Americans are bombarded with rhetoric about the country’s failing transportation infrastructure. We hear horror stories about crumbling bridges, eroded pavement on highways, and a lack of sidewalks connecting communities. Peel away the partisan talking points and there is a common thread among most lobbying efforts: Government will own and operate some or all of the […]

“Street capacity” is usually defined as the amount of moving vehicles that can be pumped through in a given period of time. Here’s another definition for street capacity: the performance of a street; a measurement of a street’s ability to maximize economic development and livability consistent with its context.

He kicks off with a description of the deadly duo: travel projection models and level of service performance metrics. And for the fellow geeks who can’t get enough of this stuff, here’s a bonus video: Toth interviewed by Streetsblog […]

The communities along the corridor wanted a main street through their towns, not the high-speed/grade-separated arterial that was on the shelf. They happened to have well-connected advocates and won the battle […]
