Notification system

A notification system configured to include a plurality of road lights installed along a road which are directly connected to mutually communicate with each other,

• wherein each of the plurality of road lights comprises:
• an image processing unit that detects presence or absence of a crosser who proceeds to cross the road and presence or absence of a vehicle traveling on the road, based on image data obtained by photographing the road;
• a first signal processing unit that generates a crosser detection signal when the crosser is present and transmits the crosser detection signal to the other road lights,
• a second signal processing unit that generates a vehicle detection signal when the vehicle is present and transmits the vehicle detection signal to the other road lights which exist in the traveling direction of the vehicle, and
• a notification execution unit that performs notification for alert purpose when both the crosser detection signal and the vehicle detection signal transmitted from the other road lights are received, wherein the first signal processing unit calculates an estimated crossing time required for the crosser to cross the road based on the crosser's moving speed and the width of the road, and determines which road light is to receive the crosser detection signal from among the other road lights according to the estimated crossing time.
