%X This paper presents a vehicle¡¯s CO2 emission reduction scheme by an ETC-assisted real-time traffic light control scheme in vehicular networks. Using Electronic Toll Collection (ETC) devices, real-time road conditions can be obtained by wireless communication between the ETC devices and the traffic lights. Adecision tree classification algorithm is used to assign the changing policy for the traffic lights, and then the optimal average waiting time can be calculated. Less waiting time will result in less fuel consumption and fewer CO2 emissions. Compared with the most widely used fixed time control, the ETC-assisted realtime traffic light control scheme has much better performances in reducing the average waiting time, improving non-stop passing rate, and reducing CO2 emission.
