By far the biggest advantage that a large truck has over a small truck is that a large truck has lower labour costs, per unit of cargo transported. Self-driving technologies that reduce or eliminate labour costs may therefore lead to an increased use of smaller trucks.
This could be particularly likely to occur in areas that have rugged terrain, where labour costs tend to be especially high as a result of slower driving speeds and higher insurance costs.
Small vehicles are also better at handling rugged terrain than large vehicles are. They can make sharper turns, have better control on narrow lanes, can pass through narrower tunnels or overhangs, and can manage steeper inclines.
Indeed, the biggest beneficiaries of automation might be the smallest roads of all: mountain paths that can today only be used by very small vehicles or pack animals. Very small autonomous vehicles could revolutionize transport on such paths not only by eliminating the need to pay drivers’ wages and insurance, but also by gaining more space to carry cargo as a result of no longer needing space for the driver, the steering wheel, and spare tires. These vehicles could be used to facilitate shortcut routes that pass through rugged terrain, or to open up rugged terrain to increased economic activity.
The use of small autonomous vehicles in rugged terrain might also allow for the introduction of another new technology : roll-on, roll-off ropeways. These would be ropeways that small autonomous vehicles would drive on and off of, or clip on and off of, in order to be carried above natural barriers such as steep inclines, rivers, flash-flooded roads, or snowed-in high-altitude mountain paths.
They could be especially efficient at handling inclines, not only by allowing direct as-the-crow-flies routes to replace winding, hairpin roads, but also because ropeways operate as a pulley system wherein the weight of descending vehicles does much of the work — and often does all of the work — of lifting the weight of the ascending vehicles.
Here you can see a very primitive RoRo-Ropeway at work. Here, you can see a somewhat less primitive, though still limited, version built in a Volkswagon factory in Slovakia. If automation leads to a proliferation of small autonomous cars, working ant-like to transport goods in rugged terrain, then perhaps we will see systems like these increase and improve. Economically, it may be as close as we get to flying cars anytime soon.
Roads and railways are great, but they are not portable, scalable, or particularly well suited to ideally handling rugged terrain. You cannot easily disassemble a road or railway in order to move it from location to another. You cannot easily drive trucks or trains up and down steep hills, or across icy or snowy or flooded-out landscapes. You cannot widen a road or railway very much without facing sharp increases in expense. The wider you build them, the more likely they are to find a natural or man-made barrier in their way. The widest stretches of highway in the world rarely exceed 150 metres.
Ropeways, in contrast to roads or railways, are portable, are scalable, and are ideally capable of handling rugged terrain. You can fairly easily disassemble and transport them. You can scale them horizontally or vertically. Ropeway corridors could be made extremely wide without being blocked by natural barriers. So long as they are portable and temporary, wide ropeway corridors might also be able to avoid unduly bothering the owners of the private farmland they would inevitably need to cross above at times.
Their potential combination of portability and scale could make ropeway corridors useful for transporting bulk, time-dependent goods: for transporting crops at harvest time, or transporting cargo during the rainy season when roads are flooded out, or in snowy areas during the winter, or to help construct and access mines or dams.
There are a number of factors that could make ropeway corridors become common in the future:
cheaper intermodal transportation as a result of autonomous cargo transferring. Thus far, the costs associated with transferring cargo from one mode of transport to another have led trucks to account for an estimated 70% of all US cargo transport, despite trucks being generally much less efficient than railways or waterways. If loading, unloading, and handling cargo becomes automated, we might expect that railways, waterways, and perhaps even ropeways will become used more widely as a result
automating cargo-handling also means that ropeways would be able to add many more entrance and exit points than they have had in the past. Loading cargo on and off ropeways is especially labour-intensive, because the cargo arrives and departs at a slow trickle, each vehicle on the ropeway carrying much less than a truck or train. This has meant that ropeways have tended to move goods only from point A to point B, without many or any intermediate stations. Autonomous cargo-handling could change this, dramatically increasing the usefulness of the ropeway system
cargo tracking systems — ropeways are slow, which in the past created uncertainties for those waiting for the goods they are bringing. With today’s cheap GPS tracking systems and software that can estimate arrival times (and adjust those estimations when there are unexpected delays of one sort or another), these uncertainties are reduced
partially-autonomous maintenance: some of the technologies now being deployed or developed for maintaining vast electric grid systems should be applicable for ropeways as well. These include, for example, sensors and computer systems that monitor the entire length of the system in real-time, and drones that can be used as cameras to make inspections
in some cases passenger cable cars might be able to share the same ropeway as cargo systems – perhaps with passengers being transported during the daytime and cargo transported overnight. Ropeways might also benefit, therefore, from technologies that facilitate intermodal passenger transportation: for example car-sharing, ride-sharing,autonomous valet parking, and other technologies might make it easy for a passenger to drive to a cable-car’s entrance and then transfer seamlessly to in a different vehicle upon reaching the cable-car’s exit.
It’s true that pyramids have fallen out fashion in recent millennia. All of the pyramids that have been constructed in modern times are shorter than the Great Pyramid of Giza, which was built four and a half thousand years ago.
