Not sure how they generated that stress-level map, but it seems to be an unreasonably simplistic approximation. For example, there is a dedicated bike path along the 101 from the region marked "North Bayshore" all the way past the top-left corner of the map. That entire stretch is less stressful than any place south of El Camino. By extension, most of northern Palo Alto should be dark green instead of yellow and pale…
Has something changed?
Also, the trails they show up by the bay are all super-optimstic. First of all, I think they're pretty much all gravel, they meander all over the place, and they don't GO ANYWHERE.
I live off of Marsh now and my commute involves more East Bayshore, cutting through Pete's Harbor, saying hi to the homeless people under 101, riding over the pedestrian bridge by the VW dealer, etc. I'm actually fairly lucky in that I have little traffic on my commute, but it's not exactly low-stress with a few high-traffic crossings. The worst is crossing 101 at Marsh. There's a hidden crosswalk to cross 3 lanes of the highway 84 onramp onto 101. I hate that traffic engineers decided to use the shortest-distance method and hide EVERY crosswalk behind a blind corner.. especially those on FREEWAYS, for god's sake. And then, it's pitch black at night...
