TomTom Hazard Warnings is an innovative service providing a safer and smarter road experience. While hazard services have existed for some time, TomTom’s Hazard Warnings is an industry-first push service – reducing notification time from minutes to seconds.
Leveraging the largest probe network in the automotive industry, we combine information from more than 600 million connected devices and third-party sources with unmatched traffic expertise to show drivers and vehicles what’s on the road ahead. Another novelty is the use of connected car data from the Safety Related Traffic Information (SRTI) Ecosystem. As a co-founder and partner of SRTI, TomTom Hazard Warnings is among the first to feature safety-related messages coming from OEM partners (Audi AG, BMW AG, Ford Smart Mobility Ltd., Mercedes-Benz AG, Volvo Cars and Scania).
Using a first-of-its-kind, low-latency push service, TomTom Hazard Warnings reports detected hazards to a vehicle in under five seconds. This is a breakthrough from the traditional request-response model. Typically, when an accident happens, it is loaded onto the server and then waits for the vehicle to request new information on a particular stretch of road. This can take several minutes – at high speeds that delay can translate to long distances. We push alerts out, sending detected hazard alerts to the vehicle within seconds.
TomTom Hazard Warnings harnesses industry-first push technologies to deliver hazard notifications to vehicles with low latency. It uses the OpenLRTM location referencing method to pinpoint a hazard’s exact position on the road and quickly transmit that location to the vehicle. Hazard warnings appear in driver navigation systems with display and audio alerts. In automated driving and advanced driver assistance systems (ADAS), hazard data can be used to automatically adjust a vehicle’s driving behavior.
TomTom Hazard Warnings supports a wide array of use cases, including giving drivers early visual and audio warnings of safety-critical incidents on the road ahead. It enables automated or semi-automated vehicles to make evasive maneuvers or change lanes based on upcoming hazards while also assessing current and upcoming road conditions to plan the safest routes. Reducing vehicle speed or increasing the distance between vehicles in poor road and weather conditions.
With the widest range of hazard features, fastest notifications and highest number of data sources on the market, TomTom Hazard Warnings rounds out a complete portfolio of location data, providing drivers and automated vehicles with up-to-date traffic, weather and road warnings.
