RSAP - Roadside Safety Analysis Program

Slide background

Stormwater

RSAP is the primary tool endorsed by WSDOT for the evaluation of mitigation alternatives for Clear Zone Objects. Belsby Engineering works closely with Utilities and WSDOT to analyze the location of existing utilities within WSDOT right of way. We prepare control zone calculations to determine limits of the control zone at a particular object. The Roadside Safety Analysis Program (RSAP) is then used to analyze objects located within the control zone. Location II objects with no accident history are analyzed in their existing locations and compared to location specific alternative solutions. A cost-benefit analysis is performed through RSAP, and a recommended solution is obtained. The RSAP recommended solution is then used as a variance alternative for WSDOT.

WSDOT recently removed the 5/15 rule from their Utilities Manual. The only option other than object relocation is using RSAP analysis to justify leaving an object in its existing location. The WSDOT Utilities Manual requires RSAP analysis be stamped by a professional engineer. Belsby has fully qualified staff available and ready to perform RSAP analysis.

Our staff’s strong background in traffic and road engineering as well as surveying gives us the tools needed to properly evaluate and analyze right of way and the objects located within it. Our understanding of WSDOT’s needs in working through the RSAP analysis allows us to deliver the most efficient and cost effective product to our client.
