Rex comments as foollws,Bicycle sharing systems in university campuses work because the traffic drop-nodes are clearly defined, e.g Library, Lab, Computer Centre, Lecture Theatre etc. There is fair inter node travel so the bicycles will on balance be spread fairly evenly between nodes. This is a pre-requisite for the sharing system to be successful.To apply the bicyle sharing to a satellite town like ang mo kio, it is therefore necessary to first identify optimised drop-nodes. MRT station, yes. But where are the other nodes? the AMK library.. it's not that popular. The AMK park? not many people go there. The food centre? no that's too new the MRT station... The HDB blocks? Yes... but there are so many blocks. It is like a fan-out from the MRT to numerous hdb blocks spread out all over thE place.. how to have a fair sharing system to design the nodes...Perhaps the bicycle sharing system may better work in Orchard Rd. The nodes are quite simple, ION, 313, Plaza Singapura, City Mall. But yuks! we have another problem there, the cylcists will get squashed by the buses and cars.So the problem is not technology or economics i think. We have to find an acceptable nodal-model in a relatively safe environment, to apply it successfully.Actually a bicycle is very cheap, about $60 for a simple bike even with gear (definitely required to go up slope).. this is the best investment, it will give you the freedom to go back to your home doorstep from the target location, it is green, it saves you money, hardly any maintenance.rex
