There are five levels of automation in land vehicles:
Driver Assistance (DA) - hands or feet off.
Partial Automation (PA) - hands and feet off.
Conditional Automation - eyes off. The driver can take their eyes off the road in autonomous modes during defined scenarios (e.g. traffic jam pilot) but needs to take over control after system alerts.
High Automation - mind off. The vehicle can drive autonomously without human intervention except under extreme scenarios. In most cases, the driver can be 'mind-off', e.g. they can sleep during the journey and there is no take-over request for the driver. Most OEMs have claimed plans to launch Level 4 production cars in the early 2020s.
Fully Automated - driverless. The system can drive autonomously without any human intervention under any conditions. The end goal for robot shuttles.
Robot shuttles vs robotaxis
It is worth noting the difference between robot shuttles and robotaxis. Robotaxis are autonomous cars (level 4 or 5) intended to replace many private cars and taxis by being more affordable to own and use and available to more types of customer. Cheaper, widely available cars with reduced need for high focus and the use of hands and/or feet would make personal transport more accessible for disabled people, and a potential peace of mind for worried parents watching their teens drive off for the first time.
Robot shuttles, on the other hand, are box-shaped road vehicles designed for slow-speed, multi-purpose city use. It is expected that people will use them rather than buy them. Because robot shuttles are zero-emission, compact and multi-purpose, the possible future they present is one where there are no private vehicles in city centers: accessible, electric, fully automated transport would ease congestion and eliminate the need for private car ownership within cities. They are intended to help to solve the problems of road safety, congestion, expense, emissions, and lack of suitable vehicles.
Robot shuttles are already in action - 37 types in 15 countries as quoted by IDTechEx.
Baidu, China's answer to Google, is working with Chinese bus-maker King Long to build buses, called Apolong based on its Apollo design. In 2018, it made and deployed 100 of them in over 30 Chinese cities. The buses can seat 14 passengers, but there is no driver's seat or steering wheel. Apolong comes with level 4 autonomous driving capabilities, which do not require a driver within a specific geographic area, according to the National Highway Traffic Safety Administration (NHTSA). The company also announced updates to its self-driving platform, called Apollo.
Aurrigo is conducting many driverless pod trials. One such trial involved blind veterans in Brighton as part of an exercise to explore possible 'first and last mile' transport solutions. The company joined forces with Blind Veterans UK to develop a six-month programme of testing that started in April 2020. This was the first time Aurrigo has ever conducted an extended trial with veterans or people with a disability, and the results indicated an overall positive experience for participants, including reduced travel anxiety.
Smart Cities
The updates to cars may be expected, but what about the roads themselves? Smart Cities could mean roads that generate solar electricity, and even charge electric vehicles through the road surface, as well as interact with autonomous vehicles to direct traffic and present congestion.
A project for this concept currently underway is Toyota's 'Woven city' in Japan. The city will be designed with three different types of streets: one for self-driving vehicles, one for pedestrians using personal mobility devices like bikes, and one for pedestrians only. The rooftops of buildings will be covered in photovoltaic panels to generate solar power and hydrogen fuel cell power, and all around will be native vegetation grown using hydroponics: a method of growing plants without soil.
A fleet of Toyota's self-driving electric vehicles, called e-Palettes, will be used for transportation, deliveries, and mobile retail throughout the city.
From the roads to the skies
What vision of a sci-fi future is complete without flying cars? The concept of air taxis is not quite the flying cars of Back to the Future; in fact, air taxi services with vertical take-off and landing are not a new concept. Helicopters have been certified for civilian passenger transport since the late 1940s, but have always remained an expensive and niche form of transport. Recent advances in electric battery technology and electric motors, however, have facilitated the design of these aircraft with distributed electric propulsion (DEP) architectures that can alleviate a number of the issues which have prevented helicopter transport from becoming more widespread.
Air taxis could offer an advantage for cross-city trips in cities which lack existing transport infrastructure, or between cities which are relatively close by but have no direct transport links, for example between Cambridge and Oxford.
A leading air taxi manufacturer is Joby Aviation, who recently took over the hugely influential Uber Elevate programme. Joby are aiming for flight certification as early as 2023, with the launch of commercial operations from 2024.
