A review of ITS and their safety benefits Presentation to ETSC Best in Europe ConferenceBrussels21-22 February 2006
1
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?
2
Conventional vehicle dynamics – braking, handling, cockpit ergonomics etc Primary NCAP – significant differences in braking behaviour Vehicle performance varies significantly – need for improved minimum standards
4
Vehicles Secondary 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
5
Learning from other transport modes
6
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 and regulated
7
eSafety Initiative
8
EU eSafety Initiative
Development , deployment and use of Intelligent Integrated Safety Systems Information and communication technologies Driving technology development Research funding Enabling actions (eg waveband allocation, eCall MoU) Coordinating Member state support eSafety link
9
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
10
Casualty reduction and eSafety
11
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 research into accident and injury causation is needed to identify priorities and develop countermeasures
12
Accident Priorities
Primary risk factors from accident data Speed 30% of road deaths Alcohol 17% of road deaths Seatbelt 30% of road deaths
13
eSafety Technology Roadmap
Priority vehicle based technologies ESC (Electronic Stability Control) Blind spot monitoring Adaptive head lights Obstacle & collision warning Lane departure warning Priority infrastructure based technologies eCall Extended environmental information (Extended floating car data) RTTI (Real-time Travel and Traffic Information) Dynamic traffic management Local danger warning Speed Alert
14
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
15
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)
16
Casualty reduction methods
Standard approaches are Engineering Enforcement Education How is ITS being used to improve these techniques? Many engineering measures No enforcement Little education
17
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
19
Conclusions
There are still considerable gains available from improved passive safety ITS has the potential for further casualty reduction Countermeasures should be targeted for maximum casualty reduction eSafety initiatives should be properly integrated within the wider road and vehicle safety context
