Motorcycle Crash Causation Study (MCCS) Frequently Asked Questions


Q: How long will the study last?

A: Data collection for the MCCS will continue through 2015. After data collection is completed, the MCCS team will develop a dataset, perform preliminary analyses, and deliver a final report in 2016.

Q: Who is paying for the MCCS?

A: The MCCS is primarily funded through the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). Further funding contributions were made by the National Highway Traffic Safety Administration (NHTSA) and the American Motorcycle Association. In addition, a Transportation Pooled Fund (TPF) Program study was established to enable State and local agencies to contribute additional funds.

Q: What is a TPF Program study?

A: The Transportation Pooled Fund (TPF) Program enables Federal, State, and local agencies and other organizations to combine resources to support transportation research studies. The TPF Program is supported and run through the Federal Highway Administration (FHWA). For more information about the TPF Program, go to http://www.pooledfund.org.

Q: Why are data only being collected in California?

A: The study funds only enable the team to conduct the study in one geographical region. The site selection process went through a thorough review to ensure that the chosen region would include a region with year-round ridership and a large population of motorcycle riders.

Q: How will cases be selected?

A: Through memoranda of understanding (MOU), local law enforcement agencies agreed to report all crashes involving motorcycles to the MCCS investigators. The investigators will follow up with investigations of each case. All no injury cases will be dropped, per the requirements of the Organization for Economic Co-operation and Development (OECD) protocol that the team is using as a standard for this study. In addition, the investigators will use other resources to follow up with no police-reported crashes by utilizing outside sources such as Web or newspaper reports. At an appropriate time, study investigators will review the collection methods to determine whether a stratified sample selection methodology is required to accommodate low-frequency crash types.

Q: How do participants know that their identity is safe?

A: Each participant in the MCCS will be given a certificate of confidentiality, which stipulates that members of the MCCS team cannot reveal, nor be forced to reveal the identities of any participants; not even under subpoena. In addition, all data will be stored on secure computers and servers with up-to-date security protection. Any documents, which are collected as part of the investigation process, that contain personally identifiable information (e.g., police accident reports) will be stored in a secure location until they can be destroyed at the end of the project. No personally identifiable information will be included in the permanent databases.
