The transportation industry has spent 100 years planning, 设计, and building streets that favor one form of travel – the automobile – above all others.

The result is streets that are unsafe and uncomfortable for people walking, 骑自行车, and taking the bus; cities that are clogged with traffic and air pollution; and greenhouse gasses that are contributing to climate change.

The conventional approach of relying on engineering, 教育, and enforcement is no longer enough to ensure that our streets meet the needs of the 21st 世纪. It’s time to change the way we do business. We propose three new words to inspire and guide the transportation profession: ethics, 股本, 和共鸣.

Our transportation system kills 40,000 people a year in crashes (and injures hundreds of thousands more) and is responsible for more than a quarter of greenhouse gas emissions. 很明显, our industry has become too reliant on implementing solutions that meet “minimum standards” without sufficiently considering larger impacts of each design decision we make.

我们相信工程师, 景观建筑师, and planners have an ethical obligation to develop solutions that improve the safety, 健康, and welfare of the public so that fewer of our roadways are dangerous by design.



Equity means distributing resources to people in a just and impartial way. It’s not giving everyone the same thing, but rather giving everyone what they need today while considering how existing power structures have governed resource distribution in the past.

From redlining to Jim Crow to urban renewal, the built environment has often been ground zero for systems of oppression. As transportation professionals, we face constant opportunities to either dismantle or perpetuate inequities. We must recognize them and act accordingly.



Empathy is the capacity to see, 听到, and feel what another person is experiencing, from within their frame of reference. Empathy fuels a better connection with the people we serve, 这激发了创造力, 积极的, and community-focused solutions.

作为运输工程师, we have to be sure not to overlook the needs of the people our work is meant to serve. We need a human-centered approach to planning and engineering.

How can we be more empathetic?

The New E 's Podcast

How did the original three Es shape the world of transportation planning, design, and engineering? What will it take to change the systems we have in place to make better decisions in the future? Gain background, perspective, and insight on the New Es in our podcast:

  • Episode 1: Introducing the New Es
    How we can break free of professional silos and change the way that transportation professionals think about their work.
  • 第二集:伦理
    What role ethics play (or should play) in the transportation profession.
  • 第三集:同理心
    The importance of empathy in 设计 transportation systems that serve a community of travelers with different needs and capabilities.

Beyond Ethics, Empathy, and Equity

These E words are a reflection of the values that must underpin the work we do in the transportation world. But while we believe that ethics, 股本, 和共鸣 are essential to changing the status quo, they are not the only Es that could serve this purpose.

To achieve a transportation network based on human-centered design, we must be moved by 情感 to ensure that people of all ages and abilities can joyfully 经验 为他们建造的地方. Our concept for the future must start with people’s vision of their own community, not what’s left over after we’ve accommodated the needs of motor vehicle traffic.

There are other words that fit with the “E” theme. 解决 环境 challenges of climate change, energy supply, and pollution is an ethical imperative. 访问的承诺 经济 opportunities is an essential part of broader 股本 conversations. 还有一个承诺 订婚 is integral to bringing genuine empathy to our professional duties.

最终, the words we use here must reflect the human values that we wish to see in our transportation network. Only then will we be able to plan, design, and engineer change for 21st 世纪 streets that serve everyone.

Where did the Three E’s come from?

The transportation profession has been using the Three Es of engineering, 教育, 以及自 early days of the National Safety Council in 1925, when it was adopted from industrial engineering practices to manage the rise of the automobile in city planning and infrastructure investment.
