Züm

Züm (/zuːm/, pronounced Zoom) is a bus rapid transit system for the suburban city of Brampton, Ontario, Canada, northwest of Toronto, operated by Brampton Transit. Three routes extend into the Cities of Mississauga, Vaughan, and Toronto, with the first corridor having started service in fall 2010.

Phase 1 became fully operational by fall 2012. A key aspect of the Züm plan is increased service on supporting local corridors. Unlike other, similar, services and partly due to Brampton's diagonal geographic position relative to Toronto than other suburbs such as Mississauga or Vaughan, many Züm corridors will overlap significantly with other agencies' services, requiring more complex, co-operative planning between neighbouring cities. During the planning of this bus rapid transit system, Züm was called Acceleride.

Buses usually operate in mixed traffic, although Route 501 Queen uses the Highway 7 Rapidway, a busway built for York Region Transit's (YRT) similar Viva network, while travelling through most of Vaughan, and stops at all stations along YRT's Viva Orange route. Brampton Transit has a fare partnership agreement with York Region Transit that allows for boarding and debarking anywhere along the Viva Orange route, using Züm buses. This was particularly convenient during a labour dispute involving some contractors operating YRT resulting in the temporary suspension of Viva Orange.
