Parsons has been contracted by the San Diego Association of Governments to deliver an innovative pilot demonstration of Bus-On-Shoulder (BOS) operations on a limited access freeway using state-of-the-art technology for driver assistance. Through the deployment of Vehicle to Infrastructure Connected Vehicle (V2I CV), Lane Departure Warning (LDW), Blind Spot Warning (BSW), and Forward Collision Warning (FCW) technologies, this BOS pilot project will demonstrate that bus performance can be improved by allowing buses to drive on the freeway transit-only shoulder lane with minimal changes to the roadway. The pilot project will extend along Interstate 805 (I-805) from Chula Vista/South Bay to State Route 94 (SR 94) into downtown San Diego in both directions of travel. Upon completion of the pilot, all improvements to the freeway that were installed for the purposes of this pilot project will be removed.
Parsons is developing, integrating, and providing the following technology for this project:
LDW system alerting bus drivers that they are drifting into adjacent lanes.
BSW system alerting bus drivers of bus blind spots.
FCW system alerting bus drivers of forward obstructions.
Ramp metering Transit Signal Priority system holding vehicles at the ramps, as well as displaying. messages on Changeable Messages Signs at the ramps warning drivers of the buses
