road closure application info (Future) Selected Comm Solution
Road closure signing application configuration data and messaging parameters. This flow identifies the vehicles that may initiate the road closure. This flow also provides access lists, groups, or classifications where selected vehicles are to be allowed access to the closed area.
road closure application status (Future) Selected Comm Solution
Road closure application status reported by the RSE. This includes current operational state and status of the RSE, closure status, and a log of closure commands received and issued. For closures that allow entry by selected vehicles, this flow provides an access log identifying vehicles that have requested access with access status.
road weather advisory info (Future) Selected Comm Solution
Road weather advisories and associated configuration and control information that are used to manage the RSE. Advisories include segment–specific weather and road conditions including real–time advisories of deteriorating road and weather conditions, medium–term advisories for the next 2–12 hours, and long–term advisories more than 12 hours into the future. This flow includes a schedule for issuing the included advisories.
road weather advisory status (Future) Selected Comm Solution
Current RSE application status that is monitored by the back office center including the operational state of the RSE, current configuration parameters, and a log of advisories issued. The advisories may include advisories that are issued by the RSE based on locally collected environmental data (e.g., an ice on bridge advisory).
situation data collection parameters (Future) Selected Comm Solution
The parameters that are used to control the flow of situation data from the RSE. This flow identifies the type of data/snapshots that are requested from passing vehicles and reporting parameters such as snapshot frequency, filtering criteria (data thresholds for reporting), and reporting interval that control the type and volume of data reported to the back office center.
speed warning application info (Future) Selected Comm Solution
Roadway configuration data, current speed limits including time of day, week, or season speed limits as necessary, and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
speed warning application status (Future) Selected Comm Solution
Speed warning application status reported by the RSE. This includes current operational state and status of the RSE and a record of measured vehicle speeds and notifications, alerts, and warnings issued.
stop sign gap assist info (Future) Selected Comm Solution
