The data further includes a plurality of cumulative values corresponding respectively to the time slots and a plurality of maximum values related respectively to the cumulative values. The method includes steps of: in response to receipt of a message for reserving a desired time slot selected from among the time slots, changing the cumulative value and the maximum value that correspond to the desired time slot respectively to a first value and a second value; and performing procedures to update the appointment data related to two groups of the time slots that are in the reservation session and that are respectively after the desired time slot and before the desired time slot.

Abstract: A vehicle detection method is implemented by an electronic device. The electronic device controls at least one image capture device to capture images of a road intersection governed by a traffic light, and to capture data as to vehicles using the road intersection. The traffic light includes at least one of a red light and a green light. By analyzing the images and vehicle data, the electronic device detects and identifies a vehicle illegally crossing the road intersection.
