The 15-minute city: from vague memory to future reality (1/7)

Paris: La Ville du Quart d’Heure

Without changes to the transport system in which they operate, the advent of autonomous cars will not significantly improve the quality of life in our cities. This has been discussed in previous contributions. This change includes prioritizing investment in developing high-quality public transport and autonomous minibuses to cover the first and last mile.

However, this is not enough by itself. The need to reduce the distances we travel daily also applies to transporting raw materials and food around the world. This is the subject of a new series of blog posts, and probably the last.

Over the next few weeks I will be discussing the sustainability of the need for people and goods to travel long distances. In many cities, the corona pandemic has been a boost to this idea. Paris is used as an example. But what applies to Paris applies to every city.

When Anne Hidalgo took office as the newly elected mayor in 2016, her first actions were to close the motorway over the Seine quay and build kilometres of cycle paths. Initially, these actions were motivated by environmental concerns. Apparently, there was enough support for these plans to ensure her re-election in 2020. She had understood that measures to limit car traffic would not be enough. That is why she campaigned on the idea of “La Ville du Quart d’Heure”, the 15-minute city, also known as the “complete neighbourhood”. In essence, the idea is to provide citizens with almost all of their daily needs – employment, housing, amenities, schools, care and recreation – within a 15-minute walk or bike ride of their homes. The idea appealed. The idea of keeping people in their cars was replaced by the more sympathetic, empirical idea of making them redundant.

During pandemics, lockdowns prevent people from leaving their homes or travelling more than one kilometer. For the daily journey to work or school, the tele-works took their place, and the number of (temporary) “pistes á cycler” quickly increased. For many Parisians, the rediscovery of their own neighbourhood was a revelation. They looked up to the parks every day, the neighbourhood shops had more customers, commuters suddenly had much more time and, despite all the worries, the pandemic was in a revival of “village” coziness.

A revival, indeed, because until the 1960s, most of the inhabitants of the countries of Europe, the United States, Canada and Australia did not know that everything they needed on a daily basis was available within walking or cycling distance. It was against this backdrop that the idea of the 15-minute city gained ground in Paris.

We talk about a 15-minute city when neighbourhoods have the following characteristics

– a mix of housing for people of different ages and backgrounds – pedestrians and cyclists

– Pedestrians and cyclists, especially children, can safely use car-free streets.

– Shops within walking distance (up to 400 meters) for all daily needs

– The same goes for a medical center and a primary school.

– There are excellent public transport links;

– Parking is available on the outskirts of the neighbourhood.

– Several businesses and workshops are located in each neighbourhood.

– Neighbourhoods offer different types of meeting places, from parks to cafes and restaurants.

– There are many green and leafy streets in a neighbourhood.

– The population is large enough to support these facilities.

– Citizens have a degree of self-management.

Urban planners have rarely lost sight of these ideas. In many cities, the pandemic has made these vague memories accessible goals, even if they are far from reality.

In the next post, I will reflect on how the idea of the 15-minute city is moving from dream to reality.

When will robotaxi’s become commonplace? (8/8)

Autonomous shuttle bus in tourist hotspot Terhills (Genk, Belgium)

Until recently, optimists would say “in a few years.” Nobody believes that anymore, except for Egon Musk. The number of – so far small – incidents involving robot taxis is increasing to such an extent that the cities where these taxis operate on a modest scale, San Francisco in particular, want to take action.

Europe vs USA

In any case, it will take a long time before robotaxis are commonplace in Europe. There are two major differences between the US and Europe when it comes to transportation policy.

In the US, each state can individually determine when autonomous vehicles can hit the road. In Europe, on the other hand, a General Safety Regulation has been in force since June 2022 that applies to all countries. This states, among other things, that a driver must maintain control of the vehicle at all times. Strict conditions apply to vehicles without a driver: separate lanes, short routes on traffic-calmed parts of the public road and always with a ‘safety driver’ on board.

The second difference is that in the US 45% of all residents do not have public transport available. In Europe you can get almost anywhere by public transport, although the frequency is low in remote areas. Governments say they want to further increase accessibility by public transport, even if this is at the expense of car traffic. To this end, they want an integrated transport policy, a word that is virtually unknown in the US.

Integrated transport policy

In essence, integrated transport policy is the offering of a series of transport options that together result in (1) the most efficient, safe and convenient satisfaction of transport needs, (2) reduction of the need to travel over long distances (including via the ’15- minutes city’) and (3)  minimal adverse effects on the environment and the quality of life, especially in the large cities. In other words, transport is part of policy aimed at improving the quality of the living environment.

