Traffic intensity on roads

The traffic intensity is a function value which affects calculations related to traffic. Some use-cases require these values to be updated dynamically. This can be done per neighborhood. (In this example, the neighborhood in question has the ID 1.)

UPDATE_BUILDING_TRAFFIC_FLOW_WHERE_CATEGORY_IS_ROAD_AND_NEIGHBORHOOD_IS_1

  • UPDATE_BUILDING: We're changing an attribute of a building.
  • TRAFFIC_FLOW: The attribute we are changing is the TRAFFIC_FLOW, which is the technical name of a function value.
  • CATEGORY_IS_ROAD: We only want to update this value on roads.
  • NEIGHBORHOOD_IS_1: We are updating only in this specific neighborhood. Nothing outside the neighborhood is updated by this statement.
