This paper analyzes the impact of providing car drivers with predictive information on traffic signal timing in real-time, including time-to-green and green-wave speed recommendations. Over a period of six months, the behavior of these 121 drivers in everyday urban driving was analyzed with and without access to live traffic signal information. In a first period, drivers had the information providing service disabled in order to establish a baseline behavior; after that initial phase, the service was activated. In both cases, data from smartphone and vehicle sensors was collected, including speed, acceleration, fuel rate, acceleration and brake pedal positions. We estimated the changes in the driving behavior which result from drivers' receiving the traffic signal timing information by carefully comparing distributions of acceleration/deceleration patterns through statistical analysis. Our analysis demonstrates that there is a positive effect of providing traffic signal information timing to the drivers.
