I reiterate our findings on space allocation in the roadway (97.7% cars : 2.3% bikes), the street (79.6% cars : 18.8% sidewalks : 1.6% bikes), the disparity between space and mode share, and our finding that more bike infrastructure is correlated with decreased rates of crashes involving cyclists.

Clearly communicating about street space is evidently important in understanding cities. I appreciate Metro Morning providing the opportunity to talk over this topic in another urban context. We would love to extend this analysis to other Canadian cities.

Hopefully we'll have the opportunity soon, we'd like to see how the numbers change with updated data. Thank you for your interest!

The disparity between the proportion of trips by cyclists, and the proportion of space given to their infrastructure, relative to cars, seems to be especially resonant, so I threw together this map based on the study's data for another form of illustration (though, see the maps in the study).

We found that in Montréal, streets are overwhelmingly allocated to cars, at the expense of cyclists' space (97.7% to 2.3%). This is true even in boroughs we tend to think of as cycling friendly. In the Plateau, 22% of trips are cycling trips, but they only have 4.7% of the roadway.

All this to say, one of our main goals for this study was to communicate clearly about street space - and it seems that our framing strongly resonates.

Street space frames our experience of the city. It matters deeply to people; no wonder there's so much passion here, for better or for worse.

Street space is overwhelmingly allocated to car infrastructure, yet any efforts to reallocate space to other transport modes is hotly contested. Turns out, even with radical proposals to increase micromobility infrastructure space, drivers need not worry – the cars are going to be alright.

We also model scenarios: what if we doubled all the bike lanes in Montréal? Still, in no borough would cars have less than 90% of the road, space per driver would fall by just -0.154 sq. m/traveller, but micromobility area would increase to +4.447 sq. m/traveller.

Boroughs with more cyclists have a worse ratio; in Plateau, drivers have 3.36 sq. m/traveller, compared to 1.51 sq. m/traveller for cyclists. We present several measures for communicating this inequality in street space allocation, look at spatial distribution, relationship to socio-demographics...

We measure how street space is divided between transport infrastructure in Montréal. Between cars and micromobility, cars are given 97.68% of space to micromobility's 2.32%; per traveller, cars are given 5.8 sq. m/traveller to micromobility's 4.54 sq. m/traveller.
