Project Functional Requirements (Element - Functional Object):
-
Manatee-Sarasota Regional Traffic Management Center - Map Management
-
1: The Center shall collect Vehicle location information from Vehicles.
-
Manatee-Sarasota Regional Traffic Management Center - TMC Intersection Safety
-
1: The center shall provide current intersection safety status information.
-
5: The field element shall be capable of configuring roadside equipment to perform the collection and transmission of information to support intersection safety.
-
Manatee-Sarasota Regional Traffic Management Center - TMC In-Vehicle Signing Management
-
1: The center shall format and output sign information such as traffic and road conditions to field equipment that supports in-vehicle signage communications.
-
2: The center shall format and output advisory information, such as detour information, wide-area alerts, work zone intrusion information, and other special information to field equipment that supports in-vehicle signage communications.
-
3: The center shall monitor and manage output of indicator and fixed sign information, including static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal states and local conditions warnings identified by local environmental sensors) by field equipment that supports in-vehicle signage communications.
-
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.
-
Manatee-Sarasota Regional Traffic Management Center - TMC Roadway Warning
-
2: The center shall identify hazardous road weather and surface conditions.
-
3: The center shall identify hazardous traffic conditions including queues.
-
5: The center shall issue control commands to field equipment warning drivers approaching the identified hazardous conditions.
-
7: The center shall have the capability to receive real-time traffic (including location and speed), road conditions (e.g. ice, wet, etc.), and weather data (clear, rainy and snowy) from connected vehicles.
-
8: The center shall generate appropriate queue response strategies that include speed reduction, lane change, or diversion recommendations based on local traffic, weather, and roadway conditions.
-
9: The center shall use collected data to detect the location, duration, and length of queue propagation, as a result of significant downstream speed reductions or stopped traffic.
-
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 Field Equipment - RSE Communications Relay
-
1: The field device shall be capable of relaying safety related messages, such as detection of wrong- way vehicles, to other connected vehicle field devices.
-
2: The field device shall be capable of relaying safety related messages, such as detection of wrong-way vehicles, to equipped vehicles.
-
Sarasota County Field Equipment - RSE Intersection Safety
-
2: The roadway equipment shall communicate with approaching vehicles to alert and warn drivers of potential stop sign, red light, and non-motorized user crossing conflicts or violations.
-
3: The roadway equipment shall collect vehicle path information sent by a vehicle.
-
5: The roadway equipment shall send to Connected Vehicles intersection signal timing information in order for the vehicle to determine if it will safely cross the intersection given its current speed and location.
-
6: The roadway equipment shall send to connected vehicles a warning if an intersection violation appears to be imminent.
-
7: The field element shall collect current conflict monitor and intersection control data from the traffic signal controller.
-
Sarasota County Field Equipment - RSE Queue Warning
-
1: The field equipment shall communicate with the connected vehicles to gather real-time vehicle-collected data including vehicle speed, location and localized weather condition from the vehicle network.
-
2: The field equipment shall communicate queue response strategies (speed reduction, lane change, diversion recommendations) to the vehicle.
-
Sarasota County Field 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.
-
2: The field element shall aggregate and forward collected probe information to the center.
-
Sarasota County Field Equipment - RSE Traveler Information Communications
-
2: The field element shall distribute advisory information, such as evacuation information, wide-area alerts, incident information, work zone intrusion information, recommended speed limit and other special information to passing vehicles using short range communications, under center control.
-
Vehicles - Vehicle Queue Warning
-
2: The vehicle shall receive queue warning messages from infrastructure systems.
-
4: The vehicle shall communicate queue warnings and queue characteristic information based on vehicle’s distance to end of queue, (length of queue, lane(s) impacted, other descriptions of the queue condition) to the driver.
-
Vehicles - Vehicle Traveler Information Reception
-
3: The vehicle shall receive indicator and fixed sign information including static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal and traffic meter states and local conditions warnings identified by local environmental sensors).
