INDOT Marion County Signal and CCTV

Project Description: In 2020–2021 in Marion County, INDOT planned to install approximately 10 new CCTV cameras to monitor traffic, approximately 200 existing signals were given GPS cards to ensure properly clock synchronization, and approximately 200 existing signals had remote timing control technology added.

Project Functional Requirements (Element - Functional Object):

INDOT Arterial TMS - 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.

INDOT Arterial TMS - 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.

INDOT Arterial TMS - TMC Signal Control

1: The center shall remotely control traffic signal controllers.
15: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements at or near signalized intersections.
8: The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.

INDOT Arterial Traffic Signals and Detection - 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.
4: The field element shall return sensor and CCTV system operational status to the controlling center.

INDOT Arterial Traffic Signals and Detection - Roadway Signal Control

1: The field element shall control traffic signals under center control.
7: The field element shall return traffic signal controller fault data to the center.
