1. Introduction The purpose of this document is to provide detailed and specific operation description to help the audience understand the feature of the “Purple Umbrella” application and operate it effectively and efficiently.

2. Product overview 2.1. Product Introduction As shown by statistics, more than 50% of the female have experienced street harassment in Australia. Newspapers also suggest that street harassment is a considerable social problem in Melbourne. “Purple Umbrella” committed to providing young women with an easy-to-use and effective mobile website to help them avoid the risk of suffering from street harassment in Melbourne city center, especially at after dark. The main value of “Purple Umbrella” is delivering a carefully curated map which shows the safety index of streets by considering factors that concern women and help them to plan a route. It also allows the user to report any incidents of street harassment and along with that, we have provided a one-click button for dealing with an emergency instance. Moreover, “Purple Umbrella” provides support information to victims of street harassment or sexual violence. Additionally, the website is developed as responsive so that it can run well on both on a personal computer and a mobile device. The underlying support of achieving the above function is a list of datasets from multiple open data platforms. Link of the build: www.purpleumbrella.ml

2.2. Target User The target audience of the Purple Umbrella is young women pedestrians within Melbourne. Such as those who living in Melbourne CBD, who meet friends in the city center at night, female students studying in Melbourne and young female traveling to Melbourne. 2.3. Key Feature The main features of “Purple Umbrella” is

• Visualize data about the location of bars, night clubs, and construction sites • Visualize pre-calculated safety index • Visualize data about real-time pedestrian flow (update every 30 mins) • Visualize the circle user can arrive in 10 minute by walking • Provide navigation and show the shortest route • Allow user to use current location to plan a route • Visualize user selected factors on their route • Allow user to report an incident and select time, address and incident type • Allow user to guarantee an incident reported by others • Visualize different incident on the map with different marker


3

• Show a step-by-step tour to user to explain functions • Sound a noise and/or call police when emergency • Provide information of organizations which may help

2.4. Constrains • Limited by the availability of current open source data sets, the calculation of the

safety index is not accurate enough. Which only take four elements into consideration that street light, security camera, stores, and bars. These limiting factors can affect the credibility of the calculation results.

• Limited by the availability of current open source data sets, the scope of system service only cover the Melbourne city center.

• Limited by time, budget and human resources. The system is not able to provide an alternative route to the user or show any comparison information of two routes.

The recommend developing and changing configuration is:

Ø Processor: 1.8 GHz or faster. (Dual-core or better) Ø RAM: Recommended 4 GB Ø Hard Disk Space: 20-50 GB free space of typical installation

See details about how to set up a development environment in Visual Studio at Appendix A in this document. 4.3. Set up Database In order to set up the database, this instruction is separated into two parts. The first part talks about how to create a database on Microsoft Azure, the second part talks bout how to set a connection string to your build. See details about set up a database on Microsoft Azure at Appendix B in this Document. 4.4. Data Pipeline Architecture

In order to build the data pipeline, this instruction is separated into two parts. The first part talks about how to set up an AWS instance to accommodate wrangling programming code and flask server. The second part mentions how to deploy the wrangling programming code and flask server in this AWS instance. See the step-by-step instruction of launching data pipeline at Appendix C of this document.

5. Security & Privacy 5.1. Installed Security Measure Description

• SSL certification: The current system has install SSL to encrypt the process of data transfer between our web server and users’ browser. So that this secure link ensures that all data passed between the web server and browsers remain private and integral.

The current SSL is installed by using the service provided by Cloudflare.com. In details, the steps of this process can be summarised as:


6

Ø Create an account on Cloudflare Ø Add complete website URL to Cloudflare and waiting for scan Ø Select a free plan once the scan is done Ø Point the name server of Purple Umbrella to Cloudflare, delete the existing

entries, and add the DNS that Cloudflare provided. Ø Go to the ‘Crypto’ page, select ‘Flexible and the rules “always use https”

• Limit user input Use present options instead of text input from users to realize user input. So that the risk of XSS attack is reduced.

