Yonge & Alcorn

Traffic volume8-hour count · Mar 29, 2022

This is a three-leg intersection with no east leg. The south leg carries the load — 3,471 northbound vehicles, or 49% of everything entering — while the west leg brought 259. Most cyclists arrived from the north (140 of 270). The morning and afternoon peaks are nearly equal: 1,026 vehicles in the hour from 7:45 a.m. and 964 from 5:00 p.m. Heavy vehicles made up 4.0% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count is 5 years old — treat it as a snapshot of 2022, not today's volume. It was an 8-hour count, which is not directly comparable with the 14-hour counts the City has used since September 2023.

Peak hours: 1,026 vehicles in the hour from 7:45 a.m. and 964 from 5:00 p.m. (approach figures are vehicles entering from that leg over the whole count — one day's traffic, not an annual average).

The KSI record for this intersection is empty back to 2006.

A collision counts when its recorded location is within 65 m of the centreline node, intersection-related or not. KSI = killed or seriously injured, the basis of the danger rankings; records can lag a year or more, so the current year is outside the window. How collisions are counted.

Toronto Police place no thefts from vehicles and one bicycle theft at this intersection in 2016–2025.

Police offset every occurrence to the nearest intersection before publishing, so these are thefts on the streets and premises around this node, not necessarily at the corner itself. Other offences are published by neighbourhood only — see Yonge-St.Clair.
