TomTom (TOM2), the location technology provider, Toyota Research Institute – Advanced Development, Inc. (TRI-AD) and DENSO announced a successful proof of concept demonstrating a fast high definition (HD) map-building method for roads, essential for safer autonomous driving.

This was achieved with TRI-AD test vehicles equipped with DENSO sensors, TRI-AD’s Automated Mapping Platform (AMP), and TomTom’s cloud-based transactional mapping platform. The vehicle sensors are used to collect road observations, which are converted and corrected by TRI-AD’s AMP, for input into TomTom’s cloud-based transactional mapping platform.

These crowdsourced map updates are achieved with TomTom Roadagrams, highly accurate map snippets from car sensors, that TomTom uses to ensure the TomTom HD Map reflects the reality of the road. Combined with sensor data from survey vehicles, this process enables TomTom to maintain the accuracy of its HD map.
