Editing Speed limit (section)

==Technology==

Some European cars include in-vehicle systems that support drivers’ compliance with the speed limit, known as [[intelligent speed adaptation]] (ISA). ISA supports drivers in complying with the speed limit in various parts of the network, while speed limiters for heavy goods vehicles and coaches only govern the maximum speed. These systems have positive effects on speed behaviour, and improve safety. A speed-limiting device, such as ISA are considered useful by 25% of European car drivers.<ref>{{cite web|url=https://ec.europa.eu/transport/road_safety/sites/roadsafety/files/ersosynthesis2015-speedspeedmanagement25_en.pdf|title=Speed and speed management|date=2015|website=ec.europa.eu|access-date=2020-12-29}}</ref> In 2019, [[Google Maps]] integrated alerts for speed traps within its application, along with audible alerts for nearby speed cameras.<ref>{{cite web|url=https://9to5google.com/2019/01/16/google-maps-speed-trap-alerts/|title=Google Maps appears to be testing speed trap icons w/ audible alerts, rolling out for some users|last=Schoon|first=Ben|date=2019-01-16|website=[[9to5Google]]|access-date=2019-01-16}}</ref> The technology was first developed by [[Waze]], with requests for it to be removed from the application by police officers.<ref>{{cite web|url=https://consumerist.com/2015/01/26/police-ask-waze-to-remove-speed-trap-alerts-to-protect-cops/|title=Police Ask Waze To Remove Speed Trap Alerts To Protect Cops|date=2015-01-26|website=Consumerist|access-date=2019-01-16}}</ref>
