Methodology

We will be doing our research on an area in Tampines East Zone 2 (the purple region) to identify the connectivity of the given residential blocks to the points of interests.

Objective 1: Identify how accessible the facilities, that are within walking distance and meet the basic needs, to the residents.

1. Using QGIS and residential blocks shapefile, draw a 400 metres buffer radius from each postal codes and identify the facilities that are within the radius. These facilities include schools, bus stops, green space, convenience stores, and places of worship.

2. Conduct site visit at Tampines East Zone 2 where an actual distance will be plotted with use of QGIS mobile application, Map It! While plotting out the actual distance taken to travel to the various facilities identified, areas that are in need of improvements such as areas catered to elderly, uncovered linkways, undeveloped footpath and dimly lighted pathways.
a. Site visits will be conducted during 5pm - 7pm on weekdays, under sunny and rainy conditions, where majority of the mobility of the residents can be observed.
b. The actual distances to various facilities will show the real distance of travelling despite having the facilities being located within the 400 metres buffer radius.

3. Display a heatmap of the travelled lines where the colour of the lines show the time taken to travel by 2 categories of pedestrians - young and old.
a. Young individual: 5.4 km/hour
b. Old individual: 4.6 km/hour

Objective 2: Fine-tune the design of the residential areas to ensure that the points of interests are connected and are well-served to the needs of the residents (based on demographics - elderly and children)

Work Scope

Literature Study

To understand previous studies on walkability in Singapore and in other countries and to understand the types of infrastructures that can be introduced so as to be able to make recommendations to improve the connectivity between residential estates and points of interest.

Software Learning

Learn how to use the QGis software, both on the laptop as well as on the mobile phone (to aid data collection)

Data Collection

We will be collecting data through 2 methods:
1) Going to Tampines to manually collate data with regards to:

Physical infrastructure	Walkways (Both covered and not covered) Traffic lights Pedestrian Crossings Overhead Bridges School Zones Street Lights Staircases Wheelchair-friendly slopes
Other types of data	Undeveloped footpaths

2) Collecting Data from URA with regards to the demographics of each residential block to help us better understand the distribution of people in the area of Tampines that we are analysing on.

3) Onemap:

Points of Interests	Elderly care Tampines North Primary School Dunman Secondary School Market and Grocery Stores Community Centres Parks Bus Stops Fitness Corner and Playground Sport facilities
Residential Blocks	Blk 491A- 491G, Blk 492A to 492D, Blk 493A to 493E, Blk 494A to 494F, Blk 495A to 495F

Data Exploration

Gaining insight from the data collected to understand how walkable residential areas are from the nearby facilities, cleaning and sieving out outliers, anomalies or wrong inputs.

Geospatial Analysis

Using QGIS, for the following: Map out paths that residents may take from their houses to identified points of interest Identify points of interest within 400 metres buffer radius from each residential block Understand the coverage of street lamps to analyse the safety of walking paths at night. Through measuring the radius of coverage and the height of the lamp post, we can understand how the distribution of the lamp post should be placed.