The two largest of these are the Memphis Pyramid (Memphis, Tennessee, that is), where the Grizzlies NBA team played from 2001-2004, but which has since been turned into a giant Bass Pro Sports Shop; and Las Vegas’ Luxor Hotel and Casino, the most vice-ridden pyramid this side of Pyongyang.
At 98 and 107 metres, the tips of these two American pyramids are both taller than the roof of Toronto’s Skydome (which, for purposes of comparison, is 86 metres tall). But both are still much shorter than Giza’s, which is 139 metres.
The next tallest modern pyramid, which finished construction in 2000 in Khazakstan’s built-from-scratch capital city Astana, is 77 metres tall. Other notable modern pyramids include California’s Walter Pyramid, a 5,000-seat sports arena on the campus of Long Beach State University that is 58 metres tall; the Pyramid of Kazan, the largest recreation facility in Russia at 30 metres tall; and museums like the Nima Sand Museum in Japan or the Louvre Pyramid.
Pyramids have three significant advantages over other buildings–but also a key flaw, which has outweighed these advantages.
The advantages of pyramids are that they are durable,climbable , and do not obstruct city skylines to the same extent that a rectangular or dome-shaped building of equivalent height would.
In spite of these advantages, pyramids have a flaw, which has relegated them to serving mainly as a home for the spookily intact remnants of once-great kings (like Tutankhamen, or Vince Carter). Their flaw is simple: most of their indoor space lacks good window access. Windows are sort of a deal-breaker for modern humans. This is why you do not see many pyramid-shaped residential condos, but instead only entertainment facilities or Bass Pro Shops.
You don’t need to be a brain surgeon to know that one thing pyramids and ziggurats could be good at is storing things. A ziggurat could be ideal for this: it could serve simultaneously as a storage facility (on the inside) anda public gardens (on the outside).
This assumes, however, that cities are actually in need of large new storage facilities. For post-industrial cities like Toronto, this may not be the case. If Toronto were to build a large ziggurat, what would be stored inside of it?
This is where the introduction of autonomous cars could, maybe, make things interesting.
Though we don’t know what the future of rush hour traffic jams or weekend traffic lulls will be, it is plausible that in the future there will at times be an excess capacity of cars in Toronto, numbering in the tens or even hundreds of thousands. Since autonomous cars will be able to drive themselves, this raises the question of where the best place for them to go at such times would be.
One possibility is to keep doing what we do now: leave cars parked all over the place. It is probable, I think, that this is what we will do — and that’s okay. Yet it is also likely that we will seek to do this less and less often, given that any space occupied by parked cars could be better used as a green space, commercial space, residential space, extra lane for driving, etc. Leaving autonomous cars parked all over the city would not seem to be sensible or necessary.
Another option is to build more underground parking lots. Today less than one percent of the city’s parked cars are in underground lots; it would seem only natural that this number will increase as a result of autonomous cars. Such cars would not mind squeezing themselves down narrowly winding ramps to reach cramped parking spots in the bowels of the earth.
Still, building underground lots is not cheap. As you dig further and further down, construction prices tend to rise sharply, as a result of the need to keep out groundwater, prevent surrounding buildings from being destabilized, and lift earth high and higher to get it out of the hole you’ve dug.
But What About That Ziggurat?
Thus, we are left with the alternative of having excess autonomous cars drive themselves into vertical parking lots. In some cases, having these buildings be ziggurats could work best, given that they are durable, do not block skylines much, and can double as a Hanging Gardens.
The best place to put a ziggurat in Toronto could be the Exhibition. The Exhibition has enough room for a large building, and would make the ziggurat a part of the Toronto skyline. From the Exhibition Ziggurat’s Hanging Gardens, there would be a clear view of the lake, the revitalized Ontario Place island, and CFL or MLS games being played at BMO field. (Also, concerts being played at Molson Amphitheatre would be audible). It would be accessible by car (as it would itself be a gigantic parking lot) as well as by GO Train from Union.
As a massive parking lot for shareable autonomous cars, the Exhibition Ziggurat could help make the removal of the downtown Gardiner a workable possibility, by allowing commuters to drop off their cars at Exhibition Station in order to transfer to the train or bus. Similarly, at times when Union Station is overcrowded, the Ziggurat could help allow commuters to get off the train at Exhibition Station in order to switch to an autonomous car.
Given that there are several marinas next to the Exhibition, it could perhaps become possible even that cars could go to and from the ziggurat by being carried by autonomous boats on Lake Ontario. This way, cars could at certain times be picked up or dropped off at various points along the city’s waterfront, using the lake to avoid downtown traffic. In theory at least, excess cars could even be delivered to St Catharines via boat, using the lake as a shortcut to reduce the distance between Toronto and Niagara from 130 km (via the QEW) to just 50 km.
If you want to get even crazier, you could do as the Egyptians did and built not one pyramid, but several. You could turn Downsview Park into a post-modern Necropolis, full of hanging gardens and autonomous car parking spaces, with easy access to the University subway line, the 401, the Allen, and Sheppard.
If Egypt is any indication, such an investment could at least pay off in the the very, very long run.
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.
