SAE J 2945/3:2020 PDF Download

SAE J 2945/3:2020 is a standard that establishes the requirements for Road Weather Applications. It acknowledges the significant impact of inclement weather on surface transportation systems and addresses the need for weather applications to provide additional data to infrastructure owners and operators. These applications aim to enhance the assessment of weather conditions and improve the management of transportation systems.

According to the standard, road weather data can be collected from connected vehicles and mobile devices, expanding the available sources of information. This data can then be used to provide road weather-related information to travelers through connected vehicles and devices, notifying them about hazardous conditions and enhancing safety. Additionally, the standard highlights the importance of managing road weather response on specific roadways, allowing for targeted interventions and improved efficiency.

SAE J 2945/3:2020 specifies the interface requirements between vehicles and infrastructure for weather applications. It includes detailed systems engineering documentation that maps the needs and requirements of these applications to appropriate message exchanges. The standard's main objective is to enable interoperability, ensuring that weather applications can operate seamlessly over different communication technologies. By providing a standardized framework, this standard facilitates the development and deployment of effective road weather applications that enhance the safety and management of surface transportation systems.
