Service Reliability on 65 Parliament: September 2021

This article continues a series reviewing service quality on some of the TTC’s shorter routes that generally escape notice when buses like Dufferin and Finch come under fire for erratic operation.

Overview

65 Parliament is a very short route operating from Castle Frank Station on Line 2 BD south to The Esplanade. The 2022 Service Plan proposes extending the route south to Queens Quay to the loop at Corus Quay serving George Brown College.

The service design during September 2021 is shown below:

Although the scheduled headway varies from 11 to 20 minutes, the actual headway operated can at times be well over half an hour either because buses are missing from the route, or because the limited number of vehicles on the route are running in pairs.

In the headway charts below, I have extended the vertical scale from the 0-30 minute range used in past articles to 0-60 minutes so that the data points will be visible.

Southbound From Castle Frank Station

The screenline for the data here is on Bloor Street west of Castle Frank Station.

In spite of this route being short, there is a wide dispersion in headway values as the charts show. In a pattern seen on other routes, the standard deviation of the headways (dotted lines in the first chart) lie between 0 and 5 minutes for the first few hours of service, but rise substantially thereafter. This is a measure of the degree to which headways diverge from the mean value.

Those means show their own variation on a week-by-week basis indicating that the number of trips (and hence the average headway) was not consistent across the month. Day by day breakdowns are in the rest of the charts.

Days with very wide gaps and bunching are not rare oddities, but are a common situation on this route.

Northbound From Front

The screenline for the data here is on Front Street just east of Berkeley which is the start of the south end loop.
