Many cities are retrofitting traditional major arterials, modernizing large urban thoroughfares to be more pedestrian and bicycle friendly and respectful of the surrounding community, while meeting the needs of public transit and not unduly compromising motor vehicle travel. The major culprit in incompatible urban arterial street design is equating high speed with roadway mobility and capacity. Modernizing Large Urban Arterials for Increased Mobility will present techniques for designing our arterial roadways for community livability, while retaining reliable mobility along our most important travel corridors by controlling traffic speeds, thus permitting more comfortable and safe pedestrian and bicycle access.