In details, for the navigation feature, all input address need to match an address which confirmed to exist. For the report feature, time and report type are selected by user rather than be inputted.

5.2. Security Problem Response Guideline

5.3. Backup & Recovery Guideline Category Issue Recommended backup frequency Database Table “RoadSegment” Seasonally or when data update Database Table “ReportType” Yearly or when data update Database Table “Report” Daily System Overall system Before system updating, function expansion

and/or publishing a new version See step by step guideline about backup an Azure SQL database at https://blogs.msdn.microsoft.com/mast/2013/03/03/different-ways-to-backup-your-windows-azure-sql-database/

Type Problem description Handling & Post hoc measure

Data damage System crash/ disruption, Trojan virus file damage caused data problems

Regular data backup based on the frequency of data update (see detail at Section 5.3 in this document); Doing offsite data backup when necessary.

Data lost

Mis-operation , server is attatcked, system instability, system vulnerabilities, malicious attacks, data deletion, etc.

Strengthen the security settings of the server operating system, security detection of its own code, security settings of the database system

Data leakage The server is illegally invaded; information transmission based on Internet access is leaked.

Security detection of software self-encoding, enhanced security settings of database system, encrypted storage of critical data.

6. Training For end user, using the service provided by “Purple Umbrella” do not require specific training since this application does not need to be installed, and functional operation does not require any expertise and special knowledge. Normal citizen who are familiar with operating mobile and personal computer can use the service provided by “Purple Umbrella” naturally.

7. Future site/drive After publishing the application to Azure app service, it will use purpleumbrella.azurewebsites.net as the domain name by default. This domain name is taking Azure as the main part so that it may lead to the misunderstanding that this application is published by Azure. It is also not user-friendly and not easy to remember. To avoid this misleading domain name, it needs to be mapping to a customized domain name. A domain site is required to register from domain providers. There are few domain providers offering free domain hosting, such as Godaddy.com, Freenom.com, etc. Depends on the rank of domains, the price is charged differently. For the current product, it is using .ml as domain suffix.

8. How to look after the data As mentioned in Section 2.4 above, the pre-calculated safety index is based on four factors namely, stores, bars, street lights and security cameras. All the four data sources are updated annually and the update needs to be done manually. The wrangling code for the data sources has been included in the handover package.

Data Source URL Update Frequency

Cafes and restaurants, with seating capacity

https://data.melbourne.vic.gov.au/Economy/Cafes-and-restaurants-with-seating-capacity/xt2y-tnn9

Annually

Bars and pubs, with patron capacity

https://data.melbourne.vic.gov.au/Economy/Bars-and-pubs-with-patron-capacity/mffi-m9yn

Annually

Feature Lighting (including light type, wattage and location)

https://data.melbourne.vic.gov.au/Assets-Infrastructure/Feature-Lighting-including-light-type-wattage-and-/4j42-79hg

Annually

Safe City cameras https://www.melbourne.vic.gov.au/community/safety-emergency/Pages/safe-city-cameras.aspx

Not Applicable

Apart from the above, we also show pedestrian flow, location of bars, night clubs and construction sites on the navigation map. The pedestrian flow updates every 30 minutes and the code for fetching the data via pipeline from the API has already been included in the package.


8

The construction sites location needs to be updated every quarter. This task is a manual process too. Any new construction sites or old sites whose development is complete needs to be updated on the map. The wrangling code has been included in the package.

Data Source URL Update Frequency

Major development projects (Development Activity Monitor)

https://data.melbourne.vic.gov.au/Property-Planning/Major-development-projects-Development-Activity-Mo/gh7s-qda8

3 months

Finally, the location of various amenities (bars and night clubs, in our case) can be obtained from the below link:- https://overpass-turbo.eu/

The snapshot below shows a simple example of how you can locate bars in Melbourne.

This can be further extended to include other amenities like, cafe or library in Melbourne (or, any other city). The list of amenities that can be viewed for a city can be obtained from the below link:- https://wiki.openstreetmap.org/wiki/Key:amenity

As a final step, the list is exported as GeoJSON (you can also do - GPX, KML, raw OSM). This data can be updated as per user discretion (we suggest doing it annually).

