1. First International Roadside Safety Conference June 12, 2017
Standardization of Roadside Safety ISPE Process Using Data Dictionary for Pre- and Post-Crash Information
First International Roadside Safety Conference
June 12, 2017

2. Background FAST Act Requirement (2015)
Section 1429: Techniques to identify and document roadside safety hardware devices.
Resulting in the ongoing FHWA Hardware ID Project
Determine available hardware ID methods.
Provide analysis of available methods.
Evaluate for ability to convey information, withstand roadside conditions, and connect to existing systems.

3. Background Knowledge gap identified…
How much storage space and what information do we need to store on a tag?

4. Project Overview TTI Center For Transportation Safety Scope
Funded by Texas Legislature (since 2001)
$5 million of research each year
Scope
ISPE Framework Development
ISPE Data Dictionary
Hardware ID Crash Testing

5. Project Overview
Review of Data (longitudinal barriers) in ISPE Literature
Develop data categories, fields, and attributes.
Pre- and Post-Crash
Develop all inclusive data dictionary in traditional format

6. Literature Existing ISPE Data in Literature
