Overview on Floating Vehicle Data (FVD) technology
FVD units ITIS developed the concept of the Floating Vehicle Data Unit based on vehicle mileage travelled and driving patterns, whereby: In addition to the above fleets ITIS signed data supply contracts with large telematics companies that track vehicles for logistics and fleet management purposes. ITIS also targets probe vehicles that may be required to increase data quality in a more localised urban or inter-urban area, such as a local haulage or taxi operators.
How did ITIS build an FVD network? Fleet company #3 1.1bn records 4m per day Fleet company #2 AA Patrol Working with others has built scale and made a high quality network economically feasible Fleet company #1
Details on Cellular Floating Vehicle Data (CFVD) technology
Founded July 2000 Management A group of specialists that have conceived and developed highly sophisticated war-games, command and control and intelligence systems for the Israel Defence Forces Primary application Low cost, patented technology for measuring and forecasting traffic flow Acquired by ITIS Holdings December 2003. Cellular Floating Vehicle Data:created by Estimotion inc.
How does it work? • Cellular handover data required at • A-link interface: • Handover request • Handover required • Handover request ACK • Handover command • Handover complete • Handover succeeded • Handover failure • Assignment request • Assignment completed • Assignment failure • Paging • Setup indication • Cellular handover data required at • MAP interface: • MAP prepare handover • MAP prepare subsequent handover • MAP send handover report • MAP allocate handover number Direction of travel Cell Cell Cell Overlaid on Navigation quality GIS Flow pattern Analysed against GPS drive data And adjustments made to pattern model Iterative process Creates sample observer to observe flow patterns
Location Module Testing Data obtained from Thems testing is compared to data derived from the handover location module Handover event GPS data Location area derived from location module
Path Finding Tests Cellular Phones are tracked in a given vehicle fitted with a GPS unit to determine overall accuracy of the map-matching algorithms The results of these test drives has shown that the path finding algorithms are extremely accurate with an accuracyof between 95 to 97% on interstate roads and at least 85% on urban roads.
Static Speed Tests Velocity from Cellular system compared to data obtained from static loop system
Dynamic Drive Tests A known vehicle completes a journey covering both urban and inter-urban roads and the measured journey time is compared to the predicted journey time

Travel time, not velocity. The technology is based on extracting travel time information and not velocities from the supplied data. This has the advantage of providing extremely accurate journey time information. Merging of historic and real-time data. The system does not consider traffic information to be static but combines both historic and real-time traffic information to generate accurate predictions of traffic congestion. Advanced GIS modelling. Advanced GIS techniques are used to model the topology of the road network taking account of the different turning options within a given network. This means the system can provide accurate traffic information in complex road networks such as dense urban areas. Data independent. The technology is not dependent on any single positioning technology and can be adapted to take almost any form of location information. The algorithms have been developed to cope with inaccurate locations and very noisy data to achieve the accuracy and comprehensive road coverage required to provide high quality traffic information. Data fusion. Data can be fused from different information sources including mobile and static sensors and journalistic data reports. Knowledge-based algorithms. A series of learning-based algorithms have been developed which constantly update the historic traffic patterns used within the system. Unique technology features
There are currently a number of projects being implemented using the ITIS CFVD technology: Antwerp, Holland – broadcast stage Baltimore, USA – broadcast stage Scotland - data presentation stage London – pattern matching stage Tel Aviv, Israel – 2 years since implementation Missouri DOT, USA – contract awarded for statewide data CFVD customers
The Baltimore CFVD Project • Covers 500 square miles • Live data (24/7) on over 350 miles or road • 140 miles of expressways and over 200 miles of arterials

TELCO WAP/SMS ITIS currently provide two WAP traffic services, for Vodafone Live! and Orange World. Vodafone customers are able to browse for the latest traffic information directly from their handsets as well as being able to request AA recommended routes complete with any relevant traffic delays. Orange customers are able to receive constantly updated traffic flow information displayed in colour, and can scroll up and down affected segments of any UK motorway to see a colour-coded scale that shows current traffic conditions.
A web based application offering a number of travel and traffic related services. ITIS currently supplies web based traffic and mobile based traffic services. Text TRAFFIC to shortcode 82085 GetMeThere.co.uk will send you a map, via WAP push, showing current traffic conditions in the area you are located for only £1!

The AA is the UK's largest motoring organisation with over 12 million members. In May 2002 ITIS and Automobile Association Developments Limited, part of the Automobile Association (the AA) announced a significant strategic relationship. Under the terms of the deal, ITIS became responsible for supplying real time traffic flow information to AA Roadwatch, the leading provider of traffic and travel news in the UK. This relationship was strengthened in October 2002 when ITIS also became responsible for operating the AA's short dial IVR traffic information service under the AA Roadwatch brand, as well as providing real time traffic flow information to the AA's website. At the same time, the AA agreed to provide ITIS with location data from its AA patrol vehicle fleet, providing a valuable source of data for the ITIS Floating Vehicle Data system (FVD®).
