The terminus: why doesn't the T Zen 5 bus go to the Choisy interchange to ensure connections with the RERC and the Trans-Val-de-Marne (TVM)?

Six terminal variants have been studied to meet the objective of getting as close as possible to the Choisy-le-Roi interchange hub. It was the variant located at Régnier-Marcailloux that was chosen given the technical impossibility of inserting the terminus further south.
