Can ‘Private Fast Transit’ Actually Substitute Buses and Trains? — Streetsblog USA


Think about a solar-powered transit choice that is cheaper to construct than a prepare, cheaper to function than a bus, as handy as a cab, as non-public as private automotive, and as protected as a sophisticated AV — all working on a devoted path that leaves pedestrians, cyclists, and different highway customers to maneuver about unbothered. And it solely prices about $6 a journey.

If that sounds to good to be true, nicely — it could be. However metropolis officers in San Jose are apparently believers.

In April, transportation leaders in America’s tenth largest metropolis introduced that that they had greenlit the primary leg of a brand new “private fast transit” (or PRT) system, with an preliminary path to run between the Diridon regional transit hub and San Jose’s worldwide airport. The mission beat out conventional buses and trains, neither of which serve the airport now, and oft-blogged-about applied sciences like Virgin Hyperloop and Elon Musk’s Boring Firm tunnels, even though PRT techniques, so far, solely exist in a handful of airports, a futuristic Dubai neighorhood, and one small city in West Virginia.

Furthermore the town says that the estimated $500-million mission is barely the start, and the system, because it expands, will finally function a nationwide mannequin for “a brand new strategy to transit that may be designed and constructed quicker and at decrease value, and provides a greater rider expertise than conventional transit techniques.”

The initiative — at the least if it will possibly cross a battery of environmental, engineering and monetary critiques — will likely be operated by Bay space start-up Glydways, whose autos have been variously known as “robotic shuttles,” “pod automobiles,” and one thing out of the sci-fi dystopia “Minority Report.”

For his or her half, the corporate calls them “Glydcars,” they usually’re autonomously pushed and dispatched on-demand, operating at a max of about 31 miles per hour with out stopping at stations, and even at intersections. That is doable as a result of the robovehicles solely run on devoted roads about 5 ft extensive — roughly the width of a NACTO-standard bike lane — which might be configured to change nimbly between ground-level, elevated, and even subterranean paths at what the corporate claims will likely be a fraction of the worth of the comparable infrastructure required to deal with a heavy bus or prepare. And after they’ve accomplished their journeys, they’re going to relaxation in any variety of off-road disembarkation “bays” all through the town, which double as stops and remove the necessity for enormous depots.

Put all of it collectively, and Glydways CEO Mark Seeger, says the Glydcar is considered one of humanity’s finest instruments to combat automotive dependency — even when his merchandise look, at first look, an entire lot like a automotive, albeit a small one on a devoted highway.

“The elemental thesis right here is that there are too many automobiles on the highway, and the highway can not deal with it,” Seeger informed Streetsblog. “And for those who throw a few buses in there, it simply will get worse, as a result of they’re snarled in visitors congestion. … You’ve actually bought to consider the human ingredient right here, which is not nearly, ‘Let’s construct extra trains or bus lanes.’ Let’s truly remedy the issue of getting you to work, of getting me to housing that I can afford, and let’s do it for as many individuals as doable — and likewise, let’s not choke our planet, with local weather gases which might be inflicting a worsening disaster.”

Earlier than we unpack the objections sustainable transportation advocates might need with Seeger’s perspective — and there are a lot of — it is necessary to acknowledge that the issues he is making an attempt to resolve are very actual. There are far too many automobiles on the highway in the USA — a whopping 76 % of People drive alone to work — and mass transit companies have struggled to get residents to cease driving them and swap to shared modes. And even when different nations have executed much better, solely about 200 cities on Earth have constructed the type of fast, electrified metro techniques that Seeger argues are key to not simply getting folks to skip driving, however to provide them the type of handy and engaging mobility choice they’re going to truly wish to journey.

Advocates would possibly say, after all, that transit companies’ struggles with low ridership, failing fareboxes, and shoddy service are all issues that may be cured by strong subsidies — to not point out unsnarling buses from visitors by giving them their very own devoted lane and sign precedence.

However Seeger argues that at the least to some extent, these issues are inherent to mass modes. He maintains that even a world-class subway depends on a “paradigm of aggregation” whereby companies run huge autos to huge stations on mounted schedules no matter whether or not there’s sufficient folks to fill them, inflicting prices per passenger per mile to balloon to unsustainable ranges the moment the frenzy hour ends. He says that is a recipe for insolvency — and for high-quality transit to by no means be inbuilt any however the densest and richest locations on earth.

