The National Transportation Safety Board asked tech companies to add the locations of grade crossings into digital maps and to provide alerts for drivers.
SAN FRANCISCO - Following directions from Google Maps on a smartphone last year, Jose Alejandro Sanchez-Ramirez turned a Ford truck, hauling a trailer, where he thought the app was telling him to go. But he ended up stuck on the railroad tracks at a poorly marked California crossing.
Soon after Mr. Sanchez-Ramirez abandoned the truck, a commuter train barreled into it, killing the engineer and injuring 32 others.
