Prepare For Gridlock If Future For Autonomous Vehicles Is Plentiful Cheap Journeys

https://www.forbes.com/sites/carlton...h=3810bee91434

.....

- In the future, we will be able to travel where we want, when we want at low cost because we will no longer own cars and nor will we have to pay the high costs of human drivers. --- It is a fundamental principle of economics that when the price of a good decreases, the quantity demanded increases. In other words, make something cheap, and people will buy lots of it. Make motoring even cheaper than it is today, and people will consume even more of it. In that scenario, the future for AVs is gridlock.

The hype, high hopes and sobering reality of the future of car travel

https://www.abc.net.au/news/2021-02-...aring/13178910

- Users will end up paying for the inefficiencies that already exist in the industry (such as the amount of time cabs sit empty), as well as the cost of remote operators who would be needed to step in in the event of a malfunction. Then there's the cost of infrastructure ensuring roads are clear and painted so they can be recognised by sensors. — While the computing systems in cars today have between 80-100 million lines of computer code it's expected driverless cars would need at least double that. The challenge here, of course, is equipping the vehicles with enough computing capacity to be able to churn through these gigabytes and gigabytes of data that are being produced. More computing capacity means more weight. The more computers you squeeze on board these vehicles, the more fuel inefficient you actually make the vehicle.

On-demand driverless pods mooted for £2bn Cambridgeshire Autonomous Metro

https://www.newcivilengineer.com/lat...ro-18-03-2021/

Quote:
.....

- Concept designs for the Cambridgeshire Autonomous Metro (CAM) have been revealed as part of the ongoing design process. The designs have been drawn up by three teams shortlisted to move the project forward. Designs include the vehicle, the infrastructure, and how the system would operate. While the design challenge was not intended to find an ultimate delivery solution for CAM, aspects of the designs and innovations demonstrated could be adopted as part of the next business case phase which begins in April. --- Dromos Technologies proposal includes 84 stops across a network that runs 24/7, 365 days a year. Passengers travel non-stop in their own driverless vehicle, without having to share with other passengers. The Dromos vehicles arrive in under two minutes to a passenger’s location when summoned via a mobile phone or electronic kiosk placed along the CAM network.

Opinion: A way to get transit on Beltline

https://www.ajc.com/opinion/opinion-...K4I5DDD3ASSEQ/

Quote:
.....

- Autonomous shuttles can provide efficient, electric, and inexpensive mass transportation for a fraction of light rail’s cost. — The invention and subsequent rapid development of autonomous transit have brought about a more diverse set of transportation investment options for consideration. Autonomous, mass transit shuttles operating on geo-fenced closed loops are consistent, reliable, and, more importantly, cost-effective.

- Light rail on the Beltline will cost upwards of $570 million and be complete sometime around 2045, assuming funding gaps are closed. Autonomous shuttles, on the other hand, can provide efficient, electric, and inexpensive mass transportation on the entire Beltline for a fraction of the cost. Each electric autonomous shuttle costs approximately $500,000. To cover the whole Beltline with constantly circulating autonomous shuttles, you’d need nearly 200 shuttles.

Self-Driving Robocar Will Be Your Personal Assistant, Doesn't Need a Steering Wheel

https://www.autoevolution.com/news/s...el-167781.html

Quote:
.....

- Baidu, the Chinese tech giant, has recently revealed the robocar, a vehicle with no steering wheel and automatic gull-wing doors that is said to be capable of level 5 autonomy. In addition to the robocar, the company launched Luobo Kuaipao, an autonomous driving service platform aimed at boosting the commercialization of its autonomous driving tech.

Can ‘Personal Rapid Transit’ Really Replace Buses and Trains?

https://usa.streetsblog.org/2023/06/...ses-and-trains

Quote:
.....

- In April, transportation leaders in America's 10th largest city announced that they had greenlit the first leg of a new "personal rapid transit" (or PRT) system, with an initial route to run between the Diridon regional transit hub and San Jose's international airport. The project beat out traditional buses and trains, neither of which serve the airport now, and oft-blogged-about technologies like Virgin Hyperloop and Elon Musk's Boring Company tunnels, despite the fact that PRT systems, to date, only exist in a handful of airports, a futuristic Dubai neighorhood, and one small town in West Virginia. --- Moreover the city says that the estimated $500-million project is only the beginning, and the system, as it expands, will eventually serve as a national model for "a new approach to transit that can be designed and built faster and at lower cost, and offers a better rider experience than traditional transit systems."

The title says it all. Individual vehicles replacing buses and even trains. Is that ever an efficient way to move large numbers of people? We start talking about elevated or underground infrastructure and large stations to accommodate individual vehicles often carrying only one person. What happens if this is too successful and the stations become overwhelmed? Not cheap to expand, and potential line-ups waiting for vehicles. Like every form of public transport, whether publicly or privately operated, costs will limit the number of vehicles available especially during peak travel hours.

Uber was supposed to help traffic. It didn’t. Robotaxis will be even worse

https://www.sfchronicle.com/opinion/...c-18362647.php

Quote:
.....

- The real threat from robotaxis is the underlying technology. Once these cars inevitably learn to get around the traffic cones and gain the public’s trust, their convenience could seduce us into vastly overusing our cars. The result? An artificial-intelligence-powered nightmare of traffic, technically perfect but awful for our cities. Why do we believe this? Because it has already come to pass with ride-sharing. --- The futuristic allure of autonomy — and the enormous profits it could generate for its creators — will be hard for governments and the public to resist. But we cannot let a shiny new piece of technology drive us into an epic traffic jam of our own making.

- The best way to make urban mobility accessible, efficient and green is not about new technologies — neither self-driving cars nor electric ones — but old ones. Buses, subways, bikes and our own two feet are cleaner, cheaper and more efficient than anything Silicon Valley has dreamt up. What’s the Cadillac of reducing our dependence on Cadillacs? The good old-fashioned bus. --- This is not to say self-driving technology has no role in the future, just a different (and perhaps a bit less lucrative) one than GM-backed Cruise and Alphabet-backed Waymo seem to be currently focused on. Autonomous technology could, for example, allow cities to offer more buses, shuttles and other forms of public transit around the clock.

- To get new technologies right, our cities might follow the example of Singapore. Thanks to its Smart Nation program, the Asian city is now at the forefront of experimentation with autonomy. Yet, like San Francisco, it has experienced hiccups with its self-driving car pilot programs; young people have taken to confusing the vehicles by throwing balls or, more boldly, getting in front of them and dancing. The first reaction of the government, unamused, was to mull a law banning the harassment of self-driving cars. --- However, unlike San Francisco, Singapore has little to worry about in the long run because it already has robust systems to control traffic — a highly efficient mass transit network and a system of Electronic Road Pricing that dynamically taxes cars to prevent congestion.
