Just the Ticket? Intelligent Speed Adaptation Systems Have Been Developed and Tested for a Number of Years

This article examines the state of the art of Intelligent Speed Adaptation systems. The author begins with a test drive of a Toyota Prius that Transport for London had rigged with an Intelligent Speed Adaptation (ISA) that, depending on the mode chosen, warns drivers that they are breaking the speed limit, or ensures that the car never exceeds certain speed limits. The system senses when a vehicle is entering a 20 mph zone and slows. The head of the Road Safety Unit of Transport for London believes that if two-thirds of drivers used the technology in London alone, the number of injuries and fatalities would be cut by 10 percent. The system’s designer believes it could be retrofitted to cars for about $500. The author also provides an overview of ISA testing in the Netherlands, Sweden, and soon, in Melbourne, Australia.
