A major European vendor of city-wide traffic management systems is porting its flagship traffic light controller to Linux and real-time Java. Signalbau Huber says its Actros controller will better meet safety-critical requirements after moving to Sysgo ELinOS/PikeOS 4.1 with Aonix's PERC real-time Java runtime.
Currently, Signalbau Huber's Actros controller is based on Debian GNU/Linux 3.2. Versions based on the new software implementation are expected to begin testing by year's end, according to Joachim Lock, R&D engineer. "The migration will enable us to move from several different CPUs to one CPU, [while] keeping security-critical functions and Linux separated," he explained.
