Further research on the BMTC project led us to observing how visually challenged people navigate in the bus stand and generally use the bus system in Bangalore.
#1. Navigating the Bus Stand
I watched 2 blind people trying to find their way to their busses at the bus stand and started to follow them. Since they were together, one of them was leading the way while the other held onto him and followed. I’ll be calling them leader and follower for the rest of this post. Some of my observations are listed below:
1. The leader relied on his stick for navigation.
2. He bumped his head on a tree branch. This was probably because it wasn’t apparent at the level of his stick which was closer to the ground.
3. For going from one platform to another, they used the over bridge. This was interesting as I never thought people would use the over bridge to do this. The blind obviously do this as it is a better alternative than crossing the road because busses keep coming in at reasonable speeds on the roads inside the bus stand.
4. The way to the overbridge is sloping. He knew where the overbridge entrance was able detect once he got onto it as he immediately started searching for the railings on the side.
5. While walking next to the railing, he held onto the railing and kept tapping his stick on the ground once and then to the side on the wall below the railing on his way up.
6. The sloping walkway turns around on the way up, he was able to detect this with his stick before his hand reached the turn on the railing. This is because his walking stick was quite long. After tapping it on the ground, when he tried tapping it on the left (to the wall below the railing), it didn’t hit anything. This made him slow down a bit; once he turned, he picked up speed again.
7. While walking on the overbridge, he was walking away from the railing there.
8. He seemed a lot less confident navigating in the middle of the walkway than he was on the side, near the railing. This seems obvious after I observed it.
9. He seemed to be walking quite straight, I imagine this is a learned skill cuz if I was to walk blind folded, I’d probably deviate to the left or right.
10. After walking a certain distance, the leader came closer to the edge on the left side and started his routine of tapping floor-sidewall, floor-sidewall.
11. This routine helped him detect the exit to the next platform.
12. He skipped the first exit and kept walking ahead.
13. As he went further, he bumped into a couple of people standing next to the sidewall who did not see him coming.
14. Continuing his floor-sidewall routine, he detected the next exit and led the both of them down it.
15. Again as he walked down, he stayed next to the railing and continued his floor-sidewall routine.
16. Once they reaced the bottom after navigating another turn in the way down as before, both of them parted ways.
17. The leader got off the platform right at the begining. He seemed to know that the bus he wanted would come to that platform.
18. The bus was standing at the time, though how he found that it was there is a mystery, since the engine was off.
19. Now he navigated to the door, confirmed with some passengers on board if this was the right bus and then got on and found a seat.
20. The follower though, seemed to be struggling a bit as I found him still trying to get to his bus.
21. He got off the platform once, detecting the edge of the platform with his stick, checked if the bus standing there was the one he wanted; it wasn’t.
22. At this point a lady asked him where he wanted to go and guided him to the right bus on the next platform.
This was a very interesting observation session packed with a lot of data. Now that I think about it, I feel like a fool for not video recording this. My assumption is that the leader was very familliar with the bus stand since he knew where the overbridge was and once he was on it found his way to the appropriate exit and the right bus thereon.
#2. Trying to board a bus at a traffic signal in the city.
On my way back from office one day, I got off midway to change a bus. This was at a traffic signal. Here I found a blind person trying to find a bus to take him to Banshankari (a place in Bangalore)
Below are my observations:
1. He stood by the side of the road and waited for (I assume) the traffic in front of him to stop. Once it did, he seemed to assume that a bus is in front of him.
2. He moved forward and asked if this bus would go to Banshankari. Not getting a response, he moved backward and continued to wait.
3. The reason he didn’t get a response was that the vehicle that had stopped was a truck and he was facing the rear tyre of it.
4. Now again the traffic started to move.
At this point I found a Volvo bus going to my house, and those who know me, know how much I love these busses and how hard they are for me to resist. So I started to run towards the bus. As I ran, I started to feel guilty about leaving the poor guy to fend for himself. So I turned around and went back to help him. Ladies, If you’ve managed to read this far, you realize what a nice guy I am, and yes I am single and looking ;).
5. Getting back to the point. I reached him and asked him where he wanted to go. Then I told him that the bus stop was a little distance away in the backward direction and he said no this whole area is a bus stop. He probably didn’t realize that it was a traffic signal.
6. So I led him to the bus stop by making him hold my arm and moving forward. This, I had read in a publication by the National Association for the Blind is the more appropriate way to lead instead of taking them by hand. (I will try and post their list and the reasons soon)
7. I asked him which bus would take him where he wanted to go and he knew the number.
8. Luckily, the bus came in a short while and I got him onto the bus.
This ended my observation session. But then I was thinking, how does he or any visually challenged person know when the bus reaches their bus stop? My guess is that they rely on the folks next to them to tell them. The great thing about Bangalore busses now is that they have started to have an automated announcement in the bus about what the next stop is. I hope it spreads to all the busses.
An idea I had while watching the guy talk to the rear of the truck was that busses could have a beeper near the door of the bus which starts beeping when the door opens at a stop indicating to blind people that “I am a bus and this is my door”
Anyway, signing off now. This is turning out to be quite an interesting project. We plan to contact the National Association for the Blind soon.
