The Latent Demand For Bike Lanes

I took one economics course as an undergraduate. What did I learn? Well, there is a subject at which I am worse than I am at math, which is saying something. Oh, and I learned a few terms that come up every now and again, including “induced demand” and “latent demand.”

The former term refers to, among other things, what happens when new roads are built. Contrary to what people expect—and, too often, planners and politicians promise—building new roads or adding traffic lanes doesn’t ease congestion. Instead, it induces people to drive for short trips and on occasions when they otherwise might not have, and to move further away from their workplaces, schools and other places they need and want to go to—and public transportation.

On the other hand—again, counter to common perception and the claims of grandstanding politicians—bike lanes bring out latent demand. That is to say, they encourage people who wanted to cycle to their jobs, schools or favorite stores and restaurants but were reluctant because they didn’t feel safe. I imagine there are more such people than there are folks who want to drive two hours each way to work, or to put up with the hassles of driving and parking to buy some cereal and milk.

Recent research bears out what I have just said. Moreover, it shows that in many places—including my hometown of New York—bike lanes actually help to reduce the amount of time it takes to drive because bike lanes, which are often installed with left turn lanes, allow cyclists to proceed more quickly through intersections and keep cars from blocking other cars.

Research also refutes another misconception: that bike lanes are “bad for business.” They might be in the short term, which is how most small businesses owners operate because a bad month or two can ruin them (as the pandemic showed us). But loyal customers tend to return, whatever the circumstances, and stores and restaurants can gain new customers in cyclists (and pedestrians) who happen to pass by.

In other words, they benefit from latent demand. Hmm…If my economics course had included more examples like that…math would have remained my worst subject.
