|
| 1. What Do Linked Data Tell Us?
|
| Linked data identify the types of injuries and the costs that result from specific driver, vehicle, and crash characteristics. |
|
| 2. What Do States Need To Implement CODES? |
- Computerized statewide crash and injury data (preferably edited statewide).
- Person and crash identifiers, including date of birth and specific location of the crash.
- Sufficient microcomputer (or workstation) capability to process large state data files.
- Staff members who are experienced in working with the crash and injury state data.
|
|
| 3. What Resources Are Available To Assist States?
|
| Technical assistance for states is available from NHTSA through CODES experts, who will advise how to obtain state data, resolve barriers related to confidentiality and privacy, and prepare the files for linkage. These CODES experts also provide assistance to establish an advisory committee to institutionalize data linkage, implement the probabilistic linkage software, perform the linkage, validate the linkage results, and assist in the developing of analytical uses for linked state data.
|
|
| 4. Who Directs CODES? |
- CODES Board of Directors, including the owners of the state data and responsible for all decisions related to confidentiality, management and release of the linked data.
- CODES Advisory Board, including the data owners and major users of the linked data who review and advise on applications of the linked data.
|
|
| 5. How will staff gain experience in working with the crash and injury state data? |
| CODES provides extensive on-site training in probabilistic linkage
|
|
| 6. Where will I get the necessary computer resources for linkage? |
| Funded by CODES.
|
|
| 7. How will CODES fit within existing state agencies? |
- State support of routine linkage of state data
- Use of linked data for traffic safety decision making
|
|
| 8. Are there other CODES links available? |
| Yes, state CODES links are included in the Related Download item "CODES States Directory" on the State Data Systems page.
