Improve overall usefulness of a closed-circuit television (CCTV) camera by expanding the coverage, color-vision features, and operational availability of the camera.
Monroe County, New York's experience in ITS camera deployment and system integration.
- Expand a camera's coverage from one approach to all approaches of an intersection. Operators recommended a "fish-eye zoom" function that would expand a camera's coverage from one approach to all approaches of an intersection by displaying local detail and its surrounding global context in a single view. With this function, RTOC operators can observe traffic flow on more than one approach at a time and monitor the effect of timing adjustments in one direction while ensuring that crossing flow is not severely affected.
- Use color mode in camera to improve night time vision. During the night time, the performance of black and white mode camera was generally poor. Glare from approaching headlights was a problem to the operators. The use of color mode at all times can improve night time vision.
- Place a message on the screen indicating the availability (or unavailability) of the camera. When more than one person may need to use a specific camera at the same time, there is no way to know which individual has control of the camera other than asking those within the RTOC control room. By placing a message on the screen indicating which operator is in control of the camera, confusions of using camera can be avoided.
