**Washington, DC**

##          Outline

***We will discuss****:*
*A Overview of National Center for Statistics and Analysis*
*Critical Nature of Data*
*Goals of National Highway Traffic Safety Administration*
*Examples of Improving Data*

## NHTSA and Data

*NHTSA and the highway safety community overall are very data driven*
*Data are used extensively for:*
*Basic research*
*Identifying problem areas*
*Identifying program and rulemaking needs*
*Developing and evaluating programs, rules and standards*
*Evaluating new technologies *
*Allocating grants*
*Implementing GPRA*

## What is NCSA?

*Provides:*
*data collection, data analysis, and data dissemination on real world crashes and traffic records*
*To:*
*NHTSA , but also to:*
*other parts of DOT*
*outside stakeholders*
*automobile manufacturers*
*universities*

## Ingredients of an Effective Crash Data Collection Program

## Why Are Data Critical?

- Building A Data Collection System

**1) Problem Identification**

**2) In Depth Understanding**

**3) Approach To**
**Addressing Problem**

**4) Development/Implementation**
**Of Approach**

**5) Evaluation**

**6) Adjustments**

**Notes:**
NCSA data is used to...    improve the safety of vehicles    improve highway safety    improve driver and occupant safety
Resulting in a steady 20 year decline in the fatality rate! 

## NCSA’s Data Collection Network

## 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?

**Notes:**
Meeting deadlines for release of data filesIs the data available when it is most needed?Time Sensitive / High Profile DataRollovers, Fifteen-Passenger Vans, Tire Pressure, Daytime Running Lights, Air Bags

## 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.
