Ohio Turnpike Connected Vehicles Roadside Equipment

Status

Existing

Description

This element represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.

Functional Objects

Functional ObjectDescriptionUser Defined
RSE Automated Vehicle Operations'RSE Automated Vehicle Operations' includes the field elements that monitor and control access to and egress from automated lanes. It monitors and coordinates automated vehicle operations within the lanes. These lanes support vehicles operating in platoons with short headways.False
RSE Communications Relay'RSE Communications Relay' provides message relay services that extend effective communications range to improve communications systems performance and robustness. It also supports safey applications such as wrong way vehicle detection and other applications where roadside communication of warnings beyond DSRC range are needed to compensate for high speeds or line of site/RF interference challenges.False
RSE Communications Support'RSE Communications Support' supports secure, reliable communications with other connected devices. It provides the communications functions that add a timestamp, the message origin, and a digital signature in outbound messages and processes, verifies, and authenticates the same fields in inbound messages. It also encrypts (outbound) and decrypts (inbound) sensitive data.False
RSE Data Subscription Management'RSE Data Subscription Management' manages data subscriptions for an RSE. It provides access to a catalog of available data, manages the necessary identification information and rules that govern the data subscriptions, supports communications with data providers to collect data per the subscription rules, and makes the data available to other RSE applications. It supports different mechansims for collecting data including one–time query–response as well as publish–subscribe services.False
RSE Device Management'RSE Device Management' provides executive control and monitoring of the RSE hardware and installed software applications. It monitors the operational status of the hardware and other attached field devices and detects and reports fault conditions. A back office interface supports application installation, upgrade, and configuration as well as remote control of the operating mode and hardware configuration settings and initiation of remote diagnostics. A local interface is provided to field personnel for local monitoring and diagnostics, supporting field maintenance, repair, and replacement.False
RSE Environmental Monitoring'RSE Environmental Monitoring' collects environmental situation (probe) data from passing vehicles that are equipped with short range communications capability. The collected data includes current environmental conditions as measured by on–board sensors (e.g., ambient temperature and precipitation measures), current status of vehicle systems that can be used to infer environmental conditions (e.g., status of lights, wipers, ABS, and traction control systems), and emissions measures reported by the vehicle. The functional object collects the provided data, aggregates and filters the data based on provided configuration parameters, and sends the collected information back to a center for processing and distribution. This functional object may also process the collected data locally and issue short–term road weather advisories for the road segment using short range communications.False
RSE Map Management'RSE Map Management' provides the map functionality necessary to support map data updates to passing vehicles. It collects current map and geometry data and provides current map and geometry data to connected vehicles.False
RSE Position Correction Support'RSE Position Correction Support' broadcasts differential positioning data to enable precise locations to be determined by passing vehicles, supporting Connected Vehicle applications that require highly accurate positioning. The differential positioning data may be calculated directly by a precisely located RSE that is operating as a reference station or received from an external reference station and relayed to passing vehicles.False
RSE Privacy Services'RSE Privacy Services' operates as a proxy, replacing the mobile device's network address with the RSE's, and tagging the message so that it can return replies to the mobile device.False
RSE Situation Monitoring'RSE Situation Monitoring' is a general functional object that supports collection of traffic, environmental, and emissions data from passing vehicles. The data is collected, filtered, and forwarded based on parameters provided by the back office. Parameters are provided to passing vehicles that are equipped to collect and send situation data to the infrastructure in snapshots. In addition, this object collects current status information from local field devices including intersection status, sensor data, and signage data, providing complete, configurable monitoring of the situation for the local transportation system in the vicinity of the RSE.False
RSE Support Services'RSE Support Services' provides foundational functions that supports data collection, management, and distribution. It coordinates with Object Registration and Discovery to maintain its registration with respect to location/geographic scope and credentialing information. It maintains the necessary security credentials, authorizations, and associated keys to support communications in the connected vehicle environment. It maintains precise location and time information to support other services.False
RSE Traffic Monitoring'RSE Traffic Monitoring' monitors the basic safety messages that are shared between connected vehicles and distills this data into traffic flow measures that can be used to manage the network in combination with or in lieu of traffic data collected by infrastructure–based sensors. As connected vehicle penetration rates increase, the measures provided by this application can expand beyond vehicle speeds that are directly reported by vehicles to include estimated volume, occupancy, and other measures. This object also supports incident detection by monitoring for changes in speed and vehicle control events that indicate a potential incident.False
RSE Traveler Information Communications'RSE Traveler Information Communications' includes field elements that distribute information to vehicles for in–vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the short range communications equipment that provides information to passing vehicles.False
RSE Trust Management'RSE Trust Management' manages the certificates and associated keys that are used to sign, encrypt, decrypt, and authenticate messages. It communicates with the Security and Credentials Management System to maintain a current, valid set of security certificates and keys and identifies, logs, and reports events that may indicate a threat to Connected Vehicle Environment security.False
