Architecture Flow Definitions

device identification  (Planned)  Applicable ITS Standards

An identifier and device type designation that is used to uniquely identify a device in the Connected Vehicle Environment.

electric charging services inventory  (Planned)  Applicable ITS Standards

Aggregate information provided for electric charging stations identifying the location, operating hours, current availability, charging capacity and standards supported, access restrictions, and rates/fee structure for each station.

electric charging station information  (Planned)  Applicable ITS Standards

Information provided for electric charging stations identifying the location, operating hours, current availability, charging capacity and standards supported, access restrictions, and rates/fee structure.

environmental situation data  (Planned)  Applicable ITS Standards

Aggregated and filtered vehicle environmental data collected from vehicle safety and convenience systems including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti–lock brake status, and other collected vehicle system status and sensor information. This information flow represents the aggregated and filtered environmental data sets that are provided by the RSE to the back office center. Depending on the RSE configuration and implementation, the data set may also include environmental sensor station data collected by the RSE.

equipment control commands  (Planned)  Applicable ITS Standards

System–level control commands issued to the RSE such as reset and remote diagnostics.

local situation data  (Planned)  Applicable ITS Standards

This general flow represents the traffic, environmental, and emissions situation data that is collected from connected vehicles by an RSE, aggregated, filtered, and provided to a back–office center. It also includes data collected from ITS roadway equipment that provides current intersection and road network status for the area proximate to the RSE.

protected location and address flow  (Planned)  Applicable ITS Standards

Information flow that has had its geographic location information removed and network address information proxied to protect the privacy of the originator.

road weather advisory info  (Planned)  Applicable ITS Standards

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 212 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  (Planned)  Applicable ITS Standards

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).

RSE application information  (Planned)  Applicable ITS Standards

RSE application configuration data and parameters that are used to control applications and configure the application for a specific local use. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

RSE application install/upgrade  (Planned)  Applicable ITS Standards

This flow supports remote installation and update of software applications residing in the RSE. It supports transmission of the secure software installation files, including executable application code and associated support files.

RSE application status  (Planned)  Applicable ITS Standards

Monitoring of RSE application status including current mode, operational status, and configuration settings. It includes the status of installed applications and the application–specific data provided by the RSE.

traffic situation data  (Planned)  Applicable ITS Standards

Current, aggregate traffic data collected from connected vehicles that can be used to supplement or replace information collected by roadside traffic detectors. It includes raw and/or processed reported vehicle speeds, counts, and other derived measures. Raw and/or filtered vehicle control events may also be included to support incident detection.

traveler information application info  (Planned)  Applicable ITS Standards

Traveler information and associated parameters, filters, and thresholds that control the RSE's distribution of the traveler information to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

traveler information application status  (Planned)  Applicable ITS Standards

Application status reported by the RSE. This includes current operational state and status of the RSE and a record of traveler information distribution.
