Safety research conducted by Volvo shows that adjusting speeds to the actual traffic situation can radically reduce the risk of accidents. By alerting people to dangers ahead in a timely manner and allowing them to adapt with time to spare, connected safety technologies can support better driver behavior and boost traffic safety.
In 2016, Hazard Light Alert (HLA) and Slippery Road Alert (SRA) were first implemented in Volvo’s 90 Series cars in Sweden and Norway. Now, they come as standard on all new model year 2020 Volvos and can be retrofitted on selected earlier models.
As soon as any equipped Volvo switches on its hazard lights, the HLA sends a signal to all nearby Volvo cars connected to the cloud service, warning drivers to help avoid potential accidents. This is particularly useful on blind corners and over the crest of hills in the road.
SRA increases the driver’s awareness of both current road conditions and those on the road ahead by anonymously collecting road surface information from cars further ahead on the road and warning drivers in advance of approaching slippery road sections.
