Permanent working group under the umbrella of ITF and OECD
Network of experts, representing key road safety stakeholders
Mission
Networking for road safety professionals
World standard road safety database
Data analysis

4. IRTAD 80 members or observers from 40 countries
The database includes validated data from 32 countries
IRTAD-LAC 4

5. Wide variety of Members:
Administration, research organisations, NGOs, International organisation, industry, etc…
Open to all countries
Main outputs
Forum of exchange – 2 meetings / year. 1 conference / 3-4 years
Annual report
Research and analysis
Database
Outreach activities

6. The IRTAD Database National aggregated data on traffic and road safety
Currenly includes 32 countries (validated data)
Data from 3 countries currently under review
Progressively include more countries while keeping a high priority on data quality
The IRTAD database is a tool for:
Safety performance monitoring
International benchmarking
The expert network behing the database is as important as the data themselves (understanding methodologies, data collection, defintions, limitatons of the data, underreporting issues, etc.)

7. Content of the IRTAD database
Crash data: fatalities, injury crashes, hospitalised, injuries
By road type (motorways, urban roads, rural roads)
By road user (pedestrians, cyclists, car occupants, PTWs, others)
By age
By gender
By seat position in the car
Exposure data:
Vehicle –kilometres
Modal split
Vehicle fleet, by type of vehicles
Population
Driving licences
Other safety data
Seatbelt wearing rates
Helmet wearing rates
Review of the content – ongoing
SPIs
Review of user categroy : ebikes ? Trucks ?

8. The IRTAD Annual Reports
2018 summary report will be released in Leipzig.
Will be completed by 40 country reports
2017 is available on line

9. Evolution in road deaths – 2010-16

10. Evolution in road deaths (32 countries)
Provisional data for 2017 are encouraging.
Fatalities decreased in 21/30 countries

11. IRTAD Research: Alcohol related casualties in official crash statistics
Based on official statistics from the 45 countries surveyed, an average share of 21.8% of fatal crashes are alcohol related.
Great variations, ranging between 5% and 35%.
The real number of alcohol-related road casualties is higher.
Official statistics tend to underreport alcohol-related crashes and casualties, only based on police data
Better insight is need to adequately assess the extent of the problem of alcohol and design and implement appropriate responses.  

12. IRTAD Research – Speed and crash risks
Aim:document the relationship between vehicle speed and crash risks.
Based on:
Literature review
Case studies from 10 countries: changes in speed limits or wide scale introduction of automated speed control
Speed has a direct influence on crash occurrence and severity
This relationship has been captured in various models, most notably Nilsson’s “Power Model”. :
a 1% increase in average speed results a 4% increase in fatal crash frequency.
The cases confirmed the power model

13. Speed and crash risk: Recommendations
Reduce the speed on roads as well as speed differences between vehicles
Set speed limits based on the Safe System principles
Implement compensation measures where speed limits are increased
Automatic speed control has proven its effectiveness in reducing speed
To be published in the coming days

14. Outreach activities
Co-operation with OISEVI, the Ibero American Road Safety Observatory
IRTAD LAC database
ITF/World Bank / FIA agreement on regional Observatories
Africa
Twinning projects and data review missions
