Debunking the Myth: Do Bike Lanes Really Slow Down Traffic?

When municipalities propose expanding bike lane infrastructure, one common argument city staff receive continuously in opposition of this move is that bike lanes slow down traffic.

However, recent research and real-world examples demonstrate the opposite: bike lanes can improve traffic flow and efficiency for everyone. Let’s break down the evidence behind why this myth needs to be put to rest.

The Research Speaks for Itself

A 2024 study by Younes et al. shows that bike lanes improve overall traffic flow by providing safe and appealing alternatives to driving. As biking infrastructure expands, more people choose cycling, particularly for shorter trips. This phenomenon, known as “mode shifting,” reduces the number of cars on the road, alleviating congestion and shortening commute times for all mode users.

The Efficiency of Road Space

Reallocating road space for cycling infrastructure makes roads more efficient at moving people. Consider this:

• A typical motor vehicle lane can carry around 2,000 people per hour.
• A bike lane in the same amount of space can carry up to 10,000 people per hour.

This staggering difference highlights the potential of bike lanes to optimize urban transportation systems, moving more people in less space.

Why It Matters

Adding just one more lane for cars has never been a long-term solution for traffic congestion. Instead, it tends to encourage more people to drive, without addressing how the increased traffic will impact feeder streets and whether they can handle the additional load.

Expanding bike lanes isn’t just about helping people on bikes; it’s about building a more efficient, equitable, and environmentally friendly transportation network. By encouraging more people to bike, cities can reduce traffic congestion, cut down on emissions, and create streets that work better for everyone and are safer for all ages and abilities.

The next time someone claims that bike lanes slow down traffic, share the facts! With safe, well-designed cycling infrastructure, cities can unlock a more efficient and sustainable future for all road users.
