Resilience is a Psychological Construct that is predicated of human beings and, in the same way, applies to human beings. As a Construct of Physics and, within it, of the Resistance of Materials, it can be preached and applied, p. For example, to a foundation ... but "a bus service" is neither a human being nor a physical material ... therefore, it cannot be applied from the perspective of Psychology or from those of Physics, for which cannot be evaluated, nor measured, nor determined.

Siddiqa, this is a relevant question to ask as many practitioners and scholars are still interested in factors that could enhance resilience capacity. Whilst resilience is normally attributed to the capability of people to 'bounce back' from adversity or a crisis-like situation, work is still going on in terms of the necessary characteristics. Some of these could include learning and development, operational capability and strategic foresight, dynamism, agility, flexibility and so on. The extent to which a bus service system becomes resilient is mainly dependent on the extent to which the service-users and those who deliver the service develop resilience capability and foresight. You can also have a look at some of my articles on resilience on RG and Google Scholar. Hope this helps for now.

You can discuss about semantics but i think Siddiqa's question is about how public transport can prepare for -,cope with - and recover from disaster situations. It depends of course from he type of disaster and the extension of it. If you want to build a resilient public transport system you have to know which disasters your region is prone to. Than you can try to prepare technically to overcome the expected problems but you also have to prepare your personnel to minimalise absence (figure out which parameters will convince them to continue working in case of an incident).
