A message transmission method for a roadside equipment includes the following steps. A plurality of external sensor information is received. A road intersection sign phase information and a road map information are inputted. An object position analysis, a speed analysis, and an sign analysis in object moving direction are performed based on the external sensor information, the road intersection sign phase information, and the road map information, and a classification of dangerous objects in different groups is outputted. According to a current transmission bandwidth limitation and the classification of the dangerous objects, a dangerous object message with a higher classification of the dangerous objects is preferentially selected and transmitted within available transmission bandwidth.

Message transmission system and method for roadside equipment

An object tracking system including a plurality of electronic devices and a server platform is provided. The server platform generates a tracking message based on received event message, and sends the tracking message to at least one of the electronic devices located within a first predetermined range corresponding to the received event message. When one of the electronic devices detects a vehicle matched with one or more vehicle features of the event message according to the received tracking message, the one of the electronic devices generates and sends a notification message to the server platform.
