Sarasota County Bluetooth Travel Time System Expansion

Project Description: Expand County's existing BlueToad system to collect and calculate real–time traveler information (travel time, speed) and integrate this data with the TMC traffic website.

Project Status: Planned

Project Stakeholders:

• Manatee County Area Traffic Agencies
• Sarasota County Public Works Department
• Travelers

Project Service Packages:

• TM01: Infrastructure-Based Traffic Surveillance (Sarasota County Bluetooth Travel Time)
• TM06: Traffic Information Dissemination (Sarasota County Bluetooth Travel Time)

Project Functional Requirements (Element - Functional Object):

• Manatee-Sarasota Regional Traffic Management Center - 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.


• Manatee-Sarasota Regional Traffic Management Center - 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.


• Sarasota 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.


• Sarasota 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


• Sarasota 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.


• Sarasota County TMC - 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.


• Sarasota County TMC - TMC Situation Data Management
• 1: The center shall collect traffic probe data from vehicles via roadside field equipment.


• Vehicles - Vehicle Location Determination
• 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
