Cars and traffic lights are going to talk to each other

Top automakers including Volkswagen, Honda (HMC), Ford (F) and BMW (BMWYY) are experimenting with technology that allows cars and traffic lights to communicate and work together to ease congestion, cut emissions and increase safety.

Volkswagen (VLKAF) teamed up with Siemens (SIEGY) earlier in October to test a smart light system in its German hometown of Wolfsburg.
