Underhill & Cassandra (South)

Traffic volume14-hour count · Oct 8, 2024

This is a three-leg intersection with no east leg. The north leg carries the load — 3,899 southbound vehicles, or 49% of everything entering — while the west leg brought 769. Morning rush is the busier period: 1,013 vehicles in the peak hour from 8:00 a.m., compared with 783 from 5:00 p.m. Heavy vehicles made up 3.7% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count is 2 years old; the City recounts intersections on an ad-hoc schedule, so volumes may have shifted since.

Peak hours: 1,013 vehicles in the hour from 8:00 a.m. and 783 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).

Collisions 2016–2025 · within 65 m

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.

How fast traffic moves here

The City's counter on Cassandra Blvd between Dr. Daniel Hill Park Trl and Redwillow Dr (145 m away) recorded an average of 37 km/h in its 24-hour count in October 2023; 85% of drivers were at or under 47 km/h. That segment carries about 1,500 vehicles a day. Underhill Dr between Royal Doulton Dr and Beveridge Dr measured slower: 38 km/h on average and an 85th percentile of 45 km/h (Nov 2020).

Midblock counts are automatic counters laid across the road for one to seven days; 85% of drivers were at or below the 85th-percentile speed. A reading is not the speed through the intersection itself, and posted limits are not in the count data. How speeds are read.

Toronto Police place one theft from a vehicle and no bicycle thefts 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 Parkwoods-O'Connor Hills.
