One of the things I really like about this study is that it captures not only road congestion but where the drivers enter into, and exit, the freeway system. And it reconfirmed for me yet again that starting/ending in Sunnyvale is reasonably optimized for working in the 'valley' part of Silicon Valley.
The problem I have is the study didn't fully factor in road layout/design. Highway 85 here in the Valley spans from the south Valley up to 101 in Mountain View. Within months of opening, it was a recurring traffic jam. Boom or bust in the valley, traffic let up a little in the bust, but the road is congested pretty much from 6:30am until 9:30/10am in the morning. Intersections of 85/280/101/237 at the north end impact traffic northbound in the morning. 85/280 impacts southbound in the evening.
Again - patterns persisted during both the last two booms and busts.
