Solving the MRT crunch during peak hours

I have written an email to public transport council regarding a solution to the crowding of mrt during peak hours. Posting here for you ppl to see and just throw questions on its viability.

 

Solution:

Put one extra carriage in the front and the back. This immediately increases the MRT capacity immediately. I know the the carriage platforms are of a standard length. The solution is simple. Simply program the first and last carriage doors not to open. This might inconvenience the passengers if they want to get out. A simple observation is that the bulk of passengers get off at certain areas only during peak hours which is orchard for the north side, bugis from east and tanjong pagar from west. Thus, I do not think ppl will be stuck in the carriages.

 

For return trips, I believe that the bulk of travellers also get off at certain stations. Of course, there might be hiccups but I feel a pilot study can be conducted to check its viability.

 

Cheaper than buying new trains and tracks.

 

What do you al think?

its a good idea.. and we dont need scholars to think of that... :D

 

 

those alight at pioneer/boonlay/pasir ris/tampines shall move in to those cabinet..... as docking station has sufficient space, crater for extended length... why not..

There are plenty of scholars up there but they haven't thought of it yet! Maybe most of them are too military oriented.

Ever heard from some engineer it will slow down the train in term of speed and also the cornering and also the tunnel size is fix they cannot buy a bigger capacity one to drive it. So there the limitation. I may not be correct any one from this field can please enlighten us?

But might coz delay as if pple were to move out from the last carriage.At least u have tried to give suggestion or idea to improve on it.We need more pple like u.Unlike some pple here only knows how to bash yet can't give construtive ideas.

increse frequency. follow Hong Kong MTR. we are totally capable of it.

 

This I believe too. Years back when MRT first started I was so impressed when I saw trains arriving 1.5 minutes apart during peak hours, and the crush was nowhere near current levels.

 

Now they tell us the signalling system cannot support such high frequency, max is 2.5 minutes apart. Hmm...

if add 1 carriage front + back = 2 carriage length.

in addition to the first&last carriage door inconveniences, MRT train computer system might need to be improved/modified/upgraded because travel time is affected in view of train's total length, weight, speed, etc ... it might not a simple imlpementation though

stopping time might be extended for commuter to get off from first&last carriage. waiting time might become worst.

u believe the signalling thing? lol.

 

its just buying time. or and "excuse" to not be able to increase the frequency.

Think is the acceleration and deceleration of MRT that need times ba. (I maybe wrong). Imagine the front train stop at station A and there is another train following closly behind, but the behind train need to stop at certain distance behind the traffic switch indicated ( for safety reasons ) . The behind train stop and wait for the light to turn green and when the light turn green, the train accelerate ( take time to accelerate ) and by the time it took to accelerate and to stop at station A would be certain amount of time. So this is quite ineffective as what the engineer estimate is for peak efficiency of the train without to stop and wait for the front train to move off at the station in front is about 2.5 mins. Anything less than that, the train will get stuck behind waiting and end up the time waste accelerate and decelerate which would cause the waiting time to be even longer. ( Correct me if I am wrong )

 

So now SMRT is trying to solve the switch thing which is how the traffic light signal and also how much distance is safe to stop and can it be further reduce? and etc. Their target is to meet 1.5 mins ? That's my understanding. So now there is still limitations in the MRT track system.

might not be as simple as abc though

 

more people. less crunch, slower time?

 

cannot have everything going your way.

MAYBE last time they manual overide the signalling, anything also can, then got a case of train crashed into another train, then no one dare to do it liao....

safety distance quite likely, i was involved in the mrt crash at clementi station when i am in polytechnic, i was in the mrt train behind while my dad was in the mrt train in front.

 

i remember the train i was in braking hard for quite some time but it still keep moving till it bang the train infront.

 

I remember the panic despite it being a not that serious crash, no deaths although quite a number of injuries, i myself was sent to hospital for facial injury.

Wa thats serious.. Ya I think is the safety distance that is the one that cannot be compromise that's why waiting time cannot be further reduce.. so SMRT is looking at other ways like the switch how to effective toggle the traffic light switch etc..

knowing singaporeans' "pattern', the 2 extra carriage will hardly be occupied, just like on the bus, few people want to move the the rear of the bus, most probably it will become the study area of some students or the smooching corner of some amorous couples

 

if add 1 carriage front + back = 2 carriage length.

in addition to the first&last carriage door inconveniences, MRT train computer system might need to be improved/modified/upgraded because travel time is affected in view of train's total length, weight, speed, etc ... it might not a simple imlpementation though

They wanted to do that for LRT and still studying on the feasibility. read it somewhere on the news

why can't SMRT or garment open up to the public for ideas? then they shortlist the feasible ones and study closer.

 

scholars are not God. They will not have solution to every problem. The brains of 5 million population is better than a group of scholars.

 

The garment is still not opening up to the people of SG
