Understanding how reliability is valued is important because it provides insight to how aims of policies that aspire to provide better transport options can be more fully integrated with user expectations. In this study we derive a choice model for work commute trips that trades off alternatives based on the most frequent experience that users had on that route and the possibility of late or early arrival if they use a particular route. The idea of reliability is incorporated by how far the expected lateness or early arrival is from the most frequent experience on that route. We find that on route decisions the mode travel time is valued at $7.43 per hour while reduction from the magnitude of average lateness (thereby increasing the reliability of the route) is valued at $6.91 per hour.
