The US Insurance Institute for Highway Safety (IIHS) and other members of the Road to Zero Coalition are urging vehicle manufacturers, regulators and fleet operators to promote intelligent speed assistance (ISA) and speed limiters to help curb an “epidemic of speeding” they say contributed to a spike in traffic deaths since 2020.
“Speeding causes more than a quarter of all crash deaths every year, accounting for more than 12,000 lost lives in 2021,” said Jessica Cicchino, Vice President Of Research at the IIHS. “In-vehicle technologies can be an important part of the solution.”
The IIHS said ISA uses a camera that reads posted signs or GPS mapping software to identify the prevailing speed limit and alerts drivers when they’re going too fast. Some systems also discourage speeding more aggressively by reducing power to the engine once the driver crosses the limit.
For all US drivers, the coalition’s Accelerating Technology Working Group recommends warning-based or “advisory” ISA systems as a starting point. Such systems will be required for all new vehicles in the European Union in 2024. For commercial operators and public fleets, the coalition recommends promoting ISA or speed limiters, which prevent the vehicle from exceeding a pre-set maximum speed. Some organisations already use one or the other, and the goal is to increase the number of fleets that embrace the technologies.
Echoing the recent recommendation by the National Transportation Safety Board (NTSB), coalition members will also urge the National Highway Traffic Safety Administration (NHTSA) to set performance standards for ISA technology that at least provides a warning when the vehicle exceeds the speed limit, requires all new vehicles to be equipped with ISA, and adds an ISA evaluation to NCAP.
The working group also recommended steps to promote both technologies for high-risk groups such as repeat speeding offenders and teen drivers. According to the IIHS, teens are more likely than any other age group to be speeding when they are involved in a crash.
“Cars driven by repeat speeding offenders and teens could be equipped with aftermarket ISA systems that reduce power to the engine. Smartphone apps and in-vehicle systems that warn drivers when they exceed a preset speed could also help curb teen speeding,” said the IIHS.
