Gainesville Bluetooth Automated Arterial Travel Time System

Project Description: This project will implement an arterial travel time system using Bluetooth technology.

Project Status: Planned

Project Stakeholders:

• Gainesville Traffic Operations Division
• Travelers

Project Service Packages:

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

Project Functional Requirements (Element - Functional Object):

• City of Gainesville 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


• City of Gainesville Field Equipment - Roadway Traffic Information Dissemination
• 1: The field element shall include dynamic message signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
• 3: The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
• 4: The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.
• 6: The field element shall include devices that provide data and status information to other field element devices without center control.
• 7: The field element shall include devices that receive configuration data from other field element devices, without center control.


• Gainesville Smart Traffic 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.


• Gainesville Smart Traffic TMC - TMC Traffic Information Dissemination
• 1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• 2: The center shall remotely control driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers.
• 3: The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
• 4: The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.


• Vehicles - Vehicle Location Determination
• 1: The vehicle shall provide the vehicle's current location to other in-vehicle functions.

Standards:

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