In a welcome sign from an industry group that has been slow to embrace street designs that prioritize walking, biking, and transit, the American Association of State Highway and Transportation Officials (AASHTO) released a statement last week saying it intends to “better address multi-modal issues.”
AASHTO’s street design manuals are highly influential and lay out standards that many engineers view as gospel. While the guidelines are supposed to be flexible, in practice they promote a highway-style approach to city streets, emphasizing the movement of motor vehicles more than a welcoming pedestrian environment or safe routes for biking.
That appears to be changing — slowly. The group’s Committee on Highways recently passed a resolution [PDF] saying its next “Green Book” — the big book of street design standards — “should address designing in and for a multi-modal transportation system.” That version is due out in 2021.
Five years may be a long time to wait, but this is an encouraging development, said Ian Lockwood, an engineer with the Toole Design Group and a voice for reform inside the profession. “‘Multi-modal issues’ is their way of saying ‘allowing and encouraging cities, counties, and states to design streets that are safer and more comfortable for people who are walking, cycling or using transit,'” he said.
