Miami-Dade County TSMO Expansion

Project Description: Expansion of TSM&O onto County–owned arterials. This project includes upgrade of the County ATMS central system into a fully NTCIP compliant system. Also, this project includes countywide upgrade of traffic controllers from 170E Type to controllers meeting the requirements of Caltrans Unit Version 2070LX (Linux OS/NTCIP compliant software). These upgrades are being procured as part of the new ATMS system.

Project Functional Requirements (Element - Functional Object):

Miami-Dade Traffic Control 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.
2: The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.

Miami-Dade Traffic Control Center - TMC Roadway Equipment Monitoring

1: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
2: The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.

Miami-Dade Traffic Control Center - TMC Signal Control

1: The center shall remotely control traffic signal controllers.
3: The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
4: The center shall collect traffic signal controller fault data from the field.

Miami-Dade Traffic Control Center - TMC Situation Data Management

1: The center shall collect traffic probe data from vehicles via roadside field equipment.
2: The center shall collect road condition data from probe-equipped transit vehicles via transit management centers; the data may be aggregated and preliminarily processed at the sending center.

Miami-Dade Traffic Control 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.
2: The field element shall collect, process, and send traffic images to the center for further analysis and distribution.

Miami-Dade Traffic Control Equipment - Roadway Field Management Station Operation

1: The field element shall accept configuration information from the center.
2: The field element shall pass data provided by the center to local field devices and report data from the field devices back to the center.

Miami-Dade Traffic Control Equipment - Roadway Signal Control

1: The field element shall control traffic signals under center control.
2: The field element shall respond to pedestrian crossing requests by accommodating the pedestrian crossing.
3: The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
4: The field element shall report the current signal control information to the center.
5: The field element shall report current preemption status to the center.
6: The field element shall return traffic signal controller operational status to the center.
7: The field element shall return traffic signal controller fault data to the center.
8: The field element shall report current transit priority status to the center.
9: The field element shall report current intersection signal timing information to roadside equipment for transmission to connected vehicles.

Miami-Dade Traffic Control Equipment - RSE Situation Monitoring

1: The field element shall collect traffic-related data including snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control from vehicles.

Miami-Dade Traffic Control Equipment - RSE Traffic Monitoring

1: The field element shall communicate with on-board equipment on passing vehicles to collect current vehicle position, speed, and heading and a record of previous events (e.g., starts and stops, link travel times) that can be used to determine current traffic conditions.

Vehicles - Vehicle Basic Safety Communication

2: The vehicle shall provide its location with lane-level accuracy to on-board applications.

Vehicles - Vehicle Situation Data Monitoring

1: The Vehicle shall obtain data collection parameters from Connected Vehicle Roadside Equipment.
2: The Vehicle shall collect data collection parameters from Centers.
