I have done on-site research and took 12photos there and timed the door closing time in MTR –about 1 min to 90 seconds
Some of the research were mainly from Google –30 photos.
In my own feeling, I feel sorry for those who got injured in the train especially children and elderly. The reason I choose this topic was because I got injured once in the MTR too.
I think the light indicator idea may be feasible and could help a lot of people. This project was an interesting project that I observed a lot and opened up my perspective and analysis some problems in the MTR.
