Smart cities data integration
City data comes from traffic controllers, environmental stations, public lighting, emergency dispatch and open data portals, each run by a different department or contractor.
Example use case
A municipal mobility team wants to correlate traffic flow from DATEX II feeds, air quality measurements from roadside stations and weather alerts in CAP format, so it can see whether congestion episodes coincide with pollution peaks on particular corridors.
Typical sources and transports
Common paths include DATEX II publications over HTTPS, FIWARE NGSI-LD context brokers, MQTT from sensor gateways, CKAN and DCAT open data catalogues, and BACnet/IP for municipal buildings.
What the data means
Records represent a location-bound observation: a road segment speed, a pollutant concentration with its averaging period, or a lighting circuit state. Averaging period and station location must be kept, since a one-hour mean is not comparable to an instantaneous value.
Prerequisites
Before connecting smart cities sources, prepare an inventory of systems and owners, interface documentation for each one, read-only credentials and approved network paths. Agree identifiers, units and time zones early, and name a person who can confirm values against the source during commissioning.
Limitations
Some sources are read-only bridges, such as 112 dispatch, and only aggregate or anonymised data is appropriate. Open data portals update irregularly.
ALLINLET reads and normalises data; it does not control equipment.
