Ride-hailing service Grab has announced an expanded partnership with Here today, using the latter’s maps to provide more accurate fare estimations, ETAs and trip routing. The mapping company will provide its services in Malaysia, Indonesia, Myanmar, the Philippines, Singapore, Thailand and Vietnam, which will be combined with real-world on-road data from Grab’s 1.3 million drivers.

Here – owned by German carmakers Audi, BMW and Mercedes-Benz – is creating the most up-to-date maps to be used by autonomous driving and connected driver assistance systems, and has employed a fleet of Here True vehicles to continuously map the road network. The result is the HD Live Map, a three-dimensional representation of the physical world that is accurate down to two centimetres.

Aside from its maps, Here will also provide its places of interest (POI) database gathered through public sector and enterprise partners such as Samsung, Amazon and Microsoft, as well as real-time traffic data sourced from vehicles and devices connected to its network.

Forming the backbone of the collaboration is Here’s Matrix API, which enables Grab to improve the way drivers are assigned to passengers. The Basic Routing API will also provide passengers with more reliable ETAs and corresponding fare estimations.

Grab says that the data-sharing partnership will help it overcome the challenges of operating in rapidly-developing countries such as Myanmar and the Philippines, which have no established national address system. To that end, Here has embarked on a two-year, 45,000 km mission to create the first ever comprehensive digital map of the Philippine road network, which it has almost completed.

“South East Asia is developing quickly, with new roads and new rules emerging every day. By layering local map data on top of Here’s comprehensive location data, we can optimise driver-passenger interactions and further streamline our backend dispatch systems,” said Grab’s head of product Jerald Singh.

Here APAC director Mark Whitmore added, “We’re proud to support Grab’s fast evolving platform and growing network of passengers, drivers and new service lines with our robust and flexible on-demand location platform. We look forward to helping Grab streamline pick-up and drop-off processes, provide reliable ETAs and ultimately improve traffic management in underserviced cities like Yangon.”
