Update on autonomous cars: mastering city street driving

In a recent blog post, 1691 Google’s director of their self-driving car project, Chris Urmson has given an update on the technology that he says is better than the human eye.

Google’s autonomous vehicles have logged nearly 700,000 miles on the streets of the company’s hometown, Mountain View, California.  Urmson says a mile of city driving is much more complex than a mile of freeway driving, with hundreds of different objects moving according to different rules of the road in a small area.

He claims that Google has improved its software so it can detect hundreds of distinct objects simultaneously—pedestrians, buses, a stop sign held up by a crossing guard, or a cyclist making gestures that indicate a possible turn. A self-driving vehicle can pay attention to all of these things in a way that a human physically can’t—and it never gets tired or distracted.

Urmson says: “As it turns out, what looks chaotic and random on a city street to the human eye is actually fairly predictable to a computer. As we’ve encountered thousands of different situations, we’ve built software models of what to expect, from the likely (a car stopping at a red light) to the unlikely (blowing through it). We still have lots of problems to solve, including teaching the car to drive more streets in Mountain View before we tackle another town, but thousands of situations on city streets that would have stumped us two years ago can now be navigated autonomously.”

With nearly 700,000 autonomous miles under its belt, Google is growing more optimistic that it is heading toward an achievable goal—a vehicle that operates fully without human intervention.

    Researchers from two American Universities have found the provision of parking spaces can encourage automobile use and increase traffic congestion. It is well understood that increased automobile use is linked to congestion, environmental degradation and negative health and safety impacts. Trials of smart parking technology has shown a reduction in circulating traffic (looking for parking) can ease congestion and that the cost of parking can influence commuters’ modal choice. Now, researchers at the univers

    Intelligent traffic cameras open up a host of possibilities for traffic planners and controllers alike. If traffic management centres (TMCs) around the world are to cope with the increasing demands of growing traffic flows while maintaining or improving transport safety and efficiency, then video monitoring will have to be supplemented by automated warnings of incidents or deviations. According to Patrik Anderson, business development director at Swedish camera manufacturer Axis Communications, it is no
