This data flow is sent from onboard sensor functions to central processes within the Manage Transit function. It contains the operational status of the transit vehicle which is important because the levels of pollution vary according to how long the vehicle has been running, i.e. how warm is the engine, and what it is actually doing, e.g. is it stationary, or pulling away from a stop. The data flow consists of the following items each of which is defined in its own DDE:

+ vehicle_emissions_levels
+ transit_vehicle_status
