The objectives of the international Common Methodology for In-Depth Motorcycle Crash Investigations are to conduct motorcycle crash investigations that are:

1. On-scene, at or near the time of the accident
2. In-depth investigation and analysis
3. Multi-disciplinary: engineering, medical, motorcycle-qualified investigators
4. Multi-level
5. Include crash causation as well as injury causation factors
6. Include human, vehicle, and environmental factors and all possible interactions
7. Include identification of countermeasures
8. Applicable to all powered two-wheel vehicle crashes
9. Recommended to use sample sizes of at least 100 crashes per sample area per year
10. Include collection of concurrent exposure data
11. Specify a minimum level and type of academic qualification, motorcycle riding experience, and special investigation team training
12. Able to provide and audit path between the raw data and the final results
13. Reproducible from team to team
14. Based on unbiased sampling, results, and interpretations
15. Useful for comparison between sample areas and countries
16. Based on a census of qualified motorcycle crashes meeting sampling criteria
17. Are from a sampling period covering 24 hours per day, 365 days per year
18. Require standardized, minimum statistical analysis
19. Result in final databases that have a common structure and format

The Organization for Economic Cooperation and Development (OECD) Common Methodology also requires analysis of the population-at-risk to coincide with investigation of the crash population. Large-scale data sources such as departments of motor vehicles can be surveyed and compared to the population-at-risk identified through concurrent exposure data collection. However, exclusive reliance on these data sources will not define the true population-at-risk.

The objectives for exposure data collection are to precisely define:

• Population-at-risk
• Traffic characteristics
• Land use characteristics
• Vehicle characteristics
• Historical perspectives
• Data requirements
• National representation
• Countermeasures applications
• International correlation
