The Speed of CPT (and Chickadees)

The other day I wrote about how Toronto’s streetcars were like shooting chickadees with cannonballs.  In terms of speed, the streetcars were designed to operate at speeds far in excess of what was possible in an urban environment.

So how does CPT stack up on our Cannonball Index (that doesn’t exist, by the way, but wouldn’t it be great if it did)? Pretty well, in fact.

Cable-Propelled Transit maxes out at around 40 km/hr and most are built with a maximum speed of around 27 – 35 km/hr. Doesn’t sound too impressive, does it?  Remember, though, these vehicles actually travel at that speed. None of this built to go 100 but actually goes 10 nonsense.

Of course we have to factor in the time required for the vehicle to stop and allow passengers to alight and board but that time is offset by three major factors:

First, terminal time.  Because CPT is almost always fully automated, terminal time (the time a vehicle idles at its two terminal stations) is statistically irrelevant.

Second, drivers’ breaks.  Again, because CPT is typically fully automated with driverless vehicles no time and speed loss occurs due to bathroom breaks.

Third, crawl speed.  In the case of aerial-supported Gondola systems, vehicles don’t stop at stations. Instead, they are slowed down to what is known as “crawl speed” or “creep speed”.  Vehicles move through the stations at a speed of less than a meter per second allowing passengers to safely board and alight.  For those with accessibility issues, the vehicles can be stopped entirely for safe loading. Crawl speed doesn’t have a dramatic impact on overall average speed, but it does increase it somewhat.

So next time you’re riding a streetcar in Toronto . . . please, think of the chickadees.

Plz kanz yous think of me?

Please, think of me?

LT1M Wait Times

Less-Than-One-Minute (LT1M) wait times should be the goal of every transit planner because it is a principle that focuses on the user rather than the operator.

What the user wants is simple:  to be able to travel whenever they want regardless of schedule.

Imagine . . .

. . . if your front door only opened for 30 seconds every 15 minutes . . .

. . . or what if the opportunity to start your car’s engine only occurred once in every 10 minutes but always at a different point during those ten minutes . . .

. . . or how about never having a pair of shoes when you desperately need go outside only to find 4 pairs lined up in a row when you decide to stay indoors.

You’d lose your mind, you know you would.  And yet, that’s what we live with given our current transit systems.  It’s a testament to the resiliency of humanity that we still really want to make public transit work, but resiliency only lasts so long.

That’s why public transit so often loses the battle to bikes, feet and cars.  People like the convenience of being able to depart at their convenience not the convenience of their scheduled service provider.

Schedule service, when you think about it, is not really service at all . . . except for those administering and operating it.

Demand LT1M.

Time Is A Non-Renewable Resource…

. . . and that’s true for each and every one of us. Sure, it’s possible that time is infinite in the macro scale, but for our individual selves that’s just not so (despite what Aubrey de Grey might have us believe).

Time is the most precious thing we have and yet our current transit systems refuse to acknowledge the fact: Excruciatingly long wait times; constant delays; inconsistent schedules; stop after stop after stop; and travel speeds that make walking a competitive option.

Why don’t we at least consider a transit alternative that doesn’t steal our lives from us a few minutes at a time?

We need transit that provides the following (at minimum):

LT1M wait times; frequent, reliable service; no schedules; round-the-clock availability; travel speeds above 20 km/hr.

I’m not about to say that Cable-Propelled Transit would ensure those things.  Instead, I’m asking us to consider the possibility that it might.

(Incidentally, for those who don’t know who Aubrey de Grey is, he’s a researcher convinced that immortality is within our grasps.  Clearly, he’s a little bit controversial but I’m rooting for him because if he’s right, then waiting for a Toronto streetcar becomes a viable option.)

Medellin MetroCable

The MetroCable in Medellin, Columbia is a fascinating example of Cable-Propelled Transit. It is one of the most important CPT installations in the world, particularly because it is fully integrated into the transit system. I use the term full integration to describe cable systems that allow for seamless movement between different modes of public transit without need of additional fares (a quality sorely lacking in the Portland Aerial Tram and Roosevelt Island Tram).

The MetroCable has been so successful, it has spawned a second line and plans are underway for a third.  This youtube video should get you up to speed on it:

Statistically Speaking…

. . . the chance of experiencing a fatality or injury while riding a cable system at a ski hill is lower than the while skiing itself. Enjoy the slopes!

Cables As Ferries?

One great advantage of ferry technology is that it can carry not only people, but cars too.  The great problem with ferries, however, is the time and money involved in using them.

Look at the Washington State Ferry Service, for example.  Here’s a ridiculously expensive transportation option that offers the convenience of required reservations and wait times of up to 60 minutes upon arrival at the terminal.  Even walk-on passengers are told to be there a minimum of 15 minutes prior to boarding.

Could Cable-Propelled Transit handle that job?  It’s been shown to cross water, but can it carry cars?

Check this out:

In Bratislava, Slovakia Doppelmayr has outfitted a Volkswagen factory with a CPT system capable of moving cars.

To do this for a large scale ferry service would be complicated, no doubt, but what the video above demonstrates is that with a little ingenuity and creativity, Cable is capable of a whole lot of things.
