban ITS, Nottingham University, 23/11/2006
Real Time Information provides:
SMS text messaging facilities;
Travel information booths
Web based information via a graphical interface.

How does Real Time Information work? (2)
Vehicles are fitted with Automatic Vehicle Location equipment, enabling their position to be tracked continuously using the Global Positioning System (GPS)
Bus position is transmitted to the central control station using wireless communications:
Private Mobile Radio; GPRS; MESH
Urban ITS, Nottingham University, 23/11/2006
How does Real Time Information work? (3)
A central computer uses this information to predict how long it will take for vehicles to reach stops
Arrival times transmitted to stops using wireless communications
This information is also can be relayed to a computer server for display on the internet
Urban ITS, Nottingham University, 23/11/2006
Public Transport Priority
In some systems, vehicles ‘request priority’ at traffic signals when behind schedule
A request is sent when the vehicle crosses a GPS cordon on approach to traffic signals
This request can either be relayed via an urban traffic control system or direct to the traffic signals themselves
Urban ITS, Nottingham University, 23/11/2006
Where is Real Time Information in use: Bristol
Four bus routes fitted with RTI
Installed Spring 2003
Information available at stops and online:
(www.acislive.com)
“Showcase” scheme also includes bus priority and road improvements
10% increase in bus patronage
Urban ITS, Nottingham University, 23/11/2006
Where is Real Time Information in use: Leicester
Star Trak system launched in 2000: Covers 34 routes, expanded into
Nottinghamshire and Derbyshire
Cost approximately £4 million
Routes equipped with Star Trak experienced a 28% patronage increase
Urban ITS, Nottingham University, 23/11/2006
Why invest in Real Time Information?
Many bus companies see major benefits from being able to locate their vehicles and manage their fleet better;
The public like bus real time information, it improves people’s perceptions of public transport;
When included as part of ‘whole route treatment’ RTI can increase bus patronage and reduce reliance on the car;
RTI systems provide a platform for other location based services e.g. provision of bus priority at traffic signals;
The public will pay for SMS services.

Real Time Information: The future
Road User Charging: Providing investment Integration into the charging system to present current
charging
Smartcards Electronic payment either on bus or at stop
Urban Traffic Management and Control (UTMC)Background

Urban Traffic Management and Control
Background
The system
Our Suffolk County Council project
Urban ITS, Nottingham University, 23/11/2006
Urban Traffic Management and Control (UTMC)
In the beginning: Individual traffic signals using fixed time plans
Problems: Needs to be updated to reflect changing traffic conditions Doesn’t cope well with differing traffic conditions, e.g. at
weekends in town centres or near sports stadiums before and after games, bank holidays, after road traffic collisions, etc.
Background (1)

Urban Traffic Management and Control (UTMC)
Next came computer controlled systems using induction loops in the road to detect traffic.
Two main examples in the United Kingdom are: MOVA (Microprocessor Optimised Vehicle Actuation )
Single junction
SCOOT (Split Cycle and Offset Optimisation Technique) Series of junctions
Background (2)
Urban ITS, Nottingham University, 23/11/2006
Urban Traffic Management and Control (UTMC)
Next development was to attach a database to the Urban Traffic Control system
This allowed traffic flows and speeds to be monitored
Problem was what to do with this information… Database was often isolated Different systems could not talk to each other
Background (3)
Urban ITS, Nottingham University, 23/11/2006
Urban Traffic Management and Control (UTMC)
System has a Common Database at its heart
Links all subsystems together
Common methods to exchange information
Allows information exchange between systems
Reduces costs as standard protocols used by all manufacturers
The solution

New Shopping Centre will mean less car parking spaces
To combat this a parking guidance system is being installed
Aim is to have the system operational in early December for Christmas shopping
