Roadway Safety Improvement Projects

The Traffic & Safety Engineer handles the Roadway Safety Improvement Program (RSI). The RSI program has $10.5 million Federal Hazard Elimination Funds allocated to it for implementing improvements at locations on public roads where there is an accident history. Depending on the size of the improvement, 10 to 15 projects are programmed each year in the RSI program. There is a match ratio of 90/10, where the local entity is required to pay the 10% match.

South Dakota Strategic Highway Safety Plan

The mission of the South Dakota Department of Transportation (SDDOT) is to provide a safe and efficient transportation system. In order to provide a safe transportation system, the SDDOT and the South Dakota Department of Public Safety, in partnership with the Federal Highway Administration (FHWA), found it necessary to update the 2007 Strategic Highway Safety Plan (SHSP). The updated plan, guided by the safety vision statement of: Every Life Counts: Partnering to Save Lives, identifies various strategies and options intended to reduce the fatal and serious injury crash rate 15% by 2020.

Centerline Rumble Stripes

The South Dakota Department of Transportation will be placing Centerline Rumble Stripes (CLRS) on stretches of state highways with high traffic numbers. CLRS are a proven countermeasure to reduce the risk of cross centerline crashes such as head-on and side-swipe collision. Although these types of crashes represent a low number of overall crashes in South Dakota, they represent a significant number of severe crashes due to the high speed differential. CLRS are a low cost safety improvement that have been shown to reduce cross centerline crashes by 50 percent. To learn more about CLRS in South Dakota, click here.
