Many would agree that safety should never take a backseat, so let’s examine why the safety factor of elevated rail is immeasurably better than at-grade systems – a continuation of yesterday’s comparison of the two approaches.
Reliability Completes It
So the fourth leg of the “Desirable Transit Square” is reliability – having transit arrive and depart when it’s supposed to. Commuters on a system with a reputation for reliability can routinely schedule their trips based on a timetable. They’ll know before they even get on the train when it will arrive at their destination.
Grade-separated transit is the only transportation mode that allows you to do that. Buses and cars obviously don’t, since they’re subject to the surface congestion that elevated rail completely avoids.
Bring the four characteristics together in a system and you’ll have a fast, frequent, reliable and safe way to travel through town that’s virtually assured of success, especially when cost and convenience are part of the decision to ride.
