The real-time vehicle sensor data model is:

Field name	Vehicle Id	Latitude	Longitude	Speed	Timestamp
Data type	String	Double	Double	Integer	Long

 

The Vehicle Id is the unique identifier of any vehicle. Generally, it is the chassis number shown in different locations for different types of vehicle.
