Spontaneous Accessibility for Event Response

On March 16, two escalator outages essentially knocked out access to a significant node in Seattle's transit network. In a post on Seattle Transit Blog's community blog, I discussed how Spontaneous Accessibility can be used to assign a monetary cost to such an event. Any mitigation or preventative measure is going to have a cost; how can the right one be chosen unless the cost of the precipitating event is known as well?
