MY first thought - even before noticing which research centre this came 
out of - was that increasing private automobile throughput would simply 
induce more traffic on adjacent streets...

HOW about a large portable L.E.D. sign - similar to ones warning of road 
hazards, temporary speed limit, etc. - which shows current passenger 
throughput? It could be based on average occupancy of private cars and 
buses... one such apparatus could be moved to different locations, would 
look great on TV, etc... there could be a live throughput counter on 
municipal website, local news websites...

YES.
