Based on the city's Transport and Traffic Improvement Plan 2004-2014, the city's daytime population is estimated to be 3.7 million during weekdays, owing to the large number of people who come to work, do business, or shop [REF].
The daily influx of people into the city provides the skilled labor force that allows Makati to handle the service requirements of domestic as well as international transactions; it also serves as the base of a large consumer market that fuels the retail and service trade in the city [REF].
