City of Orlando Bluetooth Expansion

Project Description: This project would install Bluetooth readers and use DMS to post travel times in the City of Orlando.

Project Status: Planned

Project Stakeholders:

• City of Orlando
• Travelers

Project Functional Requirements (Element - Functional Object):

• City of Orlando 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.


• City of Orlando 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 Orlando 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).
• 4: The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.


• City of Orlando 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.


• City of Orlando TMC - TMC Traffic Information Dissemination
• 1: The center shall remotely control dynamic messages signs 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.).


• Vehicle - 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:
