Living near Timperley tram stop, it seems that the roads (mainly Park Road, the only useful road to the A56 in this area) are busier than usual, allowing for the reduced schools traffic at this time of year; and I've seen plenty of largely empty buses. Of course more traffic means slower bus journeys, so it's a vicious circle. For able-bodied people, none of the Altrincham line tram stops are far from the A56 with its service 263 buses, so it does seem that improving that would have helped matters.
