A Detailed Cost Breakdown of the Roadway Worker Protection System, Including Labor and Technology Cost.
Sacramento, California, United States
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.
The following summarizes the cost measures for the system:
