Indian River County Travel Time Detection

Project Description: This project will deploy roadside equipment to detect travel times in Indian River County.


Project Status: Planned

Project Stakeholders:

• Indian River County Public Works Department
• Travelers

Project Service Packages:

• TM01: Infrastructure-Based Traffic Surveillance (Indian River County Travel Time Detection)

Project Functional Requirements (Element - Functional Object):

• Indian River County Field Equipment - Roadway Basic Surveillance
• 1: The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.


• Indian River County Field Equipment - Roadway Passive Monitoring
• 1: The field element shall collect, process, and send data to the center to uniquely identify passing vehicles in order to support travel time measurement


• Indian River County TMC - TMC Basic Surveillance
• 1: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.


• Indian River County TMC - TMC Passive Surveillance
• 2: The center shall correlate the time stamped vehicle identities in order to calculate link travel times and derive other traffic measures.


• Vehicles - Vehicle Location Determination
• 1: The vehicle shall provide the vehicle's current location to other in-vehicle functions.
• 2: The vehicle shall calculate the location from one or more data sources including positioning systems such as GPS, sensors that track vehicle movement, and maps used to determine the likely vehicle route.

Standards:

• (Data Not Needed) - Bluetooth
• (None-Data) - Secure Internet (ITS)
• US: NTCIP Transportation Sensors - SNMPv3/TLS
