My answer is: design of the Beijing Metro-Metro Tunnel

Q: What problems do you think Beijing Metro lacks in design? I met: Let me talk about the most impressive design of the subway tunnel door:

First, it is a traffic sign. This design is still user-friendly, with a green light. Otherwise, the Red Cross is similar to the traffic light design that meets people's daily travel habits.

Then there is the exit design of the channel, which is the focus of my speech. This design is terrible and there is no inconvenience for passengers who use bus cards, in and out, you only need to swipe the card. But for many passengers who use a temporary card, this problem often occurs: As far as I have observed, many passengers with temporary cards will habitually send the cards to the plug-in slot when they arrive at the ready exit. However, in many cases, the current pass cannot be inserted, when a passenger finds that the plug-in fails, he looks at it and finds that the plug-in is not available on the display next to him. Then, he looks for the channels next to him and checks their respective display screens one by one, check whether the card can be inserted.

The design of the display screen is bad when the screen is broken. No obvious visual recognition is displayed, whether it is a prompt that the card can be inserted or cannot be inserted. The screen is black and the font is as big as that of the white screen, even the text length is similar. passengers need to stare at each screen until they find the first accessible pass.

Suggestion:
The prompt screen for card insertion should not be placed on the top of the channel door, but on the front of the passenger, and a recognizable sign should be designed so that the passenger can immediately respond as he passes through the distance.

One reality is that the daily passenger flow of the subway is very large, because such an inconspicuous design flaw is enough to greatly increase the number of passengers to stay at the same time. If it can be improved, it not only facilitates passengers, it can also reduce the burden on subway staff.
