In many cities, traffic measures are absolutely essential to improve air quality and traffic flow. But current data, instruments and means to manage transport in an environment-sensitive way are still of limited effectiveness and entail legal and image risks for traffic managers and municipal decision-makers. With a better database and intelligent, digitized systems, air quality and traffic can be optimized much more specifically. T-Systems, together with partners, offers a solution to enable precise, data-based decisions: Sustainable Traffic Management. STM helps to derive and implement the right measures to improve air quality and traffic flow in a targeted manner. STM includes an Air Quality Dashboard, a Traffic Information & Control Center and App-based Low Carbon Mobility Management.
