City of Sarasota Passive Pedestrian Detection

Project Description: Develop a 3 tier ped treatment standard (Recall, Passive, Buttons) and implement the passive systems. Captures pedestrian activity that has not activated a manual pedestrian detection device.

Project Status: Planned

Project Stakeholders:

• City of Sarasota
• Travelers

Project Service Packages:

• TM03: Traffic Signal Control (Passive Pedestrian Detection)

Project Information Flows:

Information Flow	Source Element	Destination Element	Status
crossing call	Pedestrians	City of Sarasota Traffic Control Equipment	Planned
crossing permission	City of Sarasota Traffic Control Equipment	Pedestrians	Planned
right-of-way request notification	City of Sarasota Traffic Control Equipment	City of Sarasota TMC	Planned
signal control commands	City of Sarasota TMC	City of Sarasota Traffic Control Equipment	Planned
signal control device configuration	City of Sarasota TMC	City of Sarasota Traffic Control Equipment	Planned
vulnerable road user presence	Vulnerable Road Users	City of Sarasota Traffic Control Equipment	Planned

Project Functional Requirements (Element - Functional Object):

• City of Sarasota TMC - 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.
• 15: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements at or near signalized intersections.
• 2: The center shall accept notifications of pedestrian calls.
• 3: The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
• 9: The center shall implement control plans to coordinate signalized intersections based on data from sensors and connected vehicles.


• City of Sarasota Traffic Control Equipment - Roadway Basic Surveillance
• 5: The field element shall return sensor and CCTV system fault data to the controlling center for repair.
• 6: The field element shall collect, process, and send traffic images to the center for further wrong way vehicle entries analysis and detection.


• City of Sarasota Traffic Control Equipment - Roadway Mixed Use Crossing Safety
• 1: The field element shall collect images or sensor data for pedestrians or bicyclists and respond to pedestrian or bicyclist crossing requests via display, audio signal, or other manner.
• 2: The field element shall respond to pedestrian or bicyclist crossing requests via display, audio signal, or other manner.
• 3: The field element shall inform pedestrians and bicyclists of the status of the intersection including the amount of time left for crossing the intersection.


• City of Sarasota 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.
• 6: The field element shall return traffic signal controller operational status to the center.
