Traffic alone produces 10 million tons of CO2 a year in London, accounting for 20 % of all the Carbone Dioxide immediately in the British capital. London city planners are partnering with Siemens to rise to the challenge of managing massive volumes of traffic and enhancing mobility while minimizing environmental impact. Siemens' answer is complete mobility and integrated transportation concept that provides highly efficient mobility solutions by elevating and intelligent recombining the specific advantages of rail, bus, car and air travel.
