Method and device for release time measurement in a traffic-dependent controllable traffic signal system

摘要

The invention relates to a method and an associated device for release time measurement in a traffic-dependent controllable traffic signal system (1) at a traffic junction (4) having at least two inlets (5) of vehicles (50), comprising the following steps: detecting vehicles (50) respectively during a release phase (104) by means of a respective detector field (3-1) at the inlets (5) of the traffic node (4), determining a time gap (107) between two consecutively detected vehicles (50) by means of an evaluation and control device (7) Comparing the determined time gap (107) with a predetermined time gap limit value (108) by means of the evaluation and control device (7); adjusting a duration of the release phase (104) as a function of the comparison result by means of the evaluation and control device (7) the release phases (104) a speed of the vehicles (50) is determined at the respective inflow (5) and wherein on the basis of the determined speed by means of the evaluation and control device (7), a selection is made between the detector field (3-1) and at least one further detector field (3-2 to 3-n) at the corresponding inflow (5), so that the time gap (107) is detected and determined in each case by means of the detector field (3-1 to 3-n) selected for the inflow (5).
