Casualty reduction
2010 target of 50% reduction in fatalities
Prime purpose of ITS, eSafety and related initiatives is to reduce casualties on the road
How can ITS functions improve casualty reduction?

Where are we now?
Pre-crash Road safety – driver training, road design, roads policing, vehicle performance and maintenance, belt use, helmets
Crash Crashworthiness - Restraints, structure design, biomechanics
Post-crash Rescue – Paramedics training, extrication, hospital provision
![Page 4: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/4.jpg)
VehiclesPrimary Safety
Conventional vehicle dynamics – braking, handling, cockpit ergonomics etc
Primary NCAP – significant differences in braking behaviour
Vehicle performance varies significantly – need for improved minimum standards
![Page 5: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/5.jpg)
VehiclesSecondary Safety
Major improvements in crashworthiness driven by EuroNCAP and legislation
Accident data shows a reduction in fatality rates of drivers of 22%
Passive safety is a mature science
Further big reductions expected from improved compatibility, side impact performance,Pedestrian protection

Learning from other transport modes
![Page 7: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/7.jpg)
Aviation – the safest transport mode
Crashes are rare
Pilots well trained and monitored
Automatic systems reduce conflicts
Vehicles controlled in position and speed
Heavily controlled andregulated

Integrated Safety on Roads
Strong industry led set of projects
Provides integrated approach to active safety
Total EU investment ~ €250m (50%)
Specifies direction of technology development
![Page 11: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/11.jpg)
Casualty reduction and eSafety
![Page 12: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/12.jpg)
Accident data
Accident data forms the foundation of road and vehicle safety management process
Macroscopic data shows casualty trends
In-depth data supports countermeasure development
Continuous in-depth researchinto accident and injury causation is needed to identifypriorities and develop countermeasures
![Page 13: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/13.jpg)
Accident Priorities
Primary risk factors from accident data
1. Speed 30% of road deaths
2. Alcohol 17% of road deaths
3. Seatbelt 30% of road deaths
![Page 14: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/14.jpg)

Prioritisation of ITS technologies
Based on maximum casualty reduction
Take account of- Numbers of relevant crashes- % reduction of relevant crashes- Confounding factors – especially
human factors
No systematic estimates of casualty reduction for ITS
![Page 16: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/16.jpg)
How do we evaluate active safety systems?
Problems- No systematic method of
assessment- Insufficient in-depth
representative data for EU 25- Countig crashes that didn’t occur
(near misses, naturalistic driving)
![Page 17: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/17.jpg)
Casualty reduction methods
Standard approaches are
1.Engineering2.Enforcement 3.Education
How is ITS being used to improve these techniques?- Many engineering
measures- No enforcement- Little education

EU-level approaches to casualty reduction
Wide range of fatality rates in EU 25- Some countries need traditional casualty
reduction methods- Others need new methods including ITS
Best practise is to have an integrated road and vehicle safety management approach
There are opportunities to improve the coordination of road and vehicle strategies at EU-level
![Page 20: Www.vsrc.org.uk Pete Thomas Professor in Road and Vehicle Safety Vehicle Safety Research Centre Loughborough University, UK A review of ITS and their safety.](https://reader035.fdocuments.in/reader035/viewer/2022062619/551520c4550346a87d8b519d/html5/thumbnails/20.jpg)
Conclusions
1. There are still considerable gains available from improved passive safety
2. ITS has the potential for further casualty reduction
3. Countermeasures should be targeted for maximum casualty reduction
4. eSafety initiatives should be properly integrated within the wider road and vehicle safety context
