Roadside Design

Regular Price $489.00 – 1 Year Access – 7 PDH Credits

Speaker / Author:
Louis Stephens, P.E., Orlando, FL

Today’s roadside engineer is greatly concerned with what happens to drivers, pedestrians, and construction workers when a car leaves the road, including the prevention and mitigation of crashes.

Join industry veteran Lou Stephens, P.E. as he covers the gamut of roadside design engineering. Weaving his 31 years of experience with a rich variety of charts, graphics, personal stories, photos, and text, Lou will teach you how to select the right roadside device for various design conditions, as well as proper roadside construction and maintenance techniques.

Supplemental Course Materials: It is recommended that you purchase Roadside Design Guide, the text used to teach the course.

The Civil Roadside Course Includes 6 Modules:

Roadside Design I: The Clear Zone
Roadside Design II: Economic Analysis
Roadside Design III: Roadside Barriers
Roadside Design IV: End Treatments to Breakaways
Roadside Design VI: Beyond Crash Cushions
Roadside Design V: Layout and Design

Each module provides 1.5 PDH

RD-01 Roadside Design I: The Clear Zone

Module 1 covers the basics of roadside design and discusses the clear zone in detail. Topics covered include: the clear zone standard and how to reach it; applying clear zones in construction zones; effects of curves and slopes on clear zone design; hazardous obstacles to consider; and other essentials regarding the clear zone and water, curbs, and drainage devices.

RD-05 Roadside Design II: Economic Analysis

Module 2 expands on the introduction to economics found in Session I. The used of Roadside and RSAP is explained and a example problem is presented. The economic analysis procedure presented is a valuable tool to making sound roadside design decisions. It can help agencies establish sound design policies and to prioritize improvement needs. It can help designers select the best improvement alternative and it can be used as a barrier warrant.

RD-02 Roadside Design III: Roadside Barriers

Module 3 covers basic information needed to make important design decisions, including how agencies perform cost analyses, the average cost of accidents, how crash severity is measured, and discounting. The course also covers roadside barriers, including classifications, potential hazards, warranting procedures, rigid and flexible systems, barrier placement, guardrail performance levels, and the effects of NCHRP 350.

RD-03 Roadside Design IV: End Treatments to Breakaways

In module 4 participants learn about the most hazardous part of the guardrail- the end treatment. The course covers dealing safely with the upstream end as well as past and present end treatments, their strengths and weaknesses, and safety recommendations for both designers and agencies. Other topics covered: median and gore terminal ends, including a median design for emergency vehicles; breakaway devices, including the essentials on single and multiple sign supports, horizontal slip bases, frangible couplings, and fracture systems; and breakaway device locations.

RD-04 Roadside Design VI: Beyond Crash Cushions

Module 5 of the this engineering PDH course covers crash cushions, bridge rails, median barriers, and work zones. Participants will learn what types of crash cushions should be used and when to use them as well as the criteria for using sand barrels. The bridge rail section covers retro-fitting bridges, making the safety walk safe, diminishing snag potential for vehicles, effectively upgrading bridge rail, and implementing safe transitions. The course teaches students about the safety shape median barrier, and finally covers work zones and their unique barrier designs, both protective and mobile for the workers who build our roads.

RD-06 Roadside Design V: Layout and Design

The final module in the series presents the layout and design procedure as presented in the AASHTO Roadside Design Guide. The presentation explains the design philosophy behind the procedure and an in-depth explanation of all of the design parameters. Mr. Stephens includes lots of practical tips and real-world examples for the designer.
