According to the email, “[w]e hope to use the data from this fun and civic-participatory event to furnish evidence for the need for more urban planning integrating mass transit, cycling, and walking. Bicycle counts are basic city planning tools that help change policy to encourage cycling. Most major US and European cities have them. This will be LA’s first, and we plan to do it right while having a good time.”
Some of our local biker/bloggers may have further insight into this issue. Otherwise, this sounds like a worthwhile endeavor to me. If you would like to have some influence in choosing the intersections to be included in the census, click here. And count me in for two bikes and a pair of feet!
