How Road Diets Improve Traffic Flow

Urban planners know adding streets won’t make traffic any better, indeed adding capacity for more cars does the opposite: it makes traffic worse. The problem is that the average person (and politicians) don’t know this little quirk of urban planning. As a result we still build sub-urban areas to cater to old notions of traffic design instead of letting urban planners implement smarter, better solutions.

So what’s a solution to bad traffic? Road diets.

Today, we now know that bigger roads and extra traffic lanes do nothing to solve congestion. In fact, it tends to induce even more traffic. So we didn’t fix the congestion issues, and on top of that, we built wide roads that are relatively unsafe.

Transportation planners in the 21st century recognized that many of the roads that were overbuilt could be redesigned to calm speeding and add space for newer multimodal transportation options. And thus, the road diet was born.

How Pressure from Pedestrians and Cyclists Make Better Cities

Depending on where you live you may think streets are for people or for cars. The correct answer is that streets are for moving people and not built for the need of inanimate objects. In an interesting series of videos the Toronto Star’s Christopher Hume examines the different urban design decisions between suburban and urban neighbourhoods. The urban areas that promote cycling and walking are understandably the most vibrant, interesting, and productive (economically and culturally). The impact non-car uses can have on streets is evident and something that every city can benefit from.

Unsurprisingly, Toronto’s most vibrant streets — Queen, College, Bloor — are generally narrow car-slowing thoroughfares lined with unspectacular buildings between two and six storeys tall — hardly the stuff of vehicular convenience. The major interruptions in these mostly intact streetscapes are largely the result of clumsy modern interventions beginning in the 1950s and ’60s. Decades later in what’s now Vertical City, we still have difficulty making buildings work at street level. Architects are slowly learning, but have yet to master the skills of contextualism. They prefer the silence of the vacuum and ignore the public realm whenever possible.

Walkable Streets Solve Nearly Every Problem


Anybody who lives in a city knows that walkability of neighbourhoods is a key reason they live where they do. The attraction to mobility options, safe places, cultural and economic diversity is what keeps cities growing. Walkable spaces makes all of that happen and more!

What smoking was to the 20th century car driving is to the 21st, and people are starting to realize we need to kick the car addiction. Car culture kills people through increased obesity, awful urban planning, and pollution (not to mention collisions). Over at Fast Co. Exist they put together a list of 50 reasons why everyone should want more walkable streets.

“The benefits of walkability are all interconnected,” says James Francisco, an urban designer and planner at Arup, the global engineering firm that created the report. “Maybe you want your local business to be enhanced by more foot traffic. But by having that benefit, other benefits are integrated. Not only do you get the economic vitality, but you get the social benefits—so people are out and having conversations and connecting—and then you get the health benefits.” A single intervention can also lead to environmental and political benefits.

Here’s numbers 25 & 26 from the list:

25. It shrinks the cost of traffic congestion
The more people walk and the fewer people are stuck in traffic on roads, the more that benefits the economy. In the Bay Area, for example, businesses lose $2 billion a year because employees are stuck in gridlock.

26. It saves money on construction and maintenance
While building and maintaining roads is expensive—the U.S. needs an estimated $3.6 trillion by 2020 to repair existing infrastructure—sidewalks are more affordable. Investing in sidewalks also brings health and air quality benefits worth twice as much as the cost of construction.
