LED交通信号は、通常の交通信号機でもメッセージ・パネルでも、常設型のシステムと、太陽電池パネルを備えた可搬型バッテリ駆動システムの両方でますます広く使用されています。交通信号は、基本的な表示機能(環境光センサによる輝度調整付き)に加えて、再プログラミングや監視のためにコントロール・センターに接続する場合があります。また、効果的な監視やメンテナンスを可能にするため、GPSトラッキング機能を搭載する場合もあります。

STは、幅広いLED駆動ソリューション、AC-DC/DC-DC変換ソリューションや、MEMS環境センサ、32bitマイクロコントローラSTM32、無線/有線通信ソリューションの提供により、先進的な交通信号ソリューションの開発をサポートしています。
