It’s not the car that matters. It’s the way you use it.

Two months ago, Google paid an estimated $1 billion for a company it said will revolutionize the way people get around. The company Google bought doesn’t make electric cars. It doesn’t make solar-powered airplanes.


It doesn’t make any vehicle at all.

Waze, the Israeli startup for which Google paid an Instagram-size bounty, is an app that aims to help drivers avoid traffic jams. Drivers use the software to report road congestion to one anotherand thus, they hope, reduce their commute times, fuel consumption, and greenhouse-gas emissions, all without ever changing the vehicles they drive. That Google paid an estimated 10 figures for Waze is the latest sign of a subtle but potentially significant shift in the future of transportation: a change not in what cars have under the hood, but in how they behave on the road.

Amid all the turbocharged talk of Priuses, Leafs, and Teslascars that curb fuel consumption by replacing your grandfather’s internal-combustion engine with a hybrid or fully electric motora bevy of technologies aim to reduce cars’ environmental impact by choreographing how, when, and where they move around. Less … than a new engine but often as technologically complex, the alternatives range from car-sharing programs to smart-traffic-light networks to GPS-enabled systems that reward drivers for commuting before or after the height of rush hour. Many of these ideas are attracting real money, and their environmental benefit could be large.

In Toronto, a university team has rolled out a software system that enables traffic lights to learn how cars and trucks flow under themand then adjust their patterns of reds and greens to move that traffic more smoothly. The software, which uses artificial intelligence techniques, is installed at 59 intersections in downtown Toronto. The team’s computer modeling says this system of “smart self-learning traffic lights” reduces travel times by 25 percent and lowers carbon-dioxide emissions by 30 percent, according to a report issued this spring by the University of Toronto’s Baher Abdulhai, who is one of the system’s designers.

A slick piece of traffic-light software doesn’t get the juices flowing as much as, say, a battery-powered car that can rocket from zero to 60 in fewer than four seconds and never needs to fill up at a gas station. (That car would be the Tesla Roadster .) But such ho-hum advances may matter more. The United States has approximately 100,000 plug-in electric vehicles on the road. according to Plug In America, an electric-vehicle advocacy group. Though that’s a big jump from a few years ago, it still constitutes just 0.04 percent of the roughly 250 million cars of all types on American roads. And given that not quite 16 million new cars are sold in the United States annually, turning over today’s auto fleet will take many years.

That means techniques that make the existing mass of cars move around more efficiently could have a much bigger near-term effect than radically environmentally friendlier ways to spin a car’s wheels.
