TRB conducted a webinar on March 27, 2013 from 2 p.m.- 3:30 p.m. ET that showed participants how to use the Roadside Safety Analysis Program (RSAP). Contact Reggie Gillum at
RGillum@nas.edu for instructions on receiving a link to the webinar recording.
The Roadside Safety Analysis Program (RSAP) was developed to update and enhance the cost-effectiveness analysis procedures in the AASHTO Roadside Design Guide. The program and its interface have recently undergone an extensive upgrade to incorporate new research results, enhance computing capabilities, and improve ease of use.
RSAPv3 assists in performing roadside safety economic analyses. RSAPv3 incorporates advances in roadside safety in the decade since its previous version; this required rewriting the code and developing new methods and techniques. An encroachment-based approach, RSAPv3 divides collisions into three independent events:
- The encroachment, when the vehicle first leaves the road;
- The traversal of the roadside, where hazards may be located; and
- The severity of the crash when a vehicle intersects a roadside hazard.
RSAPv3 performs this series of calculations many times, simulating tens of thousands of encroachments for a typical roadway segment and estimating the crash costs of each possible encroachment. After generating all the encroachments and the estimated crash costs, the program produces an estimate of the total crash cost for the segment. RSAPv3 can evaluate up to five design alternatives on up to 20 highway segments and can compare the benefit–cost ratio of each alternative. The alternative that makes best use of funds is presented to the user at the end of the analysis.
Participants are not required to purchase or download the RSAP program to successfully participate in the webinar. The final
NCHRP report may be downloaded for free on the TRB website. The RSAP update is an AASHTOWare program and may be purchased through the
AASHTO bookstore.
Webinar Presenters:
- Malcolm Ray, Roadsafe LLC
- Christine Carrigan, Roadsafe LLC
Moderated by: Chuck Plaxico, Roadsafe LLC
Webinar Outline:
- Getting started with RSAP (Malcolm Ray): Participants will be shown where to obtain the software, manuals and examples and how to download and install the program. The basic layout of the software and instructions for navigating through the input screens will also be presented.
- Example Problem (Christine Carrigan): Participants will be shown step-by-step how to collect the information needed to perform an analysis, how to represent that information using the input screens in the program, and how to execute the analysis and interpret the results.
- Staying in Touch with the RSAP World (Malcolm Ray): Participants will be shown where they can get additional resources and how they can ask questions or make comments on the software. Collaborating and sharing with other RSAP users is one of the best methods for developing expertise with the software.
The first 60 minutes of the webinar is for presentations and the final 30 minutes is reserved for audience questions.
Learning Objectives:
- To understand how to locate, download and install the RSAP software.
- To perform a simple roadside design analysis and extend and the analysis to a wide variety of other roadside design problems.
