Cities on six continents are celebrating Park(ing) Day today, now in its tenth year of temporarily transforming curbside space for cars into public spaces for people. Some of the pop-up parks that caught our eye this Park(ing) Day include:

A growing number of mayors want to make big strides on bike policy, and they need smart advocates to help them do it.

Earlier this month, Streetsblog went on a streak about "shared space" -- the idea that some streets can work better when, instead of using curbs and traffic signals to separate users, pedestrians get priority using subtle but effective visual cues. We interviewed a key shared space messenger, Ben Hamilton-Baillie; we showed off built examples in Pittsburgh and Batavia, Illinois; and we discussed the potential of shared space to transform the narrow streets of New York City's Financial District.

All across America, cities are investing in new transit lines. Which of these routes will make the biggest impact by attracting large numbers of new riders? A landmark report from a team of researchers with the University of California at Berkeley identifies the factors that set successful transit investments apart from the rest.

"Recovering architect" and street design expert Ben Hamilton-Baillie launched a broadside against the rules of traffic engineering during a plenary speech to the Congress for the New Urbanism's recent annual meeting in Buffalo. Baillie urges widespread adoption of "shared space" -- a design concept popularized by Hans Monderman over the past generation in the Netherlands that has only just begun to make headway in the United States.

The Senate Environment and Public Works Committee once again delayed the release of its six-year reauthorization bill, a follow-up to the MAP-21 bill that expires September 30. Committee Chair Barbara Boxer had initially promised to unveil the legislative text early this week, then today, and now is promising to release the bill next Monday, with a markup scheduled for next Thursday.

Any bicyclist knows that maps can be quite deceiving at first glance. The first time I tried to traverse San Francisco on a bicycle, I foolishly set out from the bike-rental shop on Fisherman's Wharf with a basic street map, and decided that I'd avoid downtown traffic by heading south across the grid. While I was correct that the city's connected street grid offered many direct routes, I neglected to notice the huge ridge of Pacific Heights looming directly ahead, or the numerous full-stop intersections along the way that would further sap my momentum.

University of Chicago economist Casey Mulligan, over at the New York Times' Economix blog, dug up a 2012 study by Cheng Cheng of Texas A&M University that tells the world nothing new about the currently confused state of laws against distracted driving, and in particular bans on handheld phone use. "Perhaps lawmakers overestimated the benefits of regulating this sort of driver behavior," Mulligan writes. Or perhaps lawmakers didn't pass laws that effectively protect vulnerable road users from dangerous, distracted drivers.
