CDIP Workshop

CDIP Technical Assistance

The CDIP provides direct technical assistance to a 

State’s crash database administrator or manager. 

A CDIP Technical Assistance Team (TAT) meets with 

the crash database administrator and staff to review 

current State practices and procedures for assessing 

crash data quality. Based on the TAT’s findings, a 

recommendations report is issued to the State.

CDIP Follow-up Consultation Services

The CDIP TAT will continue to provide consultation to 

the State regarding the recommendations and how 

to implement them. 

CDIP Financial Assistance

States that participate in the CDIP are eligible to 

receive funding from the FHWA of up to $50,000. 

This funding assists the State in developing and/or 

implementing one or more of the recommendations 

generated in the CDIP report. These funds require a 

State match of 20 percent.

Crash Data Improvement 

Program (CDIP)

Why Improving Your Crash Data 

Is Important 

•	 Improves problem identification and

evaluation of countermeasures.

•	 Provides a data driven basis for establishing

safety policies. 

•	 Improves a State’s ability to make decisions

regarding the best safety countermeasures

to apply to problems.

•	 Provides a basis for the justification of

highway safety projects.

FHWA can assist you in improving your 

State data process and systems through 

your State’s participation in the Crash 

Data Improvement Program (CDIP).

What is the CDIP Program?

The CDIP provides States with a means to measure 

the quality of the information within their crash 

database – performance measures and metrics that 

States can use to determine where their crash data 

stands in terms of:

•	 Timeliness

•	 Accuracy

•	 Completeness

•	 Consistency

•	 Integration

•	 Accessibility

The CDIP also gives States measures to assess 

deficiencies in each step of the crash data 

production process: 

•	 Crash data collection.

•	 Crash data reporting.

•	 Crash data processing.

CDIP Guide

FHWA developed the CDIP Guide to help States 

understand and appreciate the importance 

of good crash data. It is based on recognized 

noteworthy practices for assessing the quality 

of information in a State’s crash database and 

addresses the following questions:

•	 What is data quality and why is it important?

•	 What are the quality characteristics

(definitions)?

•	 What are quality metrics?

»	 How are they calculated?

»	 What are they measuring?

•	 What is the sensitivity of various metrics?

•	 How can quality characteristic benchmarks be

established?

The Guide also includes examples of management 

reports that assess quality measures.
