5.8.5 NTCIP 1209 TSS
Support for NTCIP 1209 TSS is (for now) limited to transmitting the traffic data under
tss.tssDataCollection.dataCollectionTable and tss.tssdataCollection.dataBufferTable.
The following values can be transmitted:
volumeData(Buffer): the traffic volume / number of cars per time period
percentOccupancy(Buffer): the average occupancy of the lane per time period
speedData(Buffer): the average speed of the verhicles on the lane per time period
These values correspond to the following Wavecon UMB channels:
5002 Intvl traffic data
5004 Intvl avg. occupancy
5003 Intvl avg speed
The LCom retrieves data from the Wavetronix/Wavecon UMB module every minute,
i.e. the sample interval/period in the Wavetronix module is fixed to 60 seconds.
As the data might be retrieved via NTCIP in flexible/greater time intervals (as
specified by the settings in the respective
tss.tssSystemSetup.sensorZoneTable.sensorZoneEntry.sensorZoneSamplePeriod
entry ), the values need to be stored/buffered in the LCom.
Therefore, “Use Data Store” in System Settings (see chapter 5.13), and “Store
Values” for each of these sensor channels in Sensor Settings (see chapter 5.6) must
be activated.
Besides that, “Support TSS” must be activated in the NTCIP Agent Parameters
settings (see chapter 5.8.2.1), and for every lane an entry in the
tss.tssSystemSetup.sensorZoneTable must be created (see chapter 5.8.2.11).
