Pace Bus on Shoulders

Description

Pace buses leaving travel lanes to operate on shoulders during parts of the day or under specific traffic conditions. This passive system (action initiated by the bus driver) was successfully tested and is now operating on I–55 (left shoulder), Edens Expressway/I–94 (right shoulder), and I–90 (left shoulder). These lanes are often used by emergency vehicles. Surveillance of traffic conditions is used. Vision 2020 has driven innovation for Pulse program; the 2040 plan update is in progress. Additional corridors currently being studies for this system include I–57, I–290 and I–294.
