The Three Card Monty: A Bus, Bike, and One-Seater Car plan for cities like Scarborough

One-seater electric automobiles may be on the rise, thanks to vehicle-sharing apps and range improvements in batteries. It is possible that these one-seaters will be a slothful and anti-social mode of transportation, like they are in Wall-E. Perhaps more likely, however, is that one-seaters will facilitate transportation that is actually more healthy and social than our existing four-wheel-dominated system. One-seaters may promote cycling, either via velomobiles (one-seater lightweight pedal-cars with an electric motor so that cyclists don’t have to break a sweat going uphill) or via the creation of more bike lanes in cities with relatively extreme climates (lanes which one-seaters would have mostly to themselves whenever the weather is not friendly to bicycles). One-seaters may also promote transit ridership, by making it easier to get to or from stations.

How then should cities prepare for one-seaters? While it would be nice if streets had three separate lanes for buses, bicycles, and one-seaters, this is not likely to be politically viable any time soon. Cities may need to be more creative, and more compromising, in seeking ways to promote one-seaters as an alternative for normal cars without unduly limiting transit or bicycle usage.

One possible way of doing this would be a sort-of seasonal three card monty, using a bus lane and an adjacent bike lane. When the weather is bad – say, during winter or a long heat wave – one-seaters would share the bus lane with buses and use the bike lane as a parking lane. This would allow a senior citizen to park close to his or her destination (or his or her bus stop), to avoid slipping on ice. It would also allow one-seaters to overtake buses at bus stops: if the bus pulls up to the curb at stops, a one-seater could pass the bus on its left. Similarly, it would give one-seaters the option of pulling over to let a bus overtake them.

When the winter or heat wave ends, the one-seater-parking lane would become a bike lane, usable by bicycles and one-seaters both. This would create less traffic for buses, at a time when the weather is nice enough to make walking to and waiting at bus stops a convenience. One-seaters and cyclists would however also be able to use the bus lane in order to overtake slower cyclists ahead of them, and to overtake buses at bus stops. Indeed, at times when buses do not run too frequently (nights, weekends), the bus lane would be left more or less open for one-seaters and the bike lane more or less open for bicycles.

It is true that bicycles would, comparatively, be the losers in this relationship. They would have to give up their bike lanes during the winter (or, in very hot climates, during the summer), and share them with one-seaters during the rest of the year. Nevertheless, given how few streets currently have bike lanes, cyclists might still benefit hugely from this relationship, particularly in climates in which bicycling tends to be a seasonal pursuit.


Let’s use a real-world example of where such a system could maybe be effective: Scarborough, Ontario. Scarborough is a suburb of Toronto, where the weather and distances people travel can be difficult for cyclists in the winter – and often in summer as well.

Unlike Toronto’s other suburbs, the shape of Scarborough’s coastline is slanted, giving the city’s main cycling path, the Gatineau hydro corridor (image above, map below), a diagonal shortcut route through the fairly strict grid pattern of the city’s streets. In a few years this corridor will be linked with the city’s newest half-subway line, the Eglinton Crosstown. The hydro/cycling corridor already connects, more or less, to a another subway line (via a short offshoot), a hospital, a university, and, via the Don Valley, to downtown Toronto.


Another, narrower diagonal hydro corridor, meanwhile, which nearly links up perpendicularly with the Gatineau around Lawrence East SRT station (which may eventually become a SmartTrack GO Train station, even if the SRT rail line is closed and is not replaced with an LRT along the same route), could become a shortcut route in another direction.

If one-seater lanes were built in these diagonal hydro corridors, and if a three card monty bus/bike/one-seater system were implemented on a number of Scarborough’s main streets intersecting these corridors, then the suburb’s transit, cycling, and driving might be significantly improved. Ideally, it will one day become easy to ride a bicycle or a velomobile from U of T Scarborough campus all the way to U of T in the heart of downtown T.
