Example one
Referring to fig. 1 and 2, the zebra crossing provided by the present embodiment includes a zebra crossing body, an indicator light mechanism, and a control device.
Hereinafter, the above-described components of the zebra crossing will be described in detail.
In an alternative of this embodiment, two ends of the zebra crossing body along the pedestrian passing direction are respectively a start end and an end. The zebra crossing body is generally composed of a plurality of mutually parallel white solid lines printed on a road. The starting end and the terminal end are relative concepts defined according to the passing direction of the pedestrian, as an example, the moving direction of the zebra crossing body is assumed to be the east-west moving direction, when the passing direction of the pedestrian is from east to west, the end of the zebra crossing body located on the east side is the starting end, the end of the zebra crossing body located on the west side is the terminal end, when the passing direction of the pedestrian is from west to east, the end of the zebra crossing body located on the west side is the starting end, and the end of the zebra crossing body located on the east side is the terminal end.
In an alternative of this embodiment, the indicator light mechanism 1 extends from the starting end to the ending end, specifically, the indicator light mechanism 1 may extend from the starting end to the ending end in a continuous manner, and the indicator light mechanism 1 may also extend from the starting end to the ending end in an interval manner.
The indicator mechanism 1 can gradually turn red from the starting end to the ending end, specifically, the indicator mechanism 1 can gradually turn green to red from the starting end to the ending end, or the indicator mechanism 1 can gradually turn dark to red from the starting end to the ending end. The section of the zebra crossing body corresponding to the reddening range of the indicator light mechanism 1 is a dangerous traffic section, if the traffic progress of the pedestrian is between the dangerous traffic section and the terminal end, the traffic progress of the pedestrian is still safe, if the traffic progress of the pedestrian is between the dangerous traffic section and the starting end, the traffic progress of the pedestrian is unsafe, and of course, if the zebra crossing body is already prompted to have the dangerous traffic section, but the pedestrian is still at the starting end and does not step into the dangerous traffic section, the traffic progress of the pedestrian is also unsafe. It will be appreciated that if the indicator light mechanism 1 does not turn red and the signal light indicates green, then the pedestrian may enter the zebra crossing body at the option.
Wherein, pilot lamp mechanism 1 is by green red structure of change to the section of area that the green scope of appearing of zebra stripes body and pilot lamp mechanism 1 corresponds is safe passing section, and then when can show dangerous passing section directly perceivedly, can also show safe passing section directly perceivedly, if the whole line of zebra stripes body all is marked as safe passing section, so the pedestrian can be relieved and get into zebra stripes body.
In the present embodiment, in order to determine whether or not the traffic countdown of the traffic light is sufficient to walk from the start end to the end with reference to the case of the color change of the indicator mechanism 1 in both the pedestrian passing directions through the zebra crossing body, the number of the indicator mechanisms 1 is set to two.
Two pilot lamp mechanisms 1 set up side by side, two pilot lamp mechanisms 1 are first pilot lamp mechanism and second pilot lamp mechanism respectively, first pilot lamp mechanism uses the first end in the both ends of zebra stripes body as the initiating terminal, second pilot lamp mechanism uses the second end in the both ends of zebra stripes body as the initiating terminal, observe from the visual angle of first end to second end, first pilot lamp mechanism is located the right-hand of second pilot lamp mechanism, thereby no matter the pedestrian is from first end to second end current or from second end to first end current, as long as use in two pilot lamp mechanisms one on the right side of being located as the reference judge can.
As an example, assuming that the zebra crossing body runs from east to west, the first indicator light mechanism takes the east end of the zebra crossing body as the starting end, the second indicator light mechanism takes the west end of the zebra crossing body as the starting end, the first indicator light mechanism is located in the north of the second indicator light mechanism, when the pedestrian passes from east to west, the first indicator light mechanism is used as the reference, and when the pedestrian passes from west to east, the second indicator light mechanism is used as the reference.
In the present embodiment, the indicator light mechanism 1 includes an indicator light 10 assembly, a switch assembly, and a mounting base assembly.

The top of the mounting base has a light-transmitting portion so that light emitted from the indicator lamp 10 assembly located inside the mounting base assembly is emitted out of the mounting base assembly through the light-transmitting portion, thereby ensuring visibility of the light emitted from the indicator lamp 10 assembly.
Optionally, the top of the mounting base assembly is flush with the road surface to avoid affecting the flatness of the road surface.
The switch assembly is electrically connected between the control device and the indicator light 10 assembly, so that the control device controls the indicator light 10 assembly to start changing color by changing the on-off state of the switch assembly. Here, "electrically connected" means that the connection is made in a wired or wireless manner so that an electric signal can be transmitted therebetween.

Adjacent mounting bases can be arranged closely to each other, so that the indicator light mechanism 1 can be laid from a starting end to a finishing end in a continuous mode; adjacent mounting bases may be spaced apart so that the indicator light mechanism 1 may be routed from a starting end to a destination end in a spaced apart manner. It should be emphasized here that the installation position of the installation base closest to the starting end may be flush with the edge of the starting end of the zebra crossing body, or may be shifted by a predetermined distance in a direction close to the ending end compared to the edge of the starting end of the zebra crossing body, and the predetermined distance is determined so as not to affect the prompt effectiveness.

Wherein, the indicator lamps 10 can only emit red light, so that each indicator lamp 10 can change from dark to red; alternatively, the indicator lights 10 may emit green and red light, so that each indicator light 10 can change between green and red, that is, all indicator lights 10 are displayed green until the predetermined time arrives, and all indicator lights 10 are changed from green to red in sequence when the predetermined time arrives, so as to achieve the purpose of dynamically changing the indicator light mechanism 1.

In this embodiment, the control switches 12 are time control switches, and the time difference between the trigger times of any two adjacent time control switches is equal, that is, the indicator light mechanism 1 can turn red at a uniform speed, so that pedestrians can capture, analyze and judge the red-turning rhythm of the indicator light mechanism 1, and adjust the pace speed accordingly, thereby reducing the occurrence of the situation that the traffic safe state is changed into the traffic unsafe state due to the midway reduction of the pace speed as much as possible, and further improving the safety of pedestrians passing through the intersection.
