Low Level Function
3.4.3 Monitor Noise Pollution
Overview
This Function shall be capable of providing the following facilities:
(1) The ability to provide data about noise pollution in the road network.
(2) The ability to provide this data by continuously monitoring the noise levels using sensors.
(3) The ability the data about noise resulting from the monitoring to other functionality within the System for storage.
Functional Requirements
(a) the trigger input data flow shall be continuously monitored for actual measured noise levels
(b) at periodic intervals the measured noise levels shall be converted into digital data
(c) when (b) is complete, the data shall be sent to the Manage Environmental Conditions Data Store function using the output trigger flow.
