Crash Data

Crash research and data collection tries to answer a

basic set of questions regarding traffic crashes and their

outcomes:

Who, What, When, Where, Why and How?

Data Qualities Timeliness - Is the data available when you need it?

Completeness - Are you collecting the kinds of data that adequately address the

problem?

Accuracy - Reliability of data. Quality Control.

Accessibility - Who are the main users of the data? Data dissemination.

Uniformity - Can data be shared with other systems?

NHTSA Global Road Safety Agenda

NHTSA will be a global leader in road traffic safety sharing its knowledge and expertise.

NHTSA will maintain its leadership and influence in international organizations that are stakeholders in regional or global road safety.

In particular, provide technical assistance to develop traffic safety data record systems

Example

APEC – (Asia - Pacific Economic Cooperation) Motivate – Encourage APEC economies to take

necessary steps to improve their data.

Master Plan – Work with volunteer APEC economies to develop ways to improve their data.

Assessments – Evaluate existing systems.

Blueprint – Develop detailed design / redesign plan of action.

Implement – Perform or carry out plan of action.
