County and City Connected Vehicle 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
ITS Communications Support'ITS Communications Support' provides means to send and receive messages to and from other ITS Objects. It provides mechanisms for scheduling and prioritizing communications traffic. It may also provide relay functions.False
ITS Management Support'ITS Management Support' provides management of the ITS Object. This includes management of regulatory information and policies, management of application processes, management of communication system configuration and update management, communications interfaces, protocol–specific techniques to ensure interoperability such as service advertisements, communications congestion management and interference management, local device states and communications information, billing management, fault management, service level and performance monitoring.False
ITS Security Support'ITS Security Support' provides communications and system security functions to the ITS Object, including privacy protection functions. It may include firewall, intrusion management, authentication, authorization, profile management, identity management, cryptographic key management. It may include a hardware security module and security management information base.False
RSE CACC Operations'RSE CACC Operations' provides infrastructure support for formation and dissolution of strings of CACC–equipped vehicles and provides operating parameters to the strings of vehicles including string length, recommended speeds, and gaps.False
RSE Incident Scene Safety'RSE Incident Scene Safety' communicates with Connected Vehicles and Personal Information Devices carried or worn by public safety responders to detect vehicle intrusions in designated work areas at an incident scene and warn responders and drivers of imminent encroachment. Public safety responder movements are also monitored so that the responders can be warned of movement beyond the designated safe zone.False
RSE Infrastructure Monitoring'RSE Infrastructure Monitoring' collects environmental situation (probe) data from passing vehicles that are equipped with short range communications capability with particular focus on measures that may indicate infrastructure condition. The collected data includes current environmental conditions as measured by on–board sensors (e.g., ambient temperature and precipitation measures) and current status of vehicle systems that can be used to infer infrastructure condition (e.g., status of ABS, traction control systems, vertical acceleration measures) as reported by the vehicle. This functional object also supports short range communications with maintenance and construction vehicles, providing local control and monitoring of infrastructure sensors.False
RSE Intersection Management'RSE Intersection Management' uses short range communications to support connected vehicle applications that manage signalized intersections. It communicates with approaching vehicles and ITS infrastructure (e.g., the traffic signal controller) to enhance traffic signal operations. Coordination with the ITS infrastructure also supports conflict monitoring to ensure the RSE output and traffic signal control output are consistent and degrade in a fail safe manner.False
RSE Loading Zone Management'RSE Loading Zone Management' uses I2V communications to monitor and communicate with equipped vehicles approaching and/or in the loading zone. It monitors loading zone space occupancy by equipped vehicles and makes this information available to arriving vehicles and other applications. It monitors the time each vehicle spends in the loading zone and provides this information to drivers in the zone and other applications. Vehicles that have a reservation are identified on arrival and directed to the reserved spot.False
RSE Parking Management'RSE Parking Management' monitors the basic safety messages generated by connected vehicles to detect vehicles parking and maintain and report spaces that are occupied by connected vehicles. It also uses short range communications to provide parking information to vehicles.False
RSE Queue Warning'RSE Queue Warning' provides V2I communications to support queue warning systems. It monitors connected vehicles to identify and monitor queues in real–time and provides information to vehicles about upcoming queues, including downstream queues that are reported by the Traffic Management Center.False
RSE Rail Crossing Warning'RSE Rail Crossing Warning' is a connected vehicle application that improves safety at rail crossings. It communicates with wayside equipment that detects or communicates with approaching trains. It provides rail crossing warnings and train arrival information to approaching vehicles and monitors connected vehicles that may intrude on the crossing.False
RSE Road Closure Management'RSE Road Closure Management' communicates with qualified Connected Vehicles and barrier control systems to support local road closure management. It validates and requests implementation of road closure requests. During a closure, it can also support selective access to the closed area, only granting entry permission to allowed vehicles.False
RSE Traffic Gap Assist'RSE Traffic Gap Assist' provides advisory information to minor road drivers at a stop–sign controlled intersection to facilitate gap selection to proceed through the intersection. The application can be configured depending on the intersection geometry. It monitors Connected Vehicle traffic on the major road, augmenting infrastructure traffic detectors, to identify and measure traffic gaps. The intersection geometry, measured traffic gaps, and current gap assist sign displays are communicated to the connected vehicle that is navigating the intersection for use in driver advisories and warnings. The application may also collect vehicle size and performance profile from the connected vehicle to optimize the alerts and warnings to the capabilities of the vehicle and driver preferences.False
RSE Transit User Guidance'RSE Transit User Guidance' uses short range communications to provide terminal or stop–specific guidance to transit user devices that assists users in finding the right stop and the right bus. Optionally, this object can collect the transit user location and planned itinerary so that tailored guidance can be provided.False
