Roundabouts enhancing your drive on Regional roads

Lloydtown-Aurora Road and Keele Street

In 2018, staff completed a traffic operation assessment of the three existing roundabouts on Regional roads. The results show that motorists are experiencing up to five seconds less delay during critical peak periods and collisions have significantly reduced, particularly at Lloydtown/Aurora Road and Keele Street, from an average of seven collisions per year down to two; a 71 per cent reduction.

The first Regional roundabout was installed in fall 2013 at the intersection of York/Durham Line and Durham Regional Road 5 in the City of Markham.

Before/After

Before and after roundabout

Prior to installation of the roundabout, the junction of York/Durham Line and Durham Regional Road 5 was irregular in configuration, consisting of a T-intersection with a ramp that facilitated traffic movement to and from the north on the York/Durham Line and to and from the east on Durham Regional Road

In addition to the technical benefits, roundabouts provide an opportunity to act as a gateway for communities, and inform motorists of a transition from rural highway to urban community.

Since 2008, three roundabouts have been installed in York Region. Based on industry studies, converting a stop-controlled intersection to a roundabout can reduce overall collisions by 40 per cent and severe collisions by 75 per cent.

York Region will continue to consider roundabouts when reviewing intersection improvement opportunities.
