It's a deceptively small detour - a few extra turns, a few extra stops, a few extra minutes spent searching for a parking space. A delivery van maneuvers through what is meant to be a quick reroute.... and over the course of a week discovers unexpected costs.
Traffic calming exposes commercial vehicles to a loss of both time and profits, with concrete barriers forcing them to navigate extended (and often impractical) routes. Instead of achieving a straightaway service, they endure narrowed lanes and lost parking - and the cost of business suddenly becomes much higher. One Oklahoma Department of Transportation analysis estimated that a commercial truck generates approximately $0.94 for every additional mile it travels, including vehicle operating costs; while another report examined a bridge closure that impacted more than 1,800 vehicles per day, including an average of 360 trucks. The resulting detour added 11.5 miles (close to 13 minutes to each trip) and forced extra spending.
The numbers can become considerably larger when a detour affects an entire transportation network. A Minnesota DOT analysis of a road closure estimated that extending travels by just 42-minutes on a detour could generate approximately $140,000 in additional daily costs, including fuel, vehicle wear, and travel time for the collective commercial trucks and vans passing through. With each barrier erected comes a surge in expenses.
Traffic calming leaves commercial carriers struggling to find parking spaces - and keep their profit margins.
