In a 1999 paper, Weyrich and Lind argue that judging transit in North America by overall transit modal share is misleading, as most of the urban population is either not served by transit or served poorly. They suggest it is more appropriate to consider transit usage on transit-competitive trips. In light of this, I decided to investigate the modal split between transit and private vehicles on a transit-competitive corridor in the Region of Waterloo.

The proportion of overall trips in the Region of Waterloo taken on transit is perhaps 4%. But what about corridors with frequent transit?

There is really only one such corridor in the entire region – King Street in Kitchener-Waterloo. Between the Charles Street Terminal in Kitchener and University Avenue in Waterloo, Route 7 buses can be counted on to appear every 8 minutes or better from morning to evening. In addition to the 7, the iXpress route also runs along the same corridor, with 15 minute service. No other corridor has service better than every 12-15 minutes.

So on the morning of Monday, November 23, I set up on King Street right at the Kitchener-Waterloo border (between Union and Mt. Hope streets) with a clipboard and a video camera, and recorded trips between 7:30 and 8:30 am. It was overcast and foggy, with temperature between 1°C and 4°C. At the time I recorded all non-motor-vehicle trips, and the number of people on each Grand River Transit bus. GRT buses have 35-40 seats, but people rarely use all seats, so a bus with some standees can be expected to have around 35 people. Crush load is around 70-80 people. I used these figures to estimate the number of people on each bus as a multiple of five.

I counted other vehicles afterward on video, with one category for private vehicles (motorcycles, cars, and light trucks that weren’t obviously commercial) and one for all other vehicles. These included work vans, taxis, delivery trucks, transport trucks, dump trucks, and non-GRT buses, with a few one-offs.
