Low Level Function
3.4.11 Analyse Environmental Data and Implement Actions
Overview
This Function shall be capable of providing the following facilities:
(1) The ability to analyse the environmental data when it is received from the functionality managing the store of Environmental Conditions data to see if any action is needed.
(2) The ability to send the results of the analysis and any recommended action to the functionality providing the HMI for the Road Network Operator for confirmation of the action.
(3) When conformation of the recommended action is received from the functionality providing the HMI for the Road Network Operator, the ability to send the data to other functionality in the System.
(4) The ability to send a copy of the confirmed actions to the functionality that is managing the store of Environmental Conditions for loading into the data store.
(5) If included in the recommended action, the ability to send the data about the environmental conditions to the functionality in the System that provides the HMI through which it can be output to Drivers and/or Travellers.
Functional Requirements
(a) when the environmental data for analysis data flow is received, process its contents and determine if any actions are needed
(b) if as a result of (a) actions are needed, determine those that would be the most suitable and send them in the suggest environmental actions data flow to the Provide Environment Management Operator Interface function
(c) if the contents of the confirm environmental actions data flow received in response to (b) contain a negative response, re-examine the actions that could be taken and if possible suggest alternatives
(d) if the contents in (c) contain a positive response then implement the actions that were determined in (b) and send out the appropriate data flows to other Manage Traffic functionality and to functionality in other Functional Areas
(e) also put any information that needs to be output into the environmental information data flow and send it to the Output Environmental Information function.

Number | Description |
| The system shall manage road traffic in such a way that levels of environmental (i.e. atmospheric and noise) pollution may be reduced. |
| The system shall be able to monitor and record environmental (atmospheric and noise) pollution conditions, and provide an alarm when a certain threshold is exceeded. |
| The system shall enable the TCC to calculate recommended headways for the current traffic and environment conditions. |
| The system shall be able to monitor the current inter-urban traffic and weather/environmental conditions, identify incidents, assess their impact, make short term predictions, and select and initiate an appropriate mitigation strategy. |
| The system shall be able to monitor the current inter-urban traffic and weather/environmental conditions for the road network and recommend and/or set an appropriate traffic management strategy. |
| The system shall enable the traveller information service provider to receive current inter-urban traffic management, and weather, conditions and planned events. |
| The system shall enable the traveller to request and receive (anticipated) weather/environmental conditions on, or before, a planned trip. |
