However, this approach conflicts with observation that time spent on travelling rather constant might not be affected by changes. paper aims to define benefits addresses two research questions. First, how will in person transport work out, which factors are affected? Second, good proxy for speed? Based studies spending association between land use, we argue human wealth could main factor changes, than or access. Then speed: negatively correlated prosperity following law diminishing marginal utility, while calculated prove positively correlated. inadequacy explained some shortcomings respect willingness pay used assessing time: people do predict correctly personal gained from decision, they neglect social impacts.
