In a bid to improve safety at Los Angeles International Airport, more stoplights will be installed along 10 high-speed taxiways and one runway. The Federal Aviation Administration will design, maintain and pay for the entire light system, which will warn pilots when it’s safe to enter or cross a runway, airport officials said. Plans call for embedding runway status lights at six more taxiway intersections and the inner runway on the south airfield. Lights will also be installed at four additional taxiways on the north airfield. Construction is expected to begin in October and the new system will be operating by February 2012. The system is operated by a ground radar system that automatically triggers the red lights.
