In a general sense we think that the widened carriageway on Mitcham Road is likely to attract more traffic. In making this finding we realise that we are taking a view different apparently from what VicRoads says to be derived from their modelling exercises. Nevertheless, the most recent traffic count showing 29,000 vehicles per day using this section of Mitcham Road, being higher than the projected 24,000 upon which the Council's expert witnesses worked until the further traffic count was brought to light, shows that even the most expert computer driven projections are guesses, albeit educated ones. Future traffic levels are a matter of opinion, not a matter of fact. On balance, the advantages of improved access deriving from the execution of these works are offset by the likely increase in traffic volumes and the intrinsically more complex and difficult manoeuvres entailed in right turning egress from the properties. Ultimately the further Eastern Freeway extension is neither here nor there for these purposes. It is not contingent upon this road widening much less upon the levy of the special charge. If it goes ahead or when it goes ahead, if one takes a more sanguine view, these residents will secure a substantial reduction in traffic past their doorstep. This will occur whether Mitcham Road itself is widened or not. One might think that the reduction of traffic would be even more dramatic if the conditions on Mitcham Road remain as they are now. Vehicles would be more likely to seek out an alternative route.
