IS TRAFFIC ISLAND NEAR BRIGG IN THE BEST SPOT?

When we took the above picture recently from the top of a double-decker bus heading from Brigg to Lincoln it set us thinking whether this traffic island (centre) is in the best spot.
Would it be better moved further along Scawby Road, closer to the Silversides turn-off?
There's a well-used bus stop on the opposite side of the road to the lengthy row of Scawby Road houses and those on the Silversides/River Meadow estate.
But passengers who alight from  No 4 service Hornsby buses then need to cross the A18.
We think the majority of people on foot would prefer to cross the A18 near Silversides Lane.
The current island, pictured, is ideal for folk  on foot heading towards Castlethorpe and Arties Mill, to the right
But we think there's greater need to cross near Silversides.
What do the good people of Scawby Road think?
Closer to  Brigg there is a crossing point provided for pedestrians at the top of the Waters Edge housing estate, from which many people visit North Lincolnshire Council's Ancholme Leisure Centre. So that one is in a good spot.
