The minimum required number of video cameras depends on the configuration of the railway 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 railway signal requirements, it is sufficient to install three video cameras per controlled direction (entry, exit, and railway signal). It is permissible to combine multiple functions within a single video camera. Such combination is allowed provided that the crossing configuration enables installation of the camera in compliance with the requirements for placement, field of view, and technical characteristics applicable simultaneously to multiple camera types.
To minimize occlusion within the camera field of view, it is recommended to use one LPR camera per two traffic lanes in each direction for monitoring entry to and exit from the crossing, as well as one TL camera per entry to monitor changes in railway signal indications and to capture both the railway signal and the vehicles crossing the entry line. For crossings with a large number of lanes in one direction, it is recommended to install additional TL cameras to ensure that both the vehicle and the railway signal are captured within the camera’s field of view.
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.
