“Taxonomy of Roadside Hardware“

TRB First International Roadside Safety Conference,

June 12-15, 2017, San Francisco, CA

Since the early 1970’s,

AASHTO ARTBA AGC

Task Force 13 has

worked to standardize

roadside hardware

through developing

“guides.”

Printed guides in

1973 …

1979 …

1995 ….

Johnson and Ray,




Today:

Online Guide

Johnson and Ray,




• Today there are really NINE guides

• Components Original

• Barrier Hardware

• Bridge Rail Systems

• Transition Systems

• Sign Support Systems

• Luminaire Support Systems

• Work Zone Systems Under development

• Crash Cushion Systems Under development

• End Treatment / Terminal Systems Under development

• Standardization of nomenclature

• System to system compatibility and interactivity

• Listing of components used in systems systems used by components

• Online accessibility no need to install anything

• Browser-based interface removes compatibility issues between computer types

(Windows, Macintosh, Linux, iOS, Android, etc.)

• Constant and continual updates

• THE definitive guide, recognized by RDG; Free to all!

4th Edition Roadside Design Guide

The AASHTO-Associated General Contractors

of America (AGC)-American Road and

Transportation Builders Association (ARTBA)

Joint Committee Task Force 13 report, A

Guide to Standardized Highway Barrier

Hardware is a depository of engineering

drawings for a multitude of guardrail

components and systems. Each system is

given a unique designation used to catalog the

different systems and variations of each

system. A web site has been established for

each supported system, and is available at

http://www.aashtotf13.org

Section 5.1.2:

Johnson and Ray,




What is a “Designator”?

An identifier that unambiguously

refers to a particular part or system.

Johnson and Ray,




Category – System or Component

Function – Kind of System or Component

Type – Material / Compatibility / More Specific Information

Sequence # - Assigned Numerically

Option – Assigned Alphabetically

Each Designator Contains:

Adoption of guide designators by State

DOTs and Maintenance Divisions would:

• Reduce reliance on “institutional memory”

• Standardize guidelines for repair or

replacement, reducing inconsistencies

• Reduce the use of outdated information

• Reduce installation and maintenance errors

• Improve hardware inventory asset control

• Improve hardware system compatibility

information

The online system and component guides are maintained by Roadsafe, LLC with a support contract provided by Task Force 13.
