The area of Luxemburg is 2500km2 and the estimated population is 633k. For comparison: the area of London is ~1500km2 with population of 8m+. Do you think that Luxemburg’s system can be scaled up?
Luxembourg resident here. Free public transport is a game-changer. You don't have to think about it, you just step on the bus, or tram. This also means the bus driver doesn't have to worry about checking tickets. There aren't guards to check if people are jumping over turnstiles, etc. Moving to 'totally free' eliminates all kinds of overhead. There is no reason it couldn't scale. And the question of scaling hides an…
This ignores two elements:
- congestion differs by time of day, and
- capacity is constrained differently by mode
In London:
- it's cheaper to take a bus than to take an underground train, and
- there are ticket types that are only valid after the morning rush hour
Both of these decrease peak congestion on the transport system.
The differential pricing would not push people to private transport, but might push them to buses (whose capacity can more easily be increased) or to postpone their journey to later in the day.
You know what might push people to private transport? Severe congestion on the underground. If you are not fit and aggressive, then trying to get on a Central Line train in the morning might mean waiting for 2-3 full trains to pass before you can get on one.
