INDOT Automated Work Zone Speed Limit Enforcement

Project Description: This project would install ITS equipment that would monitor vehicle speed traveling in the work zone area and would notify the speed information to an enforcement agency. Leveraging this information INDOT Indianapolis TMC would improve operations within and around the work zones in the state of Indiana.

Project Functional Requirements (Element - Functional Object):

INDOT Indianapolis TMC - MCM Reduced Speed Zone Warning

1: The center shall be capable of remotely control and monitor reduced speed zone warning roadside equipment operations.

INDOT Indianapolis TMC - MCM Work Zone Safety Management

1: The center shall provide remote monitoring and control of work zone safety devices - including intrusion detection devices that have been installed in work zones or maintenance areas.
3: The center shall collect status information of work zone safety device status from field equipment or the maintenance and construction vehicles.

INDOT Indianapolis TMC - TMC Speed Warning

1: The center shall provide the capability to notify an enforcement agency when vehicle speeds in the work zone are in excess of the posted speed limit or are creating an unsafe condition based upon the current environmental or traffic conditions.
3: The center shall monitor reduced speed zone warning field equipment.

INDOT Work Zone Speed Monitoring Field Equipment - Roadway Work Zone Safety

1: The field element shall include work zone intrusion detection devices that detect when a vehicle has intruded upon the boundary of a work zone, under center control.

INDOT Work Zone Speed Warning Field Equipment - Roadway Speed Monitoring and Warning

1: The field element shall include sensors to detect vehicle speeds, under traffic or maintenance center control.
3: If the speed detected by vehicle speed sensors is determined to be excessive, the field element shall provide a safe speed advisory to passing drivers via a driver information system (such as portable messages signs, field to vehicle communications to in-vehicle signing systems, etc.).
5: The field element shall monitor notify an enforcement agency when a speed violation is detected.

ISP Dispatch - Emergency Dispatch

2: The center shall store the current status of all emergency vehicles available for dispatch and those that have been dispatched.
