This Function shall be capable of providing the following facilities:<br/><br/>(1) The collection of Floating Car Data (FCD) and Extended Floating Car Data (XFCD) from suitable equipped Vehicles that are using the urban road network.<br/>(2) The Function shall expect the data to be the raw input data provided by functionality in the Vehicle and to contain location information, time plus Vehicle identity and status data.<br/>(3) The processing of the collected data to provide actual traffic flow data, e.g. flow, speed, for the urban road network, Vehicle status data, e.g. broken down, other road related data, e.g. rain, fog, slippery road, ice and to detect incidents.<br/>(4) The checking of the collected data for coherence and consistency both for individual Vehicles and for the traffic as a whole in each segment of the urban road network.<br/>(5) The exchange of data with the Monitor Urban FCD/XFCD Source Vehicles Function to confirm that the collected data actually comes from the Vehicles whose identities are included in the data, and to discard all data except traffic flow data from Vehicles being driven safely.<br/>(6) The provision of the processed and collected data to the Detect Incidents from Data and Urban Traffic Data Management Functions.<br/>(7) The ability to make all processed data anonymous so that the movement through the urban road network of specific Vehicles cannot be identified. <br/>
(a) continuously monitor for the arrival of the data flows containing the urban floating car and other data from vehicles;<br/>(b) when either of the floating car data flows in (a) arrive, process their contents to determine traffic flow data and check this and any other data provided by in-vehicle systems for their plausibility;<br/>(c) put the vehicle identity extracted from the data flows in (b) into the urban fcd vehicle identity data flow and send it to the Monitor Urban FCD/XFCD Source Vehicle function;<br/>(d) when as a result of (c) the urban fcd error data flow is received, check to see if it includes an error indication;<br/>(e) if an error indication is found in (d) discard all the data provided by the vehicle, except that from which urban traffic flow can be determined;<br/>(f) if the safety behaviour status for urban data flow is received in (a) containing a warning of unsafe behaviour, discard all of the data from the vehicle as it will not be representative of the majority of vehicles using the urban road network;<br/>(g) if the checks in (d) and (e) are satisfactory, plus there is no warning in (f), collate and fuse the data to provide a coherent and consistent set, separating out the urban traffic flow data, other data, e.g. slippery road, fog, rain, darkness, possible incidents and ice, for easy use by other functionality;<br/>(h) fuse the traffic flow data from all vehicles so that for example, data for the same segment of the urban road network is aggregated and also fuse the data from the vehicle trip plans so that for example, the numbers of vehicle using or planning to use each segment of the urban road network is calculated;<br/>(i) send the data produced in (h) to the Provide Urban Traffic Data Management function in the data flow containing collected urban vehicle data;<br/>(j) also send the urban traffic flow data and any available data about unusual conditions, e.g. rain and low temperatures, to the Incident Detection function in the urban XFCD for incident detection data flow.<br/>
