The minimum required number of video cameras depends on the configuration of the pedestrian crossing (number of traffic directions, number of lanes in each direction, spacing between lanes, and the availability of mounting structures), as well as on the technical specifications of the video cameras.
To ensure basic operation of the Software for detecting violations of the type “Failure to yield to pedestrians,” it is sufficient to install two video cameras per each controlled direction.
To minimize occlusion within the camera field of view, it is recommended to:
Use one LPR camera per two traffic lanes in each direction to monitor vehicle movement in braking zones and to capture front license plates of vehicles;
Use one PED camera per two traffic lanes in each direction to monitor pedestrian movement.
The use of additional video cameras is recommended in cases where an additional observation angle is required and to enhance the evidentiary base when generating evidence materials.
Therefore, if it is necessary to monitor both directions of vehicle movement on a road section with four traffic lanes (two lanes in each direction) where a pedestrian crossing is located, it is required to install two LPR cameras and two PED cameras.
