Miami-Dade Transit Operational System Replacement Project

Project Description: This project will upgrade the Miami–Dade Transit AVL System. This will include an upgrade of a new communication system and on–board infrastructure. In addition, this project will upgrade the transit signal priority capabilities of Miami–Dade Transit, add new signage at bus stops, upgrade the bus control center, and include real–time transit information for customers on 9 bus routes.

Project Functional Requirements (Element - Functional Object):

• Miami-Dade Traffic Control Center - TMC Multi-Modal Coordination
• 1: The center shall respond to requests from transit management centers for signal priority at one or more intersections along a particular transit route.


• Miami-Dade Traffic Control Center - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 10: The center shall adjust signal timing in respond to a signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other requests for right-of-way.


• Miami-Dade Transit Control Center - Transit Center Information Services
• 1: The center shall provide travelers using public transportation with traffic and advisory information upon request. Such information may include transit routes, schedules, transfer options, fares, real-time schedule adherence, current incidents, weather conditions, and special events.
• 4: The center shall provide transit service information to traveler information service providers including routes, schedules, schedule adherence, and fare information as well as transit service information during evacuation.


• Miami-Dade Transit Control Center - Transit Center Vehicle Assignment
• 1: The center shall assign individual transit vehicles to transit blocks.


• Miami-Dade Transit Control Center - Transit Center Vehicle Tracking
• 1: The center shall monitor the locations of all transit vehicles within its network.


• Miami-Dade Transit Control Center - Transit Garage Maintenance
• 1: The center shall collect operational and maintenance data from transit vehicles.
• 2: The center shall monitor the condition of a transit vehicle to analyze brake, drive train, sensors, fuel, steering, tire, processor, communications equipment, and transit vehicle mileage to identify mileage based maintenance, out-of-specification or imminent failure conditions.


• Miami-Dade Transit Metrobuses - Transit Vehicle On-Board Information Services
• 1: The transit vehicle shall enable traffic and travel advisory information to be requested and output to the traveler. Such information may include transit routes, schedules, transfer options, fares, real-time schedule adherence, current incidents, weather conditions, and special events.


• Miami-Dade Transit Metrobuses - Transit Vehicle On-Board Maintenance
• 1: The transit vehicle shall collect and process vehicle mileage data available to sensors on-board.
• 2: The transit vehicle shall collect and process the transit vehicle's operating conditions such as engine temperature, oil pressure, brake wear, internal lighting, environmental controls, etc.


• Miami-Dade Transit Metrobuses - Transit Vehicle On-Board Trip Monitoring
• 1: The transit vehicle shall track the current location of the transit vehicle.
• 2: The transit vehicle shall support the computation of the location of a transit vehicle using on-board sensors to augment the location determination function. This may include proximity to the transit stops or other known reference points as well as recording trip length.


• Miami-Dade Transit Metrobuses - Transit Vehicle Schedule Management
• 1: The transit vehicle shall receive a vehicle assignment including transit route information, transit service instructions, traffic information, road conditions, and other information for the operator.
• 2: The transit vehicle shall use the route information and its current location to determine the deviation from the predetermined schedule.


• Miami-Dade Transit Metrobuses - Transit Vehicle Signal Priority
• 1: The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
• 2: The transit vehicle shall send priority requests to traffic signal controllers at intersections, pedestrian crossings, and multimodal crossings on the roads (surface streets) and freeway (ramp controls) network that enable a transit vehicle schedule deviation to be corrected.


• Private Travelers Personal Computing Devices - Personal Interactive Traveler Information
• 1: The personal traveler interface shall receive traffic information from a center and present it to the traveler upon request.
• 2: The personal traveler interface shall receive transit information from a center and present it to the traveler upon request.


• Transit Kiosks - Transit Stop Information Services
• 1: The public interface for travelers shall collect and provide real-time travel-related information at transit stops, multi-modal transfer points, and other public transportation areas.
• 2: The public interface for travelers shall collect and present to the transit traveler information on transit routes, schedules, and real-time schedule adherence.


• Transit Stops/Stations Equipment - Transit Stop Information Services
• 1: The public interface for travelers shall collect and provide real-time travel-related information at transit stops, multi-modal transfer points, and other public transportation areas.
• 2: The public interface for travelers shall collect and present to the transit traveler information on transit routes, schedules, and real-time schedule adherence.