Integrated transport policy assesses the role of vehicle automation in terms of their contribution to these objectives. A distinction can be made between the automation of passenger cars (SAE level 1-3) and driverless vehicles (SEA level 4-5).

Automation of passenger cars

Systems such as automatic lane changes, monitoring distance and speed, and monitoring the behavior of other road users are seen as contributing to road safety. However, the driver always remains responsible and must therefore be able to take over steering at any time, even if the car does not emit a (disengagement) signal. Eyes on the road and hands on the wheel.

Driverless cars

‘Hail-riding’ will result in growth of traffic in cities because the number of car kilometers per user increases significantly, at the expense of walking, cycling, public transport and to a much lesser extent the use of private cars. Sofar, the number of people who switch from their own car to ‘hail-riding’ is minimal. The only way to reverse this trend is to impose heavy taxes on car kilometers in urban areas. On the other hand, the use of robot shuttles is beneficial in low-traffic areas and on routes from residential areas to a station. Shuttles are also an excellent way to reduce car use locally. For example, in the extensive Terhills resort in Genk, Belgium, where people leave their cars in the parking lot and transfer to autonomous shuttles that connect the various destinations on the site with high frequency.

A few months ago (April 2023), I read that Qbus in the Netherlands wants to experiment with 18-meter-long autonomous buses, for the time being accompanied by a ‘safety driver’. Routes on bus lanes outside the busiest parts of the city are being considered. Autonomous metros and trains have been running in various cities, including London, for years. It is this incremental approach that we will need in the coming years instead of dreaming about getting into an autonomous car, where a made bed awaits us and we wakes us rested 1000 kilometers away. Instead of overcrowded roads with moving beds, we are better off with a comfortable and well-functioning European network of fast (sleeper) trains on a more modern rail infrastructure and efficient and convenient pre- and post-transport.

Automated cars; an uncertain future (7/8)

For more than a decade, car manufacturers have been working on technology to take over driver’s actions. A Lot  of money has been invested in this short period and many optimistic expectations have been raised, but no large-scale implementation of the higher SAE levels resulted so far. Commercial services with robotaxi’s are scarce and still experimental.

The changing tide

Especially in the period 2015 – 2018, the CEOs of the companies involved cheered about the prospects; soon after, sentiment changed. In November 2018, Waymo CEO John Krafcik said that the spread of autonomous cars is still decades away and that driving under poor circumstances and in overcrowded cities will always require a human driver. Volkswagen’s CEO said fully self-driving cars “may never” hit public roads.

The companies involved are therefore increasingly concerned about the return on the $100 billion invested in the development of car automation until the end of 2021. The end of the development process is not yet in sight. Much has been achieved, but the last 20% of the journey to the fully autonomous car will require the most effort and much more investment. Current technology is difficult to perfect. “Creating self-driving robotaxi is harder than putting a man on the moon,” said Jim Farley, CEO of Ford, after terminating Argo, the joint venture with Volkswagen, after the company had invested $100 million in it.

The human brain can assess complex situations on the road much better than any machine. Artificial intelligence is much faster, but its accuracy and adaptability still leave much to be desired. Driverless cars struggle with unpredictability caused by children, pedestrians, cyclists, and other human-driven cars as well as with potholes, detours, worn markings, snow, rain, fog, darkness and so on. This is also the opinion of Gabriel Seiberth, CEO of the German computer company Accenture, and he advises the automotive industry to focus on what is possible. Carlo van de Weijer, director of Artificial Intelligence at TU Eindhoven, agrees: “There will not be a car that completely takes over all our tasks.”

Elon Musk, on the other hand, predicted that by 2020 all Tesla’s will have SEA level 5 thanks to the new Full Self Driving Chip. In 2023 we know that its performance is indeed impressive. Tesla may therefore be the first car to be accredited at SAE level 3. That is not yet SAE level 5. The question is whether Elon Musk minds that much!

The priorities of the automotive industry

For established automotive companies, the priority is to sell as many cars as possible and not to make a driver redundant. The main objective is therefore to achieve SAE levels 2 and possibly 3. The built-in functions such as automatic lane changing, keeping distance, and passing will contribute to the safe use of cars, if drivers learn to use them properly. Research shows that drivers are willing to pay an average of around $2,500 for these amenities. That is different from the $15,000 that the beta version of Tesla’s Full Self Driving system costs.

The automotive industry is in a phase of adjusting expectations, temporizing investments, downsizing involved business units, and looking for partnerships. GM and Honda are collaborating on battery development; BMW, Volkswagen and Daimler are in talks to share R&D efforts for autonomous vehicles; and Ford and VW have stopped developing an autonomous car and are working together on more realistic ambitions.

Safety issues at SAE level 3

But even with a focus on SAE level 3, the problems do not go away. The biggest safety problem may well lie at this level. Elon Musk has suggested for years that Tesla’s autopilot would allow drivers to read a book or watch a movie. All they must do is stay behind the wheel. They must be able to take control of the car if the automatic system indicates that it can no longer handle the situation. Studies in test environments show that in this case the reaction time of drivers is far too long to prevent disaster. An eye on the road and a hand on the wheel is still mandatory everywhere in the world, except in  few paces for cars accredited at SEA level 4 under specified conditions.

The assumption is that the operating system is so accurate that it indicates in time that it considers the situation too complex. But there are still many doubts as to whether these systems themselves are sufficiently capable of properly assessing the situation on the road at all times. Recent research from King’s College London showed that pedestrian detection systems are 20% more accurate when dealing with white adults than when dealing with children and 7.5% more accurate when dealing with white people compared to people with dark skin.

In the next post I will go into more detail about the legislation and what the future may bring.

First driverless taxis on the road 6/8

Since mid-2022, Cruise and Waymo have been allowed to offer a ride-hailing service without a safety driver in a quiet part of San Francisco from 11pm to 6am. The permit has now been extended to the entire city throughout the day. The company has 400 cars and Waymo 250. So far, it has not been an unqualified success.

A turbulent start

In a hilarious incident, an empty taxi was pulled over by police; it stopped properly, but kept going after a few seconds, leaving the officers wondering if they should give chase. The National Highway Traffic Safety Administration is investigating this incident, as well as several others involving Cruise taxis stalling at intersections, and the Fire Department reports 60 incidents involving autonomous taxis.

Pending further investigation, both companies are only allowed to operate half of their fleet. In addition to the fire department and public transport companies, trade unions are also opposed to the growth of autonomous taxis. California’s governor has rejected the objections, fearing that BigTech will swap the state for more car-friendly ones. It is expected that autonomous taxis will gradually enter all major US cities, at a rate just below that of Uber and Lyft.

Cruise has already hooked another big fish: In the not-too-distant future, the company will be allowed to operate autonomous taxis in parts of Dubai. 

The number of autonomous taxi services in the world can still be counted on one hand. Baidu has been offering ride-hailing services in Wuhan since December 2022, and robot taxis have been operating in parts of Shenzen since then.

Singapore was the first city in the world to have several autonomous taxis operating on a very small scale. These were developed by nuTonomy, an MIT spin-off, but the service is still in an experimental phase. Another company, Mobileye, also plans to start operating in Singapore this year. 

The same company announced in 2022 that it would launch a service in Germany in 2023 in partnership with car rental company Sixt 6, but nothing more has been heard. A survey by JD Power found that almost two-thirds of Germans do not trust ‘self-driving cars’. But that opinion could change quickly if safety is proven and the benefits become clear.

What is it like to drive a robotaxi?

Currently, the group of robotaxi users is still small, mainly because the range is limited in space and time. The first customers are early adopters who want to experience the ride. 

Curious readers: Here you can drive a Tesla equipped with the new beta 1.4 self-driving system, and here you can board a robotaxi in Shenzhen.

The robotaxis work by hailing: You use an app to say where you are and where you want to go, and the computer makes sure the nearest taxi picks you up. Meanwhile, you can adjust the temperature in the car and tune in to your favourite radio station.

Inside the car, passengers will find tablets with information about the journey. They remind passengers to close all doors and fasten their seatbelts. Passengers can communicate with remote support staff at the touch of a button. TV cameras allow passengers to watch. Passengers can end the journey at any time by pressing a button. If a passenger forgets to close the door, the vehicle will do it for them. 

The price of a ride in a robotaxi is just below the price of a ride with Uber or Lyft. The price level is strongly influenced by the current high purchase price of a robotaxi, which is about $175,000 more than a regular taxi. Research shows that people are willing to give up their own cars if robotaxis are available on demand and the rides cost significantly less than a regular taxi. But then the road is open for a huge increase in car journeys, CO2 emissions and the cannibalisation of public transport, which I previously called the horror scenario.

Roboshuttles

In some cities, such as Detroit, Austin, Stockholm, Tallinn and Berlin, as well as Amsterdam and Rotterdam, minibuses operate without a driver, but usually with a safety officer on board. They are small vehicles with a maximum speed of 25 km/h, which operate in the traffic lane or on traffic-calmed streets and follow a fixed route. They are usually part of pilot projects exploring the possibilities of this mode of transport as a means of pre- and post-transport.
