Low Level Function
6.5.3.13 Provide Data & Routes to Fleet Operators & Drivers

Overview

This Function shall be capable of providing the following facilities:

(1) The ability to provide data and routes to functionality serving Fleet Operators and Drivers at their request and contribute information about freight and hazardous goods that may be relevant to general trip planning.
(2) On request from Fleet Operators and Drivers the ability to provide data that shall comprise specific items such as pollution, traffic and weather conditions, for which the Function shall obtain the current values from the store of Road Trip Planning Data.
(3) When data is received from the Manage Freight and Fleet Operations functionality, the ability to store it in the store of Road Trip Planning Data.
(4) On request from functionality connected to the Freight Operator and Hazardous Goods Vehicle Driver the Functions the ability to prepare routes using the parameters provided in the request and data from the store of Road Trip Planning Data.

Functional Requirements

(a) continuously monitor for receipt of the freight and hazardous goods information plus on-board information and requests data flows
(b) when either of the data flows in (a) is received, send their contents to the store of Road Trip Planning Data in the data flow containing store ffm and hazardous goods data
(c) continuously monitor for receipt of any of the "request....situation" data flows
(d) when any of the data flows in (c) is received, obtain the required data from the store of Road Trip Planning Data using the data flows called store ffm and hazardous goods data and retrieve road situation data
(e) when the data in (d) has been retrieved, send it back to the Manage Freight and Fleet Operations (mffo) functionality that requested it using the "answer....situation" data flow that corresponds to the request
(f) continuously monitor for receipt of the route optimisation request data flow from the Manage Freight and Fleet Operations (mffo) functionality and the hazardous goods vehicle route request data flow from the Provide Support for Cooperative Systems (pscs) functionality
(g) when either of the data flows in (f) is received, prepare a route according to the parameters contains in the request and data that is retrieved from the store of Road Trip Planning Data using the data flows called store ffm and hazardous goods data and retrieve ffm route planning data
(h) when the route has been prepared in (g) send it back to the Manage Freight and Fleet Operations (mffo) functionality and the Provide Support for Cooperative Systems (pscs) functionality in the route and hazardous goods vehicle route response data flows respectively.
