StreetSense metingen
StreetSense zijn sensoren van het bedrijf Mobility Sensing. De StreetSense sensoren zijn vrij nieuw en worden alleen in ’s-Hertogenbosch grootschalig gebruikt. in 2021 zijn de eerste 30 sensoren geplaatst. Dit jaar (2022) zijn er 20 aan het sensornetwerk toegevoegd. Het doel van Gemeente 's-Hertogenbosch is om de sensordata te gaan gebruiken voor inzicht in verkeerstromen. Dit monitoren wordt verplicht met de intreding van de omgevingswet. De sensoren zelf zijn vrij nieuw en daarom zijn nog niet alle functionaliteiten gevalideerd. Het aantal getelde voertuigen is gemiddeld 3% lager per dag dan metingen van tellussen. De snelheidsmetingen zijn een schatting en nog niet gevalideerd.
Datawoordenboek
| Kolom | Type | Label | Omschrijving |
|---|---|---|---|
| entity_id | text | sensor ID as imei | unique identifier of the streetsense unit e.g. 354444115341903 is the unique number of the interface this streetsense module uses to communicate. |
| recording_timestamp | timestamp | recording timestamp |
|
| receive_timestamp | timestamp | receive timestamp | |
| avgs | float8 | Average speed | Average speed of vehicles detected during the measurement interval |
| bmeh | float8 | humidity inside | bmeh = Relative humidity inside streetsense module e.g. 56.6 is 56.6 % RH |
| bmep | float8 | Air pressure inside | bmep = Air pressure inside the streetsense module e.g. 102511.91 is 1025 hPa / mBar |
| bmet | float8 | Temperature mainboard | bmet = Temperature of the sensor on the streetsense mainboard e.g. 0.71 is 0.71 degrees Celsius |
| cnt | int4 | vehicle count | cnt = vehicle count number of vehicles counted during the measurement interval |
| ec | float8 | electric conductivity | ec = measured conductivity between the two rings e.g. 0 is 0 uS |
| ec_cal | float8 | electric conductivity calculated | ec_cal = measured conductivity between the two rings, temperature compensated e.g. 0 is 0 uS |
| int_field | int4 | ||
| rssi | int4 | Received Signal Strength Indicator | rssi = Received Signal Strength Indicator e.g. -51 is -51 dBm
|
| tmpb | float8 | temperature bottom | tmpb = temperature reading of sensor below the surface inside the streetsense housing e.g. 0.52 is 0.53 degrees Celsius |
| tmpt | float8 | temperature top | tmpt = temperature reading of sensor connected to the metal ring at the top of the device e.g. 0.43 is 0.43 degrees Celsius |
| ver | text | version | version of the device |
| x_cal | int4 | magnetometer X | magnetometer calibration values e.g. -190 is the value subtracted from the magnetometer reading in order to move the result to the zero axis. The streetsense module performs a calibration every hour in order to adapt to changes in the environment e.g. a parked car nearby |
| y_cal | int4 | magnetometer Y | magnetometer calibration values e.g. -190 is the value subtracted from the magnetometer reading in order to move the result to the zero axis. The streetsense module performs a calibration every hour in order to adapt to changes in the environment e.g. a parked car nearby |
| z_cal | int4 | magnetometer Z | magnetometer calibration values e.g. -190 is the value subtracted from the magnetometer reading in order to move the result to the zero axis. The streetsense module performs a calibration every hour in order to adapt to changes in the environment e.g. a parked car nearby |
| z_threshold | int4 | Z threshold | zthreshold = magnetometer threshold for detecting vehicles e.g. 75 is 75 uT the lower the value the more sensitive the streetsense module |
| lon | float8 | ||
| lat | float8 |
