wheelchair.friendly?

we have ramps, slopes, lifts for e wheelchair bound residents but how effective are these?

while on e way home this morning, i saw this scene..

a wheelchair bound resident was going up e slope that was leading to e lrt station.. he had difficulties.. he wheeled himself once but e moment he let go of e wheel, he rolled down.. n at that very moment, he had to grab hold of e railing to prevent him from starting from square one.. n w his right hand holding on to e railing, his left hand tried w all his might to wheel himself up but wasn't quite successful..

at that point of time, i stepped in to help.. but not without first asking him if he needed some.. he gladly accepted my help n i helped him w that slope.. he was grateful n at e back of my head, i was thinking hw long would he actually take if nobody were to help him?

it's not easy to wheel oneself up a slope single-handedly.. e art of wheeling oneself requires e hands to leave e wheel for that split second and push again.. n although it's a split second, it equates to e wheel rolling back.. or is e problem w e slope? that, it is too steep? or e direction? that particular slope was like a u-turn.. was e distance too long for e wheelchair-bound resident to cope? or is e issue w e wheelchair? not having some anti-rolling system? hahaha~

how can we improve on this? i wonder..
