Introduction

Singapore has a mature car parking system which the project aims to visualize the car park system currently implemented in Singapore and find insights of what types of car parkings are there and how they are distributed across the country. The information about HDB carparks is obtained from data.gov.sg.

Theme of Interest and Motivation

Being a small country in terms of area but having high number of vehicles, Singapore has a very efficient and effective car parking system. So we are very intrigued with the management of parking in various manners across the country. By this project, we will create different visualizations that will help us develop insights which can explain different patterns of car parking systems in different areas of Singapore.

Design Framework

Data Preparation

1. The data available was quite small and did not have the area codes. As we decided to segregate the car parking based on the areas in Singapore, we processed the addresses of the parking lots and picked out the key areas for each parking. We used the HDB dataset from data.gov.sg to extract the key areas in which the country is divided. Following is the snippet of the python code that was used to do this processing.

1. csv to json

Sunburst visualization to view the percent of HDB car parks across different areas.

Zoomable Sunburst to have a closer look of the parking system.

Tree Graph for visualizing hierarchical structure that explains different types of car parking systems.

Interactive dashboard to view different type of parking systems in different areas.

Discussion

Taking into account the visualizations that we created, we found some interesting insights from those which are mentioned below:

1. Currently Bukit Merah has the maximum number of parking lots. This is based on the assumption that all the HDBs have equal number of parking lots. Bukit Merah has more than 6% of the total number of the HDB parking lots
2. Currently of all the areas Jurong West has the highest number of electronic parking's
3. Marine Parade is the only area with only Electronic Parking system
4. Woodlands has the highest number of coupon parking's
5. SengKang has the highest number of HDBs with multi-storey carparks, which is at 94
6. Gaylang has the highest number of surface carparks, which is at 92
7. Jurong West has the maximum HDBs with free carparkings between 7AM and 10:30PM on Sunday and PH
8. Woodlands has the maximum number of HDBs with car parks for the entire day
9. Woodlands and Bukit Merah have the maximum number of HDBs with Night Carparks
10. Sembwang has the highest share of Night Carparks
