Comment	Ah I see, you mean move traffic through Hope Street faster so it leaves less pollution. That doesn't really work because if you facilitate higher traffic volumes (by making transit of the street faster), you just facilitate the same or higher emissions. Individual vehicles may spend less time on the street, but more vehicles spend time on the street overall. Maybe if things go well you reduce net emissions by doing something like that, but it comes with huge detrimental effects on navigation for pedestrians too. Better to keep it a city centre street rather than an expressway-lite, and tackle emissions another way (i.e. through LEZ criteria).
