Real Time Information

Urban ITS, Nottingham University, 23/11/2006

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 ITS, Nottingham University, 23/11/2006

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 ITS, Nottingham University, 23/11/2006

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

Urban Traffic Management and Control (UTMC)Case Study: Suffolk County Council UTMC

Urban ITS, Nottingham University, 23/11/2006

Suffolk County Council UTMC

Two lifting bridges Only way north and south of the river

UTMC implemented as part of a major regeneration scheme (Waveney Sunrise scheme): Including a new relief road

Background: Lowestoft

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

Not just Lowestoft: Bury St Edmonds

ITS Toolkit

Urban ITS, Nottingham University, 23/11/2006

ITS Toolkit

A website:

www.itstoolkit.co.uk

Officially titled “Understanding the Benefits and Costs of Intelligent Transport Systems”

Provides information and guidance for Local Authorities (and Students)
