The jaggies and gaps in roads on the tile boundaries could be solved by 
rendering into a larger canvas (a little bigger all around by a few 
pixels more than the largest feature) and then cropping to the size you 
require.

We can also see that where a major road meets with a minor road, the 
white lines of the minor road run over the major road, so you probably 
want some sort of rendering order to prevent that.
