"The idea that you can replace the 10 trips with one autonomous car and travel less distance, that’s the biggest misconception," says Fagnant. "You can get rid of vehicles, but not vehicle miles traveled. Without ridesharing, there's an 8 to 10 percent increase in vehicle miles traveled based on simulations we've run in Austin. You’re not replacing trips [..] the vehicle has to bounce between locations, and relocate to where it’s needed. Those in-between miles will create a lot of extra travel." — curbed.com

Now in his third year as mayor, the 44-year-old [Eric Garcetti] wants Los Angeles to be “the first postmodern city,” as he tells me, speaking in his art-filled office one morning in October.

For the first two weeks of the year, private cars with even-numbered license plates are allowed on the roads only on even-numbered dates, and those with odd-numbered plates on odd dates. The restrictions have noticeably reduced traffic in a city with 9 million cars, more than double that of a decade ago.

Waze sometimes sends drivers through little-used side streets such as Cody Road [in Sherman Oaks, Calif]...Some people try to beat Waze at its own game by sending misinformation about traffic jams and accidents so it will steer commuters elsewhere. Others log in and leave their devices in their cars, hoping Waze will interpret that as a traffic standstill and suggest alternate routes. — The Wall Street Journal

between population gains and the popularity of fully self-driving mobility services, we’ll see the total number of vehicle miles grow by 1 trillion. (Half of the 1 trillion it attributes to population growth.) For perspective, U.S. residents drove 3.1 trillion miles in 2014.
KPMG expects this growth to come from trips taken by the very young and very old, who can be immobile only due to their inability to drive. By having access to a self-driving shuttle, a world of opportunity would open up. — washingtonpost.com

Spiffing up materials the city puts out to promote safe driving “is definitely not what this is about,” Reynolds said. “It's going much deeper into the way we think about designing the streets. Art has the power to get people to sit up and pay attention and jolt them out of their normal ways of thinking. We can infuse unexpected elements into the design of the streets and the way of moving through the streets.” — The Los Angeles Times

The future of urban roads may be one where motorists, pedestrians and cyclists act as one. Spaces where these usually segregated members of the population live -- or move -- by the same rules. Most importantly, these rules would be social, not formal, to befit the increasingly popular trend of 'shared space'.
"Shared space breaks the principle of segregation," says Ben Hamilton-Baillie, a street designer who [...] brought these spaces to the U.K., which now hosts more than any other country. — cnn.com

For those who assume Los Angeles has the worst traffic in the United States: Not so fast.
Drivers in Southern California spent a whopping 80 hours sitting in traffic in 2014, according to a new report by the Texas A&M Transportation Institute and the traffic data company Inrix.
But the city with the dubious distinction of most time lost behind the wheel is Washington, D.C., researchers say, where commuters clocked 82 hours of delays in a single year. — latimes.com

The L.A.-Waze partnership is, at least in theory, an initial step toward allowing the city’s planners and engineers to regain a healthier role in mediating the kinds of longstanding cross-town conflicts that Waze has renewed and amplified.

New bike lanes certainly make life better for cyclists, but how do they affect drivers? This question is hotly debated, especially when a new bike lane replaces a lane used by vehicular traffic.
