As of vs | plus version 6.2.5, statistics functions are offered in open vs | plus. The following functionality is currently available:

  • Measuring the green duration of a traffic stream
  • Counting vehicles in a traffic stream
  • Duration of the cycles


To be able to work with the statistics, the following conditions apply:

  • The functions are only offered for the traffic stream types MT (motor vehicles), MTCOC (motor vehicles with switch-on cancellation) and BI (bicycles). These functions are not activated for all other types.
  • If you want to use the "Count vehicles" function, you must also define which detectors per traffic stream are intended for this purpose. The corresponding detectors can be activated in the Detector editor in the counting point (Zählstelle) column. If several detectors are assigned to a traffic stream, the pulses of the individual detectors are totalled.  
  • For the new functions, the sequence of a traffic stream is divided into cycles. A cycle runs from the green end to the next green end of a traffic stream. During this time, the green duration of the traffic stream and, if defined, the number of rising edges of one or more detectors is counted. The duration of the cycle, the green duration and the vehicles counted are continuously saved in the current cycle.

  • At the end of a cycle, the current values are adopted as a completed cycle. If 14 cycles already exist, the values of the oldest cycle are deleted. With open vs | plus it is now possible to access these values.

  • New functions are available for reading this information.
    • Green seconds: The green seconds per hour are calculated by specifying the number of cycles and the traffic stream. You can select whether only completed cycles or the current cycle should also be taken into account.
      • r_NumGreenCycles
      • r_NumGreenUntilCurrCycle
    • Number of vehicles: The number of vehicles per hour is calculated by specifying the number of cycles and the traffic stream. You can select whether only completed cycles or the current cycle should also be taken into account.
      • r_NumVehCycles
      • r_NumVehUntilCurrCycle
    • Cycle duration: You can select whether only completed cycles or the current cycle should also be taken into account.
      • r_IntvDurVehPerH_from
