The system includes a plurality of lighting apparatuses and a first electronic device. Each of the lighting apparatuses emits light according to received power, so as to indicate whether a corresponding path is passable with the emitted light. In addition, each of the lighting apparatuses further pushes information. The first electronic device generates a request according to received information, and transmits the request to a target lighting apparatus of the lighting apparatuses. The target lighting apparatus adjusts target information pushed by the target lighting apparatus according to the request. ## Claims ### Claim 1 A traffic information interaction system, comprising: a plurality of lighting apparatuses, wherein each of the lighting apparatuses emits light according to received power and indicates whether a corresponding path is passable with the emitted light; and a first electronic device, wherein each of the lighting apparatuses pushes information, the first electronic device generates a request according to information received by the first electronic device, and transmits the request to a target lighting apparatus of the lighting apparatuses, and wherein the target lighting apparatus adjusts target information pushed by the target lighting apparatus according to the request. ### Claim 2 (depends on 1) The traffic information interaction system as claimed in claim 1, wherein the first electronic device performs a prompt operation according to the received information, and generates the request through an input operation performed on an input interface. ### Claim 3 (depends on 1) The traffic information interaction system as claimed in claim 1, wherein each of the lighting apparatuses comprises a wireless communication module for pushing the information and receiving the request. ### Claim 4 (depends on 1) The traffic information interaction system as claimed in claim 1, further comprising a main controller coupled to and providing the power to the lighting apparatuses, wherein the target lighting apparatus transmits a traffic state changing request to the main controller according to the request. ### Claim 5 (depends on 1) The traffic information interaction system as claimed in claim 1, wherein each of the lighting apparatuses comprises a power management circuit, and the power management circuit generates first electric power and second electric power according to the power. ### Claim 6 (depends on 5) The traffic information interaction system as claimed in claim 5, wherein the first electric power is connected to a light emitting module, and the second electric power is connected to a processor and a wireless communication module. ### Claim 7 (depends on 1) The traffic information interaction system as claimed in claim 1, wherein the information pushed by each of the lighting apparatuses comprises a traffic state and a remaining duration. ### Claim 8 (depends on 7) The traffic information interaction system as claimed in claim 7, wherein the information pushed by each of the lighting apparatuses further comprises a button trigger state, and the button trigger state is set in default to be an untriggered state. ### Claim 9 (depends on 8) The traffic information interaction system as claimed in claim 8, wherein when the received request is a passing request, and the traffic state in the target information indicates a passable state, the target lighting apparatus determines whether to perform a reset operation according to a reset count value, wherein if the reset count value is lower than a reset threshold, the target lighting apparatus performs the reset operation to reset the remaining duration corresponding to the passable state, and wherein if the reset count value is not lower than the reset threshold, the target lighting apparatus does not perform the reset operation. ### Claim 10 (depends on 9) The traffic information interaction system as claimed in claim 9, wherein if the reset count value is not lower than the reset threshold and the target lighting apparatus does not perform the reset operation, the button trigger state in the pushed target information is set to be a triggered state. ### Claim 11 (depends on 9) The traffic information interaction system as claimed in claim 9, wherein when the traffic state of the target lighting apparatus is changed from the passable state to a not passable state, the target lighting apparatus sets the reset count value to zero. ### Claim 12 (depends on 8) The traffic information interaction system as claimed in claim 8, wherein when the button trigger state in the target information received by the first electronic device is a triggered state, the first electronic device disables a passing request input interface, and wherein when the button trigger state in the target information received by the first electronic device is the untriggered state, the first electronic device enables the passing request input interface. ### Claim 13 (depends on 8) The traffic information interaction system as claimed in claim 8, wherein the information pushed by each of the lighting apparatuses further comprises a report state, and the report state is set in default to be an unreported state. ### Claim 14 (depends on 13) The traffic information interaction system as claimed in claim 13, wherein when the report state in the target information received by the first electronic device is a reported state, the first electronic device disables a reporting request input interface, and wherein when the report state in the target information received by the first electronic device is the unreported state, the first electronic device enables the reporting request input interface. ### Claim 15 (depends on 8) The traffic information interaction system as claimed in claim 8, further comprising: a second electronic device, disposed in a vehicle and receiving the information pushed by the lighting apparatuses, wherein when the button trigger state in the target information received by the second electronic device from the target lighting apparatus is a triggered state, the second electronic device performs a warning prompt operation.
