Ohio DOT Connected Vehicle Roadside Equipment to Ohio DOT Traffic Signal Control Systems Interface Diagram

Architecture Flow Definitions

equipment control commands  (Planned)  Applicable ITS Standards

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

intersection management application info  (Planned)  Applicable ITS Standards

Intersection and device configuration data, including intersection geometry, and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

intersection management application status  (Planned)  Applicable ITS Standards

Infrastructure application status reported by the RSE. This includes current operational state and status of the RSE and a log of operations.

intersection safety application info  (Planned)  Applicable ITS Standards

Intersection and device configuration data, including intersection geometry, and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

intersection safety application status  (Planned)  Applicable ITS Standards

Infrastructure safety application status reported by the RSE. This includes current operational state and status of the RSE and a record of intersection safety issues identified and alerts and warnings issued.

rail crossing application info  (Planned)  Applicable ITS Standards

Rail crossing and device configuration data and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

rail crossing application status  (Planned)  Applicable ITS Standards

Rail crossing application status reported by the RSE. This includes current operational state and status of the RSE and a record of rail crossing events and alerts and warnings issued.

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.

situation data collection parameters  (Planned)  Applicable ITS Standards

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.

traffic monitoring application info  (Planned)  Applicable ITS Standards

Traffic monitoring application parameters and thresholds that control the filtering, aggregation, and range of measures that are collected, derived, and reported. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

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.

vehicle signage application info  (Planned)  Applicable ITS Standards

In–vehicle signing application configuration data and messaging parameters. This flow provides a list of regulatory, warning, and information messages to be displayed and parameters that support scheduling and prioritizing messages to be issued to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

vehicle signage application status  (Planned)  Applicable ITS Standards

In–vehicle signing application status reported by the RSE. This includes current operational state and status of the RSE and a log of messages sent to passing vehicles.
