Collier County Roadside Lighting Wireless Mesh Network

Project Description: This project would utilize a wireless mesh network , provided by roadside LED lighting, to connect traffic count equipment and bluetooth travel time detectors. In places where roadside LED lights have been deployed, traffic count equipment, bluetooth travel time detectors, and other ITS equipment could be deployed without installing additional communications infrastructure, such as fiber or wireless/cell networks.

Project Status: Planned

Project Stakeholders:

• Collier County Transportation Management Services Department

Project Functional Requirements (Element - Functional Object):

• Collier County Advanced Traffic Management System - 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.


• Collier County Advanced Traffic Management System - TMC Lighting System Control
• 1: The traffic management center shall remotely control electrical lighting systems.


• Collier County Advanced Traffic Management System - TMC Passive Surveillance
• 1: The center shall collect time stamped vehicle identities from field equipment.
• 2: The center shall correlate the time stamped vehicle identities in order to calculate link travel times and derive other traffic measures.


• Collier County Advanced Traffic Management System - TMC Situation Data Management
• 4: The center shall collect probe data from payment administrative centers containing travel times between toll collection points for those vehicles equipped for electronic toll collection; the data may be aggregated and processed at the sending center.


• Collier 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.


• Collier County Field Equipment - Roadway Lighting System Control
• 1: The field element shall control lighting systems along the roadside under center control.


• Collier 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

Standards:

• US: NTCIP Lighting - SNMPv3/TLS
• US: NTCIP Transportation Sensors - SNMPv3/TLS

Project Operational Concepts:

Roles and Responsibilities

• Collier County Transportation Management Services Department
• Monitor traffic images and traffic flow data through CCTVs and field sensors, and maintain operational control of its own field equipment.
