A little knowledge of pedestrian traffic signal lights

Pedestrian traffic signal lamp is generally two combination lamp, the light emitting unit is 300mm*300mm or 300mm, there are two basic forms:

1 red and green stand pedestrian walking lamp combination, above static reds, following dynamic green people;

2 countdown pedestrian lights module and red and green with a combination of the above for the countdown, the people with red and green;

Pedestrian traffic lights should be installed in the vertical, the signal lamp light color arrangement should be on the red under the green.

Pedestrian traffic signal lamp indication

1 when the green light to allow pedestrians through the crosswalk;

2. The red light, to prohibit pedestrian access to the crosswalk, but has entered the crosswalk can continue through or along the centerline of the road in the stay to wait for;

3. The countdown display: digital green is pedestrian crossing the rest of the time, the numbers of red is pedestrian crossing also need to wait for the time.

Pedestrian traffic signal lamp setting conditions

1 mandatory setting conditions: the party to meet the following at least one condition, must be set pedestrian signal lamp.

A. school near the intersection;

B. where pedestrians can not see the traffic signal lights, such as a one-way street or a T - shaped intersection;

C. when the signal is equipped with the pedestrian phase, the vehicle stop for pedestrians to pass.

2 when the following at least one condition is satisfied, suitable for setting the pedestrian signal lamp:

A. vehicle signal lamp indication information is not clear enough, easy to confuse;

B. pedestrian waiting in the central island;

C. many pedestrians or pedestrians need help to get through.

Pedestrian traffic signal lamp indication

1 no pedestrian signal

If there is no signal control signal at the intersection of the signal control, pedestrians can pass under the green light of the appropriate vehicle signal light.

2 static "traffic" signal

The static traffic indicator indicates that the pedestrian can pass the intersection according to the direction of the signal light.

3 flashing "no line" signal

Flashing forbidden line indicating pedestrians are not allowed to pass, but has entered the pedestrian crosswalk can continue through.

4 static "no line" signal

The static "no line" signal indicates that the pedestrians have ended through the period, and the other direction of the traffic flow is about to pass.

5 symbol:

Allows the use of symbolic signs as a pedestrian indication signal, if a green pedestrian pattern is indicated by "passage", a red hand represents a "forbidden line" ". These symbols have become the world's common pedestrian signal, but some countries do not use such symbols, and the use of white and orange pedestrian patterns.

6 flashes of "pass" signal

Flashing "pass" signal (i.e. green flash) warning pedestrians: there may be a turning vehicle collision with its route. Green flash time for normal pedestrians crossing the required time, the green flash time can guarantee the safety of pedestrians through the streets.

At present, I have a traffic signal lamp control on the green flash time is not expressly provided, the meaning is not the same. Such as the Nanjing green flash time generally refers to 5-8 seconds, the meaning of is also did not enter the pedestrians in crosswalks prohibited by, has entered the pedestrians in crosswalks stepped through. There is a problem with this approach. In fact, if the crosswalk is long, there is no central green letter than with or stop, green flash time fail to protect the safety of pedestrians crossing the street.

7 pedestrian lights under the control of flashing lights

When the vehicle traffic signal lamp is flashing, the pedestrian signal lamp is closed (no signal indication).
