Summary Information

Through partnership with the Federal Transit Administration (FTA), the Sacramento Regional Transit District (SacRT) conducted a demonstration test of a secondary warning device for roadway workers in 2018. The commercially available secondary warning system consists of a roadway worker protection (RWP) system mounted in a rail vehicle and a personal alert device (PAD) worn by a roadway workers. This secondary RWP system design provides a visual and audible advance warning alert to train operators of workers ahead and a visual and audible advance warning to alert wayside track workers of approaching trains. A second phase of the project implemented the Employee in Charge Software System (EICSS) that uses smartphone technology to validate and authorize roadway worker access to specific sections of track.
