交通信号管理を強化すれば、当局が自動車の流れを制御して渋滞を緩和することにつながり、移動時間の短縮とCO2排出の削減を実現できます。交通信号の基本的な機能(緑色 / 赤色 / オレンジ色LEDを備えた表示ユニット)に加えて、信号機には、車両や歩行者を検出するためのセンサを装備した検出ユニットやコントローラ・ユニットを組み込むことが可能です。スマート交通信号は、交通条例違反を検出するためのカメラ、ナンバープレート認識機能、集中制御を可能にするための通信機能を装備できます。

STは、幅広い有線 / 無線通信ソリューション(Sub-GHzを含む)、パワー・マネージメントおよび電源ソリューション、LED駆動ソリューションや、低消費電力の高性能マイクロコントローラSTM32、プレゼンス / 近接 / カメラ / 環境センサ、およびMEMSマイクの提供により、先進的な交通信号システムの設計を支援しています。
