How smarter cars and digital cities are about to change the way we drive

Digital communications tech is coming to a car near you

Travel and settlement has always been fuelled by the latest tech known to man. Steam power, coal, electricity and the humble combustion engine have propelled humans around cities and across the seas.

But forget fossil fuels; now it's data that's helping shape the next generation of smart cars and cities where 'intelligent mobility' is the next big thing for drivers.

Over half of all humans – 3.5 billion of us – live in cities. By 2050, that will double, which means we've got to find a way of making our cities work much more efficiently – and that means transport.

Intelligent mobility

Intelligent mobility describes any technology that increases transport network capacity while also reducing accidents and pollution. It's largely about collaboration, about creating both cars and cities that can communicate with each other, and react accordingly.

It starts with a car dashboard that knows about upcoming traffic jams in advance and automatically re-plots a route to avoid it, perhaps taking into account congestion zone charges.

And it reaches its zenith when cars automatically change speed to avoid each other, with the idea of 'platooning' when the lead car at traffic lights literally sets the exact pace of all cars behind – all networked and communicating in real-time – in an effort to get more cars through junctions as quickly as possible.

Humans losing control of their own vehicles is a distant memory in the dreams of transport planners, and while no world city is anywhere near that point, some are distinctly 'smarter' than others.


Singapore: the smart government

An island megalopolis of five million people, wealthy Singapore is one of the world's greatest centres of capitalism. Having been in government since 1959, Singapore's ruling People's Action Party exerts unusually strong control in this former colony of the British Empire, and it's using its power to pioneer a particularly coherent, planned form of intelligent mobility.

"In Singapore, one of the most connected cities in the world, operators are investing in traffic management systems," says Macario Namie, vice president of marketing at Jasper Wireless, which provides a machine-to-machine network for Singtel in Southeast Asia. "Connectivity is impressive, not just on the mobile side, but also the fixed line. They take full advantage of their deep understanding of traffic patterns and are investing in traffic management systems, such as charge tolls based on times of traffic."


Singapore's Land Transport Authority has had a road pricing system since 1975 to control traffic flows and densities, but it's a relatively new traffic monitoring scheme called J-Eyes that has got smart city developers excited.

Junction Electronic Eyes (J-Eyes) is a network of surveillance cameras at junctions across Singapore. As of March this year there were 315 of them attached to traffic lights and lampposts, each acting as 'remote eyes' for operations executives at Singapore's traffic control centre. Video and photographs of congestion are automatically sent back to the control centre; those operations executives have so much data that they're able to re-route lanes, sending cars in specific directions to keep traffic flowing.

Just in case that seems no more than a jumped-up speed camera network, Singapore has a mature smartphone angle to its transport policy, with citizens able to download iPhone apps like TraffiCam SG, which provides real-time images from those J-Eyes cameras.


Songdo City: smart money

If Singapore is retrofitting smart driving thanks to strong, single-minded government, Songdo City near Incheon, South Korea is something of a corporate experiment. Entirely privately funded, this £20 billion project's key advantage is that it's starting from a green-field site; 1,500 acres of reclaimed land beside the Yellow Sea.

When it's completed in 2017, Songdo will be home to 65,000 residents and 300,000 workers and students will commute in each day. As well as an underground pneumatic waste collection system ridding the streets of dustbin lorries, and Cisco-provided super-fast broadband and TelePresence videoconferencing kiosks throughout (something that Cisco calls U.Life), Songdo will be fitted with subway trains, an extensive bus and cycle network, and water taxis on a central canal. Its close proximity to South Korea's main airport is causing some to call Songdo an 'aerotropolis'.


With the numbers of drivers in Songdo kept to a minimum, those behind the wheel will get a brand new highway spur to Seoul and underground garages – 95 per cent of cars will be kept off the streets when not in use - while both low-emitting and carpool vehicles will be given priority parking. Electric vehicle charging stations are being installed into both residential and municipal garages.

Sensors in the roads will not only measure vehicle loads and adjust traffic measures to react, but they'll also dim the LED-lit streets when there's no one around. And despite the tech-heavy design, the Songo's actual layout takes its inspirations from a trio of 'old world' cities; New York City's Central Park, the pocket parks of Savannah, Georgia, and the canals of Venice.

Still, to retro-fit this kind of tech and city design on an existing 'old' city would be tricky, though the roads to intelligently mobile cities are myriad.


Viral growth of apps

As for the UK, John Miles, chairman of the UK Automotive Council's Intelligent Mobility Working Group, reckons that infinite computing and communications power in vehicles will spark viral growth of web-powered smart apps on driver's smartphones, and other hand-held devices.

"The recent explosion of connected power is anything but 'top down'," he says. "Could this sort of anarchic development, this Darwinian evolution of systems and facilities, achieve for mobility what the top-down approach has never been able to achieve?"

Internet and mobile communications will be embedded in the next generation of smart cars, and while the machine to-machine link that will allow vehicles to respond to remote information systems is merely a bunch of sensors and a faster, more comprehensive 4G network away.

"When cars are capable of connecting with their outside environment, the day of the top-down system will be gone forever," says Miles, confident that a bottom-up, viral world of interconnected and intelligent vehicles can save the day.

"Drivers will participate in an environment of information exchange and automatic control for the benefit of all. Our cities will be retro-fitted with intelligent mobility capabilities without any need for arguments about systems, standards, and enforcement."

The terminology can be confusing, but whether it's called the Internet of Things, 'pervasive computing', telematics or smart city thinking, the advantages brought by smart car connectivity don't just concern the 'harvesting' of data, but in the mapping of urban travel patterns by predicting human behaviours in specific settings.

In short, we humans' erratic, selfish and risky behaviour behind the wheel will ultimately become predictable and controlled by central, all-knowing computers that work for the good of all citizens.

That's what the real 'big society' will be about, with the driverless car perhaps at the end of the road. For now, data-driven intelligent mobility is where the smart money is.
