Query: Urban Attractors: Discovering Patterns in Regions of Attraction in
  Cities   Understanding the dynamics by which urban areas attract visitors is
significant for urban development in cities. In addition, identifying services
that relate to highly attractive districts is useful to make policies regarding
the placement of such places. Thus, we present a framework for classifying
districts in cities by their attractiveness to visitors, and relating Points of
Interests (POIs) types to districts' attraction patterns. We used
Origin-Destination matrices (ODs) mined from cell phone data that capture the
flow of trips between each pair of places in Riyadh, Saudi Arabia. We define
the attraction profile for a place based on three main statistical features:
The amount of visitors a place received, the distribution of distance traveled
by visitors on the road network, and the spatial spread of where visitors come
from. We use a hierarchical clustering algorithm to classify all places in the
city by their features of attraction. We detect three types of Urban Attractors
in Riyadh during the morning period: Global which are significant places in the
city, Downtown which the central business district and Residential attractors.
In addition, we uncover what makes these places different in terms of
attraction patterns. We used a statistical significance testing approach to
rigorously quantify the relationship between Points of Interests (POIs) types
(services) and the 3 patterns of Urban Attractors we detected. The proposed
framework can be used for detecting the attraction patterns given by type of
services related to each pattern. This is a critical piece of information to
inform trip distribution models.
