IBI Group’s
2010 Operational Review of the Hamilton Street Railway focused on user load in the weekday afternoon peak period (3pm-7pm), with the bulk of the ridership survey conducted in Nov 2008 (the remainder of samples were concentrated between Sept-Nov and Jan-Apr). As a result, there appears to be no recent, rigorous third-party information regarding HSR ridership outside of the post-secondary school year – or, for that matter, on weekends. The peak period referenced in the IBI report features the highest service frequency of the entire week – an average of 30 buses per hour – but that’s obviously atypical of the system’s performance. Even so, there is reason to be encouraged.
Studying traffic frequency on the HSR’s schedules for routes 1/5/10/51 offers some broad-brush hints as to existing ridership.
Sept-Apr
Mon-Fri: Average of 21 buses an hour (30% below peak)
Sat: Average of 12 buses an hour (60% below peak)
Sun: Average of 8 buses an hour (74% below peak)
AFAIK, 51 University doesn’t run during the summer, leading to a modest decline in weekday frequency.
May-Aug
Mon-Fri: Average of 18 buses an hour (40% below peak)
Sat: Average of 11 buses an hour (63% below peak)
Sun: Average of 8 buses an hour (74% below peak)
From May to August, it seems safe to assume that ridership among the postsecondary cohort would also dip. Unfortunately, the HSR’s limited operational budget makes it impossible to know how much latent demand they are failing to capture even now through the disincentive of mediocre service levels.
Metrolinx’s 2010
Benefits Case Analysis uses reference capacities of 90 passengers per articulated bus and 1,950 riders per operating hour of a single-car train on a four-minute headway. In other words, 15 single-car trains gives you the approximate ridership capacity of 21 articulated buses. (Coincidentally, this is the current average hourly service frequency from Monday to Friday during the school year, though obviously not all 1/5/10/51 buses are artics.)
