With the pandemic creating a wave of employees who have decided to work from home part-time, it might be reasonable to assume that traffic will get a lot better. After all, how can there be traffic when a big slice of workers are sitting in their home offices? Not so fast, says Michael Manville, a professor of urban planning at UCLA, who has spent his career studying traffic. Manville argues that our new lifestyles and rhythms won’t fix congested highways, but there is one way to help regulate traffic flow — a solution which will not only reduce our commute times; it will also improve the health of our communities.
