On Politics and the Weather…and Bike Lanes, in Toronto

I tend to agree with those who say that the ideal city would have both right-of-way transit lines and separated bike lanes on every major street. But I also recognize that this is not politically viable. Too many suburban voters are against it. Urbanites have enough clout to get bike lanes or transit, but not necessarily both.

For this reason, I think it would be best to advocate for transit only, leaving the issue of bike lanes to the side until the transit fight is won. Bike lanes are great too of course, but not nearly as useful as transit can be.

However, I also recognize that even this is not politically viable. There are too many bike enthusiasts who will not delay their push for better bike lanes. For these bike enthusiasts and transit advocates to present a unified front in their negotiations with suburbanites, they must first reach a compromise among themselves.

The compromise could be this: a hybrid transit/bike lane, which changes functions depending on the weather.

It would work something like as follows. On days when the weather is expected to stay within a range of, say, 0-30 degrees celcius, and not rain too much, cyclists will get to have a separated bike lane that is so wide that it will actually have two bike lanes within it: a passing lane and a slower lane. On these days, Toronto would become ideally the most bike-friendly city in North America.

However on days when the weather is expected to be too cold, hot, or rainy, bicylists will not be allowed to bike on major roads at all. Instead, the bike lanes would be used as a right-of-way bus lane.

Of course, there would be winners and losers in this plan, as in any political solution. The losers would be ultraenthusiastic cyclists, the people who love to brag about how they bike to work even in January.

The winners would be everybody else.

Because 12 is a Magic Number (On Numerology and Public Transit)

The number 12 has played a key role in human culture, showing up in places as diverse as the hours of the day, the tribes of Israel, the disciples of Christ, the jury of your peers, the major gods of Olympus, the inches in a foot, the Chinese Zodiac, the Latin Zodiac, or the egg-carton.

One reason for this is that 12 is divisible in three different ways: by 12 and 1, by 6 and 2, and by 4 and 3. Not until 18 (another significant number, in both Hinduism and Judaism) is a number again divisible in three ways. This is also the root of 13’s bad luck: it’s a prime number, divisible only by itself and one. 13 throws off 12’s groove.

Numerology and Public Transit? 

As in the case of the clock, calendar, and egg-carton, 12’s divisibility could perhaps be put to practical use in public transit.

Imagine for a moment that a road were to have three different bus lanes in each direction. In one of the directions, busses on one of the lanes would make stops every 200 metres, on another lane every 400 metres, and on the third lane every 1200 metres.  In the other direction, busses on one lane would make stops every 300 metres, on the second lane every 600 metres, and on the third lane every 2400.

The result of this would be that busses on all six bus lanes would arrive at the same place every 2400 metres. In addition, busses on the 200 metre and 400 metre lanes would arrive at the same place every 400 metres, and busses on the 200,300, and 600 metre lanes would all arrive at the same place every 600 metres. Five of the six lanes — the 200, 300, 400, 600, and 1200 — would all arrive at the same place every 1200 metres. Lots of opportunities for passengers to transfer easily from one lane to another might therefore be created by such a transit system.  Ideally, this would make the system both efficient and useful.

Of course, you’ve probably already spotted the problem with this plan: roads aren’t wide enough for six transit lanes!

In order to have a transit-by-the-dozen plan like this, you would need either narrower vehicles or wider roads.

In the case of wider roads, the solution is obvious: use highways. The challenge then, however, would be how to get the passengers to and from those highways. This may not be viable today — or at least, not politically viable — but it could perhaps become so with the advent of autonomous or semi-autonomous cars.  Autonomous vehicles could take passengers to and from transit stops located in or adjacent to the highways.

The same might be said of narrower vehicles. Narrow, one-seater autonomous or semi-autonomous cars might allow main streets to create six narrow lanes — three in each direction — to be used for a transit system. Not only would the vehicles themselves be narrow, but they may also require less space between lanes.

But, if anywhere, it is probably on highways, not ordinary roads, where such a plan might actually have potential. Highways are so wide that, rather than have six transit lanes in total, it could be possible to have twelve: a 200, 300, 400, 600, 1200, and 2400 in each direction.  You could  even name the lanes after the Zodiac.  You could then give a tourist directions like “take the Taurus for three stops, then swich to the Gemini.”

Alternatively, you could use only one lane in each direction, but still have different busses using the lanes stop 200,300, 400, 600, 1200, or 2400 metres apart. This would make the system possible on normal roads, with normal sized vehicles, rather than only on wide highways or with narrow autonomous cars.

This is all enormously speculative of course. I don’t expect to see it happen, and am not sure it would even be desirable.

I guess we’ll have to consult an astrologer to find out.

A Bazaar Alternative to The Scarborough Subway

If the transportation of the future is to be autonomous cars — or even just semi-autonomous cars — then it makes sense to build transit bazaars: locations that your car could drop you off at, where you could then find a carpool, minibus, bus, or train to take you on to your final destination. As in any good market, a transit bazaar will work best when it has a lot of “liquidity”. In other words, when it is both very large and easily accessible.

In Toronto, the obvious place to put such a transit bazaar is by the intersection of the 401 and DVP. This intersection, of Toronto’s main north-south and east-west expressways, is enormous, and it is also only one kilometre away from the Sheppard Subway’s Don Mills Station.

