The cartographic wizards at Bostonography break down Greater Boston's streets, roads and avenues (literally): "Streets, Roads, and Avenues seem to account for the vast majority of street names in the immediate Boston area. Streets clearly occupy most of the central cities, while Roads are a bit more prevalent in the suburbs, especially toward the west. Avenues, meanwhile, dominate some small pockets and comprise a few notable long roads, but otherwise are not nearly as popular."
