Roadside Design

Roadside Design

Instructor

Louis B. Stephens, Jr., P.E., B.S.C.E.
Louis Stephens is the owner of LBS Consulting, a transportation engineering consulting firm. He has managed numerous highway safety research and training projects including functional requirements for highway safety features, work zone traffic control, guardrail warrants for low volume roads, and roadside design. Mr. Stephens has spent much of his 33 years experience involved in highway safety engineering. As a highway engineer with the Federal Highway Administration, he managed several nationwide highway safety training initiatives.

 

Mr. Stephens developed the Roadside Design training course for the Federal Highway Administration which he conducted for state highway agencies throughout the country. He is a licensed engineer in California and Florida and is a member of ASCE, NSPE, and the Institute of Transportation Engineers.

Course Description


Every year tens of thousands of people die or are seriously injured in vehicle collisions with objects on the roadside, such as signs, trees, concrete barriers, or guardrails. Many deaths and injuries could be prevented if roadsides were designed differently or if these potential hazards were placed in safer and better locations. This seminar takes you step-by-step through the new 2002 AASHTO Roadside Design Guide, generally recognized as the national standard for roadside design. Learn how to apply these guidelines to design the safest and most cost-effective roadsides for both highways and low volume roads. The following topics are covered in detail:

  • Clear zone concept, its determination and application
  • Location and design of sign and luminare supports
  • State-of-the-art information on selection, design, and location of roadside and median barriers, crash cushions, and bridge railings
  • Temporary roadside barriers associated with construction and maintenance
  • Benefit/cost analysis to determine best roadside design
  • Roadside safety needs will be tempered with the practical considerations of cost and suitability. Issues such as environmental impacts, aesthetics, costs, and driver needs are also examined

Many decisions that are made and implemented during road construction, rehabilitation and/or maintenance operations directly affect the safety of the roadside. A few dollars spent ahead of time in planning and maintaining the roadside environment can actually save your community, organization, or client millions of dollars annually by substantially reducing highway deaths and injuries, thereby limiting liability exposure and related costs.

Day One


The morning provides an overview of roadside safety and the roadside environment. Participate in a clear zone design workshop to learn how to design a recovery area free from potentially dangerous obstacles; determine which objects should or should not be in a clear zone. Economic analysis is introduced as a tool to help you design the best roadside within your budget. The afternoon session presents an overview of drainage features, breakaway devices, and crash cushions, followed by selection and location of traffic barriers.

Day Two


Learn about layout design of barriers, and participate in a roadside design workshop to gain hands-on experience which can be readily applied to your next project. Examine ways to assess systemwide needs and establish priorities. Roadside barriers for use in construction and maintenance are also covered.

Who Should Attend


  • Consulting Engineers
  • Federal, state, and local highway and transportation agencies
  • Professionals dealing with low volume road design operations or maintenance

Whether you are a novice or experienced in highway design, maintenance, or operation, you will get all the latest information you need to design cost-effective, safer roadsides.

Special Features


You will receive workshop/seminar materials and a copy of the AASHTO "Roadside Design Guide", valued at $120. You can also purchase a copy of this book at a discounted price at www.civilbooks.com.

    Attendees’ Comments

     

    “The course was a common sense approach to designing roadside barriers and made the calculations easier to understand.”
    -Robbie Zephirin, Transportation Engineer, Felsburg Holt & Ullevig,
    Centennial, CO

    “All engineers should attend this class prior to taking responsibility for a roadway design project.”
    -Bryan Parsell, Washington Group, Carson City, NV

    “Well done seminar. Very informative instruction on a subject that could be a bit vague.”
    I-Ben Wardell, Civil Engineer, Parsons Brinckerhoff Inc., Denver, CO

    “The seminar provided valuable explanation of the application of various barriers and end treatment and reasons for choosing one style over another.”
    -Dave Harms, Felsburg Holt & Ullevig, Centennial, Colorado

    “The course provided insight into evaluating clear zones dealing with super elevations and high speed roundabouts.”
    -Jeremy Colip, Felsburg Holt & Ullevig, Centennial, Colorado
