Yesterday, I made the mistake of thinking I only needed an hour to drive 11 miles in Los Angeles — and arrived 20 minutes late for my interview with Colin Beavan, No Impact Man. If I were making the trip today, I would’ve planned my day differently — because the just-released INRIX National Traffic Scorecard special report shows Los Angeles to be the most traffic congested market in the country — again.

 

Traffic congestion’s actually gone down in most of the country — but went up by 4 percent in the L.A. area in the first half of 2009. The worst intersection? Hollywood Freeway approaching Vermont Avenue. The worst time to be on the road? Thursday, 5-6 p.m.

 

But apparently, driving surface streets on a Monday at 3:20 p.m. doesn’t move so fast, either. And while taking the bus would certainly have been more eco-friendly, my trip would’ve taken me even longer than the 80 minutes driving took me. My future travel hopes rest on getting our subway system built out as quickly as possible; as of now L.A.'s rail system comes nowhere near Santa Monica, where I live. If the Subway to the Sea were running now, I could have traveled those 11 miles in under a half hour!
