Modernizing Federal Standards: Making the MUTCD Work for Cities

debug msg: this block is Large Text Block, Left Aligned

Did you know that one federal document dictates what nearly every street looks like in the US?

Comparison of two streets: one an illustration of a street restricted by the MUTCD (rainbow crosswalk, pedestrian signal, different types of bike facilities, red bus lanes); the other of a street permitted by the MUTCD (wide lanes, vehicles, no crosswalks or places for pedestrains)

One federal manual dictates how we build our streets. We must reform it.

It’s called the Manual on Uniform Traffic Control Devices (AKA, the MUTCD), and like many obscure regulations, it’s riddled with fundamental problems.

Right now, FHWA is in the process of updating the MUTCD for the first time in more than 10 years. Unfortunately, the currently-proposed update continues to tinker at the margins without fundamentally fixing this flawed regulation, which was last rewritten in 1971.

See NACTO’s blueprint for updating America’s street manual, and aligning it with safety, equity, and sustainable goals.

The Context:

The United States has a traffic safety crisis more severe than that of any other industrialized country. 35,000+ people die on our roadways every year, double the rate of Canada, and quadruple that of Europe. The costs of this are not borne equally; Black people were struck and killed by drivers at an 82% higher rate than White, non-Hispanic Americans.

Our streets are unsafe because of how they are designed. While all levels of government are responsible, the crisis stems in no small part from the Federal standards used to build our streets. The MUTCD, which governs all road markings, stop signs, and traffic lights in the US, prioritizes moving private vehicles fast above all other goals–like safety, climate, and access for people walking, biking, in a wheelchair, or on a bus.

Under today’s MUTCD, someone crossing a street is less important than the fast-flowing movement of cars. Often, even multiple people dying at an intersection is not enough for the MUTCD to recommend installing a walk signal.

Because of the flawed rules in the MUTCD, American streets are unsafe and unwelcoming, limiting possibilities to create the vibrant, walkable neighborhoods that people want.

Why must FHWA reframe the MUTCD? The manual limits progress and safety–and is full of absurd restrictions

The MUTCD is charged with standardizing signs and markings on US roads to promote safer conditions. Yet, after decades of tweaking the manual, rather than fundamentally fixing it, the MUTCD is now full of seemingly arbitrary and functionally dangerous rules.

As proposed, Federal standards would prohibit colorful crosswalks in the name of safety, but still endorse the 85th percentile for setting speed limits, even if engineers consider it too fast to be safe. The manual is contradictory, stifles the implementation of innovative new designs cities have developed on their streets, and is actively harming people using American streets.

How did we get here?

So why is the MUTCD full of so many seemingly arbitrary, functionally dangerous rules? First, the manual restricts the use of any new street design not thoroughly studied by academia, even when there is overwhelming real-world evidence for its application. And second, the manual uses engineering mandates to prioritize the steady flow of private motor vehicle traffic over the safety of people walking, biking, rolling, and taking transit.

What was initially a document to standardize signage on rural roads has evolved, awkwardly, to govern every street in the U.S. Every day, people in our cities and suburbs suffer the consequences, sometimes tragically, because of it. Urban streets serve a variety of functions and many users. The uniformity and rigidity of the MUTCD is valuable on high-speed highways and for critical features like stop signs and uniform traffic lights (green/yellow/red), but in its current form is unworkable in the complex, vibrant contexts of city streets.

A blueprint to update America’s street manual

The MUTCD was last comprehensively rewritten in 1971. In the 50 years since then, American cities have demonstrated that our streets serve many purposes, and that streets can be great places to walk, bike, take transit, and socialize. A new manual can reflect the realities and aspirations of what our streets can be. 

This winter, NACTO organized a campaign across our member cities and transit agencies, along with dozens of partner organizations, to call on FHWA to update the MUTCD into a proactive, multimodal safety regulation.

Since then, NACTO’s staff and 89 member cities and agencies combed through the 1,000 pages of the MUTCD and developed over 400 specific edits, which would substantially reframe the MUTCD to a safe and sustainability-first document. These edits remove the red tape between federal regulation and safe, inviting, and innovative treatments like pedestrian signals, red transit lanes, and crosswalks.

Key changes include:

  • Elevating the goal of eliminating injuries and deaths: Make safety and a safe systems approach a guiding principle of the manual.
  • Modernizing speed limits: Remove guidance recommending free-flows speeds, including the dangerous 85th percentile rule, in setting speed limits.
  • Making it safer to cross the street: Removing the red tape and hoops required for cities to install inviting crosswalks and common sense treatments like pedestrian signals. No longer have guidance that requires multiple people to die at an intersection before a pedestrian signal is ‘warranted’.
  • Promoting people over robots: Remove the manual’s proposed section on autonomous vehicles, and instead require autonomous vehicles to operate safely on the roads we already have.
  • Legalizing commonsense treatments for people walking, biking, and taking transit: Remove unnecessary restrictions and red tape for green bike lanes, red transit lanes, and vibrant crosswalks.
  • Promoting best practices for bikeways: Eliminate strict geometric design restrictions for urban bikeways and instead refer to best practices already successfully used in cities.
  • Listening to more voices: Reconcile comments and finalize the 11th edition in an inclusive and transparent manner, and develop a more expedient, open, and inclusive process for future updates.

With these changes, cities will no longer have to jump through hoops to use the cost-effective, sustainable street design elements that make streets great places to be.

Thank you to the thousands of people who pushed for better streets

There were over 25,000 comments submitted to the Federal Register during this once-in-a-decade opportunity to ask FHWA to make key changes to the MUTCD. This enormous volume of comments (a more than ten-fold increase over the last time the MUTCD was updated in 2009) demonstrates the degree to which Americans want change.

We thank every government agency, organization, and individual that made their voice heard, and the dozens of major US cities, transit agencies, and experts who submitted detailed, technical comments that underscore the high level of public concern about the poor safety record of US roads and a strong desire for FHWA to take decisive action to save lives and reduce transportation emissions.
