The Hidden Rule That Keeps 55,000 UPS Trucks From Turning Left

A UPS truck will drive three sides of a city block to reach a door forty feet to its left. Nothing has gone wrong. Around ninety percent of the turns on a typical route are right turns — the output of a decade-long engineering effort that priced the left turn in seconds and found 185 million miles a year hiding inside the arithmetic. From 1970s loop dispatch drawn on paper maps, to the routing system that reads 250 million address points a day and decides which turns a driver is permitted to make before the driver arrives. #UPS #Logistics #ORION #SupplyChain #Infrastructure #HiddenSystems #RouteOptimization #Engineering #Documentary #NullState