Furthermore, Seeger factors out that even when the prepare is operating at peak effectivity, folks do not significantly like being packed asses to elbows with strangers, or ready just a few additional minutes for a bus that may not come on time, or supply them a nice journey.

“The entire challenge with a bus line or a prepare line is that it’s underutilized,” he provides. “The Bay Space Fast Transit System is an financial demise spiral as a result of folks do not wish to use it as a result of the expertise is horrible. I imply, frankly, it’s terrible — folks get murdered on it and different nasty issues occur. However even apart from the adversarial occasions, it is simply not a very good expertise. Individuals would quite sit in visitors than take this method that’s already there. … And so we’re attempt to flip that on its head [with Glydways]; we’re making an attempt to supply a greater expertise.”

In fact, many transit advocates will query the notion that folks would actually choose a pod automotive expertise to a high-quality, clear, murder-free mass choice — particularly if driving non-public cars had been much less closely sponsored than it’s now. And a few additionally doubt that corporations like Glydways can truly present what they declare with out precisely the identical type of subsidy.

“A minimum of at first blush, my impression is that this looks like a system that is going to have all the identical prices you’d get from making a bus lane, however it’s going offer you much less capability, as a result of you’ve smaller autos,” stated Chris Van Eyken, director of analysis and coverage for the nonprofit Transit Middle. “I’d encourage warning right here.”

Regardless of their comparatively miniature dimension, Van Eyken questions whether or not Glydways’ lanes might actually be constructed for all that a lot lower than a typical bus fast transit line, given the universe of sentimental prices like permits and consultants that make up a lot of a typical BRT funds.

These prices might swell much more if Glydways makes good on its promise that “pedestrians won’t ever encounter Glydcars, and Glydcars won’t ever must cease and anticipate pedestrians to cross” with out ever encountering a signalized intersection — until walkers are outright restricted from crossing in locations the place paths cannot be elevated or tunneled underground. And that is to not point out the all-too-familiar political challenges concerned in constructing a bikeway, which, once more, is just about equivalent in dimension to a Glydway — or the a long time it will possibly take to combat these battles. (Seeger, who notes that he grew up in Holland, insists that “Bikes are crucial to me … and we cannot take away pedestrian lanes both.”)

Van Eyken additionally questions the corporate’s estimate that it might carry 10,000 folks per hour and probably transport extra folks than a traditional prepare — one thing Streetsblog SF additionally questioned in 2021 — particularly given {that a} household, say, shoving baggage right into a tiny pod on their option to the airport would possibly want a bit extra time to board. By design, a Glydways automobile can carry solely 4 folks, or much less if a kind of passengers is in a wheelchair, or carting a motorcycle, or hauling a load of groceries, and Van Eyken suspects they’d have load in quickly to maintain the Glydcars operating.

“PRT must run at unbelievable frequencies to make sure no ready,” he stated. “I imply, it’d most likely must have multiple automobile coming each minute. … I believe it is both going to serve a low quantity of individuals, to the purpose whether or not you wonder if it is price it, or it may be in excessive demand and be continually backed up — after which you are going to be begging for a bigger automobile.”

Seeger insists all these questions will likely be answered when the following technology of PRT is up and operating — and that advocates should not deal with earlier examples of the know-how, which did not have the type of superior AI that Glydways will depend on and solely lately matured.

“On the finish of the day, we’re about fairness of alternative, the entire goal of guideways, or PRT generally, is to create a scalable answer that may go from 4 % of cities on earth to hopefully just a few extra,” added Seeger. “And we consider that as fairness of alternative, by way of higher entry to mobility — and one {that a} bus or a prepare merely, technically and economically, can not present.” 

Advocates like Van Eyken object to that assertion – and query whether or not PRT is transit in any respect.

“It appears to be in a grey space the place it is actually near being a private automobile, however it lacks the pliability of a private automobile,” he stated. “If somebody desires that [personal vehicle] expertise, why would not they simply take a cab? … It is an untested idea, and I would be cautious of seeing my very own cityinvesting cash on this.”
