How Vancouver fares in the world of driverless metros?

May 17, 2017

Not so well according to a recent study [1]:

Thought the study seems to present numerous flaws, starting by a lack of common metric to measure the service regularity accross different systems, it tends to comfort some conlusion we have drawn previously in regard of the skytrain system reliability[1].

The study presents this interesting matrice showing the service reliability as a function of the frequency.

…and highlight the fact that a very high frequency system (The Paris subway line 14 has a frequency of one train every ~85s, while the Lille subway has a frequency of one train every ~60s.), requires a very reliable system, something Vancouver could apparently not be able to achieve with its current system [3].
