Boston Globe -- Waze, the smartphone app that maps out faster routes using traffic information submitted by its users, is now using City of Boston data on crashes to alert drivers to the most dangerous intersections.

As part its campaign to eliminate fatal crashes, the city partnered with Waze to let people know when they are passing through areas with the highest rates of traffic collisions. The app warns motorists to drive cautiously and slowly when approaching the intersections.

Waze announced the partnership on Wednesday as part of a nationwide launch of the new feature. Four other major US cities — New York, Los Angeles, San Francisco, and Washington D.C. — are participating.
