FHWA to Engineers: Go Ahead and Use City-Friendly Street Designs

The heavyweights of American transportation engineering continue to warm up to design guides that prioritize walking, biking, and transit on city streets. On Friday, the Federal Highway Administration made clear that it endorses the National Association of City Transportation Officials’ Urban Street Design Guide, which features street treatments like protected bike lanes that you won’t find in the old engineering “bibles.”

FHWA “supports the use of the Urban Street Design Guide in conjunction with” standard engineering manuals such as AASHTO’s Green Book and the Manual on Uniform Traffic Control Devices (MUTCD), the agency said in statement released on Friday. FHWA had already endorsed NACTO’s bikeway design guide last August. The new statement extends its approval to the more comprehensive Urban Street Design Guide, which also covers measures to improve pedestrian space and transit operations.

Federal approval of what were until recently considered “experimental” street designs means that more engineers and planners will feel comfortable implementing them without fear of liability.

FHWA Endorses Engineering Guide for Walkable Urban Streets

Urban streets serve a much different purpose than rural ones: They’re for walking, socializing, and local commerce, not just moving vehicles. Unfortunately, American engineering guides tend not to capture these nuances. That can lead to a lot of problems for cities. Wide roads appropriate for rural areas are dangerous and bad for local businesses in […]

NACTO Beats the Clock With Quick Update of Bike Guide

Once again, the National Association of City Transportation Officials has proven what an agile, modern coalition of transportation agencies is capable of. It was just a year and a half ago that NACTO released its first Urban Bikeway Design Guide and today, it’s released the first update to that guide. NACTO’s guide is far ahead of the industry standard, […]

FHWA to Transportation Engineers: Use the NACTO Bikeway Design Guide

In a significant step forward for American bike infrastructure, the Federal Highway Administration issued a memorandum late last month essentially endorsing street designs like protected bike lanes. In the memorandum, FHWA urges transportation engineers to use the guidelines issued by the National Association of City Transportation Officials, which contains templates for bikeway designs widely deployed […]

With New Rule, Feds Forget Their Own Best Ideas on Street Design

Antiquated, car-oriented road design guidance is losing its vise grip on our cities. Other manuals are challenging the dominance of the “design bible” issued by AASHTO, the coalition of state DOTs. But the federal government might be missing an important opportunity to enshrine street safety for all modes. Over the past few years, the Federal Highway Administration […]
