Yes, NYCDOT does not do road diets or bus lanes, for example, without performing a traffic analysis. They would have already determined that the roadway can support one less lane under the same conditions. The second bullet also will help a lot "expand commercial loading..." so I am glad they likely acknowledged the problem you mention (which is very bad in many places) of truck activity. Slowly there has been positive movement at DOT to do more curb regulations for commercial loading to try and improve double or even triple parking that is pervasive around the city.
