Illinois Tollway Lane 0 Management (I-90 Bus on Shoulders)
Description
Lane 0 management provides a dedicated bus lane where the left tollway shoulder would normally be found. Differing from the bus on shoulders program implemented on other regional facilities, this is not a typical shoulder. It is wide enough to accommodate a bus traveling at normal speed and will not be impeded by roadside structures. During congested times, it may be used to manage congestion as a component of the Tollway Active Traffic Management system. Bus use of the shoulder will be directed by the Tollway Active Traffic Management System, which will open and close the lane, rather than being decided by the bus driver.
The first location for Lane 0 management is on I–90. Lane 0 is used by the Tollway to accommodate Bus on shoulders on I–90, between Barrington Road and the Kennedy Expressway, and actively manages the use of the left shoulder by buses, by directing when buses are allowed to use the shoulder. The Tollway plans call for Active Traffic Management of all lanes and shoulders in this segment of I–90, with the possible expansion west to Randall Road in the future when warranted. Pace operates express buses from Randall Road to Rosemont Blue Line station operating on a managed shoulder and serving new park and ride lots being constructed at I–90 interchanges. Additional Lane 0 implementation is planned for other expressways/tollways in the region.
