Multnomah County’s drop in auto ownership since 2007 would fill 287 acres of parking

by on June 22nd, 2016 at 9:54 am

Everyone knows Multnomah County is growing, and that most new residents are buying or bringing in cars, too. In all, state records show, 8,709 more passenger vehicles are registered in the county than there were in 2007.

But a review of car registration statistics shows that if passenger vehicle ownership were still as popular in the county as it was in 2007, it would have had to find room for 47,210 more cars and trucks instead.

How many cars are we doing without? Well, if we built a parking lot to hold the 38,501 cars that didn’t show up and assumed a standard 325 square feet per space, we’d need about 287 acres of land. For the sake of scale, that’s everything between NE Killingsworth, Skidmore, Rodney and 16th:

Even in suburban Oregon, drive-alone trips are a shrinking share of new commutes

The Portland metro area seems to have already discovered how to slow the growth of traffic congestion, the city’s bicycle planning coordinator said Friday. But it’s not investing in it very quickly.

Between 2000 and 2014, the three Oregon counties in the metro area added 122,000 new commuters. And inside the Metro urban growth boundary, less than half of that net growth came from people driving alone in cars.

Six neat charts from Metro’s new report about Portland-area transportation

Metro is the only elected regional government in the United States. It’s also got one of the most interesting government communications teams in the country. Like MLB.com, Metro hires people to write journalism-style coverage of itself.

For its latest project, a four-part “regional snapshot” about transportation, the agency pulled out all the stops: original tilt-shift photography, narrative video, text drawn from at least a dozen interviews and a whole quiver of custom-made infographics. If you want a single overview on the basics of the region’s transportation situation, I’ve never seen a better one.

We’ve explored this issue various times over the years, but you often hear people claiming otherwise so let’s share the information in a new way.

It’s relevant as the city gets ready to vote on a 10-cent gas tax that would go toward slowing the crumbling of Portland’s streets and improving their safety.

Three secrets hidden in Metro’s great new map of every local traffic collision

Last spring, the City of Portland created a fantastic new map of every fatality and major injury on its records for a decade. Now, regional government Metro has followed suit with a similar map that includes many other cities and unincorporated areas, too.

It’s not just an essential tool for understanding the context of future traffic collisions. (Should we be arguing about the specific circumstances of collision X, or does something seem to be inherently wrong with the street it happened on?) It’s also a source of some useful insights about road safety in Portland.

Seven years after ‘Platinum,’ Portland’s collision and fatality rates remain well above its peers

Though Portland has been justly praised for regularly making it through many calendar years with zero deaths of people biking, it is clearly the most dangerous of the four cities recognized as the nation’s bike-friendliest.

For the years 2009-2013, Portland’s fatality rate per bike commuter was 75 percent higher than the officially listed average for the League of American Bicyclists’ four “Platinum” cities: Portland; Fort Collins, Colo.; Boulder, Colo.; and Davis, Calif. Its reported collision rate per bike commuter was 94 percent higher.

319 people died while traveling on Oregon roads in 2011; that’s two more than 2010 and the first increase since 2005. Another bit of preliminary data shows that 15 people on bicycles were killed last year — that’s a 114% increase from the seven lives lost in 2010 and it ties the highest bike fatality total since at least 2003.

Lost in the end-of-year festivities and perhaps overshadowed by a startling number of people killed while walking on Oregon roads in 2010 (60), lies a positive statistic that deserves our attention. In 2010, there were zero fatal bicycle crashes in Portland.

According to PBOT data, this is the sixth time since 1999 that no one has been killed while riding a bike in our city (others were 1999, 2000, 2002, 2006 and 2008). (more…)
