Why the focus on capacity?
OK, let's get started
|This is an highway: wide roads without intersections, with accesses limited to ramps.|
|This is a boulevard|
|So is this|
|2 highways intersecting in a city, or...|
|...a grid of boulevards, each separated by 500 to 1 000 meters (1 600 to 3 200 feet)|
|Example from Houston, buses use parallel roads instead of the freeway to go downtown|
|Comparison of capacity between different boulevards and an highway|
|Comparison of capacity between different boulevards and an highway, motorized modes only|
What about speed?
|Average speed of trips using boulevards or highways, depending on distance, once we take into account the time to access the road|