DVP-401 Intersection

With that in mind, here is a 4-step proposal for an alternative to the City of Toronto’s current plan to extend the Bloor-Danforth subway to Scarborough Town Centre:

1. Build a major Transit Bazaar immediately northeast of the intersection (the other areas surrounding the intersection are residential neighbourhoods); extend the Sheppard Subway tunnel 1 km to reach a new subway station under the bazaar.

2. Build vertical (semi-)autonomous parking lots in the “urban archipelago” lands that are located within and immediately surrounding the intersection’s highway cloverleafs. These parking lots will be able to serve far more cars than any traditional vertical parking lot could: with no humans in them, they will be able to fill nearly every cubic metre of their volume with cars.

3. Extend the Sheppard subway 6.3 km to Scarborough Town Centre — but, rather than in a tunnel, extend it as a one-stop surface railway that would travel along two of the middle lanes of the 401 Highway.  This is  in lieu of, not in addition to, the current one-stop, 6.2 km subway extension plan that is set to go from Kennedy Subway Station to Scarborough Town Centre.

4. Build a 12 km cable-car directly above the Highway 401:

The cable-car’s 7 stops, from west to east, will be: the DVP’s Transit Bazaar (with a new subway station beneath it), Warden (where the north-south Warden hydro corridor and the northwest-southeast Shropshire corridor meet), Kennedy (which will be halfway between the Agincourt GO Station and the current SRT/potential future LRT stations of Ellesmere and Midland), Scarborough Town Centre (the halfway point of the cable-car line), Centennial College, Rouge Valley Hospital, and U of T Scarborough.

The cable-car will increase the transit capacity of the 401 (a place where it won’t be an eyesore, as it might be if you were to put it above an ordinary street), and will also help connect people to the Transit Bazaar and the Scarborough Town Centre “Surface Subway” station.

Why This Wouldn’t Have Made Sense in the Past, But Might Now 

In the past, this would have made little sense, as a result of the “first-mile/last-mile” problem. People do not want to live or work next to superhighways like they do next to subways, so most people using the train or cable-car would not be within walking distance of it.

In addition, building a decent train station in the middle of a highway is expensive, so it would not be affordable to have many stations—as a result, very few people would be within walking distance of it. (Cable-cars don’t have this second problem, since their stations wouldn’t need to be in the middle of the highway. This is one reason why the combination of the highway surface rail and highway cable-car could work well). As a result, such trains or cable-cars weren’t a good idea.

Toronto does, of course, have a few kilometres of surface rail in the middle of highways, namely on the Allen Expressway. However the Allen is much narrower than the 401 is, and runs in a shallow trench that made building subway stations like Glencairn and Lawrence West not too expensive. But even these stations have not been among the best at fostering urban development in the neighbourhoods around them.

Going forward, in contrast, while subways are obviously likely to remain worthwhile for a  long time yet — downtown Toronto should definitely build a new subway line, for example — surface rail’s “first-mile/last-mile” challenge is likely to be overcome, or at least greatly reduced, by technologies such as parking apps, transit apps, ride-sharing, car-sharing, semi-autonomous cars, and eventually (and especially) fully autonomous cars. As such, building a train that needs no tunnelling, and a cable-car that needs no road space, could be a great move.

Certainly it would be better than the 6.2 km one-stop tunnel to Scarborough Town Centre that is the city’s current plan (voted for by 27 of Toronto’s 43 city councillors). Almost anything would be better than that.

The Witching Hour: How To Fix Traffic in 3 Easy Steps, Without Resorting To Autonomous Cars


1. Allow autonomous cars during “the Witching Hour”: from 4 am-5 am. They can drive slowly in order to be safe and quiet; say, at no more than 10 km per hour when in residential neighbourhoods. Even at these slow speeds, this will allow car-sharing  cars to be delivered to peoples’ homes for use the following morning. (In fact, the cars themselves do not even necessarily need to have an autonomous capability. They could instead just hitch a ride on top of slow-moving road roombas). In the case of electric cars, this will also allow them to drive themselves to and from battery-charing stations at night, when electricity tends to be cheap and road-traffic sparse.

2. On main streets, have both an express LRT lane — with stops very far apart from one another — and a non-express bus lane. On narrower streets, have the non-express busses share a lane with regular car traffic.

3. Next to many of the LRT stops, as well as next to train stations, construct “take a car, leave a car” vertical parking lots. These will be “valet” lots: you drive a car-sharing car to the lot’s entrance, then get out of the car and have it drive itself (or be carried by a road roomba) into the lot to park. This will not only save drivers time in parking, but will also allow the lot to hold far more cars than any traditional vertical parking lot could, since without humans it can have much shorter ceilings, more tightly winding ramps to get cars up or down floors, and many more parking spots per floor. It will allow easy pick-up or drop-off of car-sharing cars. Along with the Witching Hour, this will overcome the “first mile-last mile” problems that otherwise tend to limit public transit’s effectiveness and appeal.

…So, there you have it. Three easy steps! With the Witching Hour, and car-sharing, and vertical parking lots, we can finally help to get rid of our cities’ spooky traffic problems.
