Commercial area―Select a prime commercial area in the city. Using opensource
mapping programs (e.g., Google Maps or wikimapia), data from
reconnaissance surveys and consultation with stakeholders, select approximately
5 kilometers (km) of interconnected road within a radius of 1 km from the main
commercial area or central business district (CBD). It is to be noted that the roads
to be surveyed must have high pedestrian volumes and be interconnected. In
cases where the central area is circular, it may be logical to select the same origin
and destination point that people use to enter and disembark from the CBD.
