At an intersection, a detection device (e.g. camera, radar, LIDAR, LADAR, ultrasonic or sonar sensor) in a first vehicle detects a traffic signal and an evaluation unit determines signal information thereof (i.e. an indication to go, stop or slow down). If the signal information comprises an indication to stop or slow down, the evaluation unit causes the first vehicle to stop and turn off. If it comprises an indication to go, it causes it to turn on and/or move. A second vehicle identifies a parameter associated with the first vehicle and an on-board control unit controls the second vehicle to maintain the identified parameter and thereby cooperatively operate with the first vehicle (e.g. as a platoon). The parameter may be a speed, acceleration or operation of the first vehicle or an inter-vehicle distance and may be received wirelessly from the first vehicle or detected by a detection device on the second vehicle (e.g. a camera, radar, LIDAR, LADAR, ultrasonic, sonar acceleration, torque or wheel speed sensor).
