More than 11,200 people pass through the station - Melbourne’s seventh busiest - each day, according to Metlink Melbourne’s most recent passenger survey.http://stonnington-leader.whereilive.com.au/news/story/station-frustration-in-south-yarra/
[PTUA spokesperson Kerryn] Wilmot said the station’s Toorak Rd entrance needed to be re-designed and a second entrance built at the northern end of the station to improve pedestrian flow.
She said the tram stop opposite the station needed to be integrated with the station as poorly programmed traffic lights meant commuters either missed their tram or made a dangerous dash across the road.
Presumably, the trams could be fixed by moving the tram stops to the other side of the crossing and altering the lights to give trams a green light and pedestrians a green once the tram had passed.
As to how the crowding could be addressed, there is limited space to expand the Toorak Road exit and uncertainty as to how many would use a northern concourse / exit.
A lot of the people exiting the station during the morning peak will be changing for trams to Domain Interchange. Others will be going to Toorak Road or Chapel Street North.
Assuming that a new concourse at the north end of the platform were built and it did not extend through to Darling Street, the passengers who used it would be exiting to the eastern side for places like Melbourne Boys High School, the Cremorne Bridge or South Yarra's "Forrest Hill Precinct" (an area that recently attracted controversy when council approved a building there with 64 bicycle parks but no car parks because the area was well-served by public transport, but suffering traffic congestion ie had only a couple of narrow roads feeding Toorak Road). People who wanted to go east along Toorak Road could also sneak along Claremont Road to Toorak Road if they alighted at the northern end of the train.
