This inventory element represents the deployed ITS field equipment of member agencies that send real-time transportation data to the TI-MED server. Field equipment is used to gather metrics on traffic volumes, speeds, and more.
| Functional Object | Description | User Defined |
| Roadway Basic Surveillance | 'Roadway Basic Surveillance' monitors traffic conditions using fixed equipment such as loop detectors and CCTV cameras. | False |
| Roadway Incident Detection | 'Roadway Incident Detection' provides incident detection using traffic detectors and surveillance equipment. It monitors for unusual traffic conditions that may indicate an incident or processes surveillance images, watching for potential incidents. It provides potential incident information as well as traffic flow and images to the center for processing and presentation to traffic operations personnel. | False |
| Roadway Passive Monitoring | 'Roadway Passive Monitoring' monitors passing vehicles for a signature that can be used to recognize the same vehicle at different points in the network and measure travel times. Depending on the implementation and the penetration rate of the technology that is monitored, other point traffic measures may also be inferred by monitoring the number of vehicles within range over time. Today this approach is implemented most commonly using a Bluetooth receiver that passively monitors Bluetooth devices on-board passing vehicles and license plate readers that record the vehicle license plate number, but any widely deployed vehicle communications technology or feature that can be passively monitored to uniquely identify a vehicle could be used. | False |
| RSE Emissions Monitoring | 'RSE Emissions Monitoring' collects emissions data from passing vehicles that are equipped with short range communications capability and have the capability to collect and report emissions data. The collected data includes current emissions as measured or calculated by on-board equipment. 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. | 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 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 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 |
