Method for controlling traffic flow at crossing or at junction of roads, involves deducing behavior reference from prediction for driver of vehicles finding driving direction ahead of crossing, and signalizing reference to driver

摘要

The method involves detecting vehicles (51-54) i.e. car, in a preset environment around a crossing (21). A prediction for occupancy of a preset area (31) behind the crossing on a road (11) is determined in a preset direction relative to the crossing from positions of the detected vehicles. Behavior reference is deduced from the prediction for a driver of the vehicles finding a driving direction ahead of the crossing and running in the preset area. The reference is signalized to the driver by a set of lights (41, 42), and is converted into acoustical or optical signal for the driver. Independent claims are also included for the following: (1) a computer program product comprising instructions for performing a method for controlling traffic flow at a crossing of a road or at a junction of another road in the former road (2) a device for controlling traffic flow at a crossing of a road or at a junction of another road in the former road.
