Project Description

“This is what inequality looks like.” You Yenn Teo’s recent best seller book uncovers the heightened tension on social inequalities in Singapore. It has motivated to use to delve deeper into the current situations of inequality in Singapore. One way to understand the inequality is to examine the accessibility to many key essential facilities for an ordinary Singaporean living in Housing Development Board units. The aspect of accessibility to look into includes the distance to healthcare facilities (General Practitioner Clinics, Polyclinics and Hospitals), transportation infrastructure (MRT and Bus Stops) , schools, pre-school, police stations, and hawker centres for all HDBs in different planning subzones. We hope to develop an accessibility study tool for urban planners to better strategize the development of new facilities for achieving greater equality for an ordinary Singaporean. For instance, how would Land Transport Master Plan 2040 effectively improve the existing accessibilities to transport facilities.

Our team's objective is to analyse and determine how these facilities such as transportation, school and healthcare services would impact the accessibility level around HDB.

Motivation

The government has been finding sustainable ways to tackle the increasing inequality and stratification in Singapore.With constant development and improvement of infrastructure around Singapore, the impact on accessibility has not really been research upon.

Data Sources

Dataset	Description	Data Type	Source(s)
Singapore Regions	To facilitate urban planning, the Urban Redevelopment Authority (URA) divides Singapore into 5 regions, namely Central, West, North, North-East and East Regions.	SHP	Data Source
Singapore Planning Area	Indicative polygon of planning area boundary. To facilitate urban planning, the Urban Redevelopment Authority (URA) divides Singapore into 55 planning areas	SHP	Data Source
Singapore Planning Subzone	Indicative polygon of subzone boundary. The Planning Regions are divided into smaller Planning Areas. Each Planning Area is further divided into smaller subzones which are usually centred around a focal point such as neighbourhood centre or activity node.	SHP	Data Source

Technical Challenge

Tools and Data Architecture

Challenges:

1. Most of the datasets retrieved provided only addresses, not coordinates. Thus, first we had to geocode each point to get the coordinates.

2. Some datasets had CRS WGS84 while some had SVY21. Thus, we had to convert all to SVY21

3. Calculating the distance from each of the 8500 houses to each of the 5000 bus stops was computationally impossible. Thus, we had to use Raster to create a radius around each house and calculate distance from that house to the bus stops which lay within the radius to get the closest bus stop

4. Plotting 8000 points on a map was very cluttered and not insightful. Thus, we provided the user options to select regions/subzones/towns for better plots
