Probably yes. That is the topic of my latest Bloomberg column, here is one excerpt:
Another economic approach would consider whether the private sector, when trying to accommodate customer demand, finds that speed bumps help or hurt business. That’s a kind of market test of the concept, and indeed I often see speed bumps in shopping mall parking lots, to slow down traffic and ease the risk of accidents, including to pedestrians. The mall and parking lot owners have decided that the benefits of greater safety will attract more customers than the inconveniences of driving more slowly, and other possible costs, will put customers off. That is a seat-of-the-pants cost-benefit test, and it suggests some role for the bumps in the broader world.
That said, my personal impression is that these private-sector speed bumps are smoother and gentler than the ones I often find in neighborhoods. When it comes to local roads, the residents are actively trying to keep outside drivers away, whereas the shopping mall and parking lot owners seek the best overall environment for commercial reasons. As a tentative conclusion, I think some speed bumps are a good idea, but many are too obstructive, and perhaps they are too numerous as well; this view is supported by some recent research.
Another angle of the speed bumps debate is how much it revolves around issues of symbolic value, and that in part explains why the discussion can become so heated.
By its very design, a speed bump is a deliberate obstruction with maximum transparency as such. It is sending a message that the social goals of safety or neighborhood quiet are sufficiently important that it is worth slowing people’s progress when they travel. There are many regulations that try to make our lives safer, but most of them are hidden, with nontransparent costs, such as auto-safety regulations as applied through crash tests. A speed bump, in contrast, can work only if people notice it each time. So to the extent a society accepts speed bumps, it is visibly advertising the notion that limits to fast transportation — a symbol of progress — are acceptable in the name of safety and cozy locality.
