22.214.171.124: Output Roadway Information Data
This process shall transfer data to processes responsible for controlling roadway information devices such as dynamic message signs (DMS) and highway advisory radio (HAR) located at the roadside. This process shall receive inputs from other functions within ITS to control the content and manner in which DMS and HAR data is defined. The process shall be capable of outputting some or all of the following advisory data: link state data, current incidents, planned events (including multimodal crossing events), environmental conditions, wide area alerts, traffic signal indicator data, evacuation information, shelters, road closures, and highway rail intersection status. The data contains outputs used to control and monitor the status of DMS and HAR. This process shall also be responsible for the monitoring of input data showing the way in which the roadway information devices are responding to the data that they are being sent, and the reporting of any errors in their responses as faults to the Collect and Process Indicator Fault Data facility within the Manage Traffic function. This process also sends displayed messages to another process for wider dissemination. This process is also responsible for defining messages for DMS and HAR and sending configuration changes (i.e. blanking sign).
