Abstract
The metropolitan area can be regarded as a multi-functional structure consisting of plural coordinated urban nucleuses. This study aims to clarify the characteristics of urban nucleuses and a spatiotemporal pattern of human mobility in the Manila metropolitan area. Hourly density of human mobility from 00:00 to 24:00 in the whole study area is quantitatively studied. Urban nucleuses with six types: central city, business city, commuter town, south suburb, north suburb, and subcenter city, are identified. Differences of human mobility owing to different human behaviors or properties are also analyzed in 10 typical areas with different urban functions. Results prove that pattern of human mobility in each area depends on its human social division, population composition, infrastructure condition, and functional structure. This study provides an effective thinking on handling geo-tagged big data supported by MATLAB programming and GIS technology. Moreover, spatiotemporal analysis of human mobility also possesses a meaningful academic value for transport geography.

The metropolitan area can be regarded as a multi-functional structure consisting of plural coordinated urban nucleuses
This study enables us to identify what structures and characteristics of urban nucleuses have and how human mobility is associated with different urban functions, providing insights into revealing the spatiotemporal gaps of human mobility owing to individual attributes
This section attempts to recognize the pattern of urban nucleuses and further reveals the functional structure of a metropolitan area considering two major kinds of daily life activities: commuting and consuming activities, which can be regarded as the most important induced mechanism of human mobility in urban nucleuses
Summary
The metropolitan area can be regarded as a multi-functional structure consisting of plural coordinated urban nucleuses. Urban nucleuses are core areas carrying important functions: administration, business, cultural activities, landscape, etc. They have agglomeration effect on person trip, logistics, information flow, and exert controls over the surrounding areas. Burgess [1] noted that Chicago fit a structure of concentric rings, depicting different urban land usage His concentric zone model suggested that the Central Business District (CBD) was in the middle of the model, and, the city expanded its domination in rings, forming a concentric structure included factory zone; transition zone of mixed residential and commercial uses; working class zone (inner suburb); and, commuter and residential zone with better housing quality (outer city) from inside to outside. The CBD idea originated from the Chicago School in 1924 was challenged and refuted by many contemporary scholars, like
