1. A method for increasing the traffic flow density at a traffic light intersection with a traffic light phase in which vehicles driving straight ahead and vehicles turning left may pass the traffic light intersection simultaneously, wherein the vehicles driving straight ahead have the right of way in conformity with traffic regulations and are, at least in part, equipped vehicles having a Car2X communication, an automatic longitudinal control, and a control unit, comprising:
transmitting the number of waiting vehicles turning left NIaF to the equipped vehicles driving straight ahead using the Car2X communication; and
setting time gaps between the vehicles driving straight ahead in dependence upon the number of vehicles turning left using the control unit and the automatic longitudinal control, such that a first share of the time gaps are safety time gaps, which respectively correspond to a required safety distance, and a second share of the time gaps are critical time gaps, which permit at least one vehicle turning left to turn collision-free.
