Reimagining Our Roads

In 30 years, the world’s population is expected to reach 9.8 billion. And three-fourths of us – nearly 6.8 billion people – are projected to live in urban areas.

It’s safe to say that transportation engineers have their work cut out for them.

In this episode of the ASCE Interchange, Jeremy Chrzan, P.E., PTOE, LEED AP, M.ASCE, the multimodal design practice lead at Toole Design, discusses how civil engineers are redefining city streets to improve accessibility and create healthier, more resilient communities.

“With the space we have, we need to create a more dynamic accommodating system that allows people to walk, bike, and take transit …,” said Chrzan. He believes that it’s important to refer to alternative transportation, like bikes and electric scooters, as active transportation to eliminate bias to the language.

Chrzan also describes how cities are reimagining their streets with complete street policies to raise the profile of more active transportation options.

    In reading your comments about accommodating bicycles, pedestrians, etc. That is fine where you have the space to do it. Here in rural New England many of our roads are barely 18′ wide with limited shoulders and in many cases, we have either trees or bedrock within a few feet of the edge of pavement. All of this limits our ability to accommodate anything other than vehicular We do our best to accommodate the other uses, but it is difficult at times.
