That is, the present invention can be equally/similarly applied even when the regions 41 and 42 are rectangular, hexagonal, etc., the shapes of the regions 41 and 42 are different from each other, or implemented in a combination different from the above colors. .

-Embodiment 1-

Referring to (a) of FIG. 4 , when the location determination unit 21 determines the location of the emergency vehicle 1, the traffic light management unit 22 reports an emergency situation to a pedestrian traffic light 4 nearby the emergency vehicle 1. A traffic signal control command for controlling the output of the indicated information may be transmitted to the traffic light controller 3.

For reference, in the present invention, information indicating an emergency situation is defined as image information output to the display unit 4a of the traffic light 4.

Specifically, the traffic light management unit 22 stores information indicating an emergency situation in advance in a storage unit (not shown), reads information indicating an emergency situation matched to the current emergency situation from the storage unit (not shown), and controls the traffic light controller (not shown). 3) can be sent.

According to the embodiment, the traffic signal control command may be generated as a control signal to output audio information together with information indicating an emergency situation.

Meanwhile, according to an embodiment, referring to (a), in the traffic signal control command, the first area 41 is activated (turned on), information on walking is disabled is output, and the emergency vehicle (in the area surrounding the first area 41) It may be to control information indicating an emergency situation related to 1) to be output. At this time, the second region 42 may be deactivated (turned off).

Information representing an emergency situation according to an embodiment may be output in at least one of a) blinking form, b) icon form, and c) text form.

The icon according to the embodiment may be pre-stored in a form in which emergency information such as an emergency vehicle shape, an exclamation mark shape, and a shape of fire can be recognized at a glance.

The shape of the emergency vehicle may be output differently for each type of vehicle. For example, each of a fire engine shape, a police car shape, and an ambulance shape may be differently stored in advance and then output.

In the case of b), icons in the shape of an emergency vehicle are output in a state in which they are spaced apart from each other by a predetermined interval in the area surrounding the first area 41, or in the case of c), each text constituting a sentence (“It is an emergency”) is output. It may be output in a state of being arranged spaced apart from each other by a predetermined interval in the area surrounding the first area 41 .

At this time, in each of a) to c), the information indicating the emergency situation may be implemented in a form that lasts for a predetermined time or some information is sequentially output.

For example, all blinkers/all icons/full text may be continuously output together for a predetermined time, or some blinkers/some icons/some text may be sequentially output.

In this case, when some blinkers/some icons/some text are sequentially output, they may be output clockwise or counterclockwise as time elapses.

According to an embodiment, at least a part of each of a) to c) described above may be output in a combined form.

Information representing an emergency situation according to an embodiment may be at least one of emergency occurrence notification information, a type of emergency vehicle, a moving speed of the emergency vehicle, a moving direction, and a standby time.

For example, when the emergency vehicle 1 is an emergency vehicle, the traffic light management unit 22 confirms that the traffic urgency level of the emergency vehicle 1 is relatively 'high' level from the hospital server (not shown), and accordingly Accordingly, it is possible to generate a control command to output information in the form of a flicker in terms of brightness 'phase', size 'phase', and duration 'phase'.

On the other hand, when the emergency vehicle 1 is a police vehicle, the traffic light management unit 22 confirms that the traffic urgency level of the emergency vehicle 1 is relatively 'medium' level from the crime management server (not shown), and accordingly It is possible to generate a control command so that the size of the police car-shaped icon is 'medium', the number is 'medium', and the output speed is 'medium'.

According to the embodiment, the traffic light management unit 22 adjusts at least one of the volume and duration of the voice information with reference to the information on the degree of traffic urgency and outputs the traffic signal control command together with the display information indicating the emergency situation. can create

For example, when the traffic urgency level is 'high' level, the corresponding volume can be controlled to be output at about 100 decibels for about 5 seconds, and when the traffic urgency level is 'medium' level, the corresponding volume level can be controlled. It can be controlled to output for about 2 seconds at about 50 decibels.

Meanwhile, according to the embodiment, the terminal manager 23 may receive a traffic signal control command from the traffic light manager 22 and control output to the pedestrian terminal 51 .

That is, a traffic signal control command for controlling display information indicating an emergency situation and/or audio information to be output together with walking disabled information can be transmitted through an app of the pedestrian terminal 51 located near the pedestrian traffic light 4.

According to this, in a complicated and noisy road situation, by receiving the information from the pedestrian terminal 51, the pedestrian can clearly determine and respond to an emergency situation, thereby enabling safer traffic system management.

And, according to the first embodiment, there is an advantage in that an emergency situation can be clearly confirmed without being hindered while checking the existing information on walking impossibility.
