For years, speeding has been recognised as one of the main contributing factors to deaths on our roads. Intelligent Speed Assistance (ISA) will have a huge impact on traffic safety. TN-ITS GO (Transport Network Intelligent Transport Systems) is a Connecting Europe Facility project that contributes to ISA’s success by deploying standardized advanced exchange and update mechanisms for digital map data. TN-ITS GO is planned to be a key part of the digital infrastructure of 15 European Member States and road operators by 2022. ISA’s planned introduction in all new cars sold is currently the subject of an EU proposed law.
