indicates the decrease/increase in travel time and cost of the alternative, where and represent travel time and cost, respectively, and and represent the probabilities of the event occurrence. The plus and minus signs indicate that the travel time/cost of the alternative is gain and loss, respectively, relative to the reference point.