9. How to make future changes For system maintenance and/or secondary development of “Purple Umbrella”, more support

can be accessed from the Maintenance Document of Web Application - Purple Umbrella ,

Which should locate in the same package of this document.

Appendix A: Step-by-step Guideline about Setting Up A Development Environment in Microsoft Visual Studio Step 1: Decompressed the file TP10-Code_The build-Purple Umbrella.zip and get the folder Purple_Umbrella

Step 2: Open the folder Purple_Umbrella

Step 3: Double click the file Purple_Umbrella.sln to open the project


12

Step 4: Now you can view the panel


13

Appendix B: Step-by-step Guideline about Setting Up A Database on Azure Step1: login to your Azure account, and click “Add a resource”, then select “SQL” database on the menu.

Step2: Now you are in the Create SQL Database page, firstly, click “Create new” in the Project Details section ; Secondly, enter your database name in the Database name filed in the Database Details section; then create a new server by clicking the “Create new” button which under the server field; Finally, select a storage plan based on your real need.


14

Step 3: Now you are in your dashboard page, set a connection strings links your project.

Step 4: Paste the connection string to the connectionString part of web.config file which is in the root directory of the build.


15

Appendix C: Step-by-step Guideline about Building A Data Pipeline In order to build the data pipeline, this instruction is separated into two parts. The first part talks about how to set up an AWS instance to accommodate wrangling programming code and flask server. The second part mentions how to deploy the wrangling programming code and flask server in this AWS instance. l PART 1: How to set up the AWS instance Since the data pipeline architecture is independent from the frontend and backend of the website, it is necessary to set up a server for this data pipeline architecture. In our product, we employ the data pipeline on AWS cloud service. The detailed instruction is described below. Step 1: Create an AWS account

Step 2: Open the EC2 dashboard


16

Step 3: Click Launch Instance

Step 4: Choose an Amazon Machine Image (AMI) Since our data pipeline is operated on an Ubuntu system, you have to choose Ubuntu Server 14.04 LTS (HVM), SSD Volume Type


17

Step 5: Choose an instance Type

Step 6: Configure Instance Details


18

Step 7: Add Storage: Since this data pipeline does not need a huge storage space, you can use the default setting.

Step 8: Add Tags: Under the Key section, please enter “Name”. Under the Value section, please enter “Data Pipeline”


19

Step 9: Configure Security Group This step relates to who can access to this server. Here, please set two types of connect method. The first one is SSH. This allow you to use putty (in Window system) or SSH command (in Linux system) to connect to this server and set up the environment for the data pipeline. Another one is Custom TCP rule. Since you only allow your website server to access this server and retrieve the data, please set up the IP address of your website server (as the picture describes).

Step 10: Review and Launch


20

Step 11: Create a key pair for this server

Step 12: use PuttyGen to generate the login key In this part, you have to open Putty Gen, load the .perm file, and create the key for log in the server.


21

Step 13: use Putty to access to your server In this part, please type your AWS EC2 Public DNS in the host column, and also choose the key you create in the previous step to log in the system.


22

Step 14: Log in your server

l PART 2: How to deploy the wrangling code and flask server Due to the reason that the data pipeline is written by Python 3, you have to install the python 3 package so that you can properly run the program. On the other hand, you also need to install the flask to make the rest API. After you install this two packages, you can run the python code (“ped_sensor_python.py” and “flaskapp.py”) we provide for you. Then, you need to use Crontab to have some settings so that you can access to the government API to get CSV file every 30 mins. Step 1: Install the python3

Step 2: install the flask


23

Step 3: put ped_sensor_python.py and flaskapp.py into this system

Step 4: Run Crontab

Step 4: Crontab setting


24

Step 5: start flask server

Congratulation, now you can operate the data pipeline on your AWS server. If you encounter problem, please check the instruction again and make sure you follow all the steps one by one.

Appendix D: Documented Testing Details Usability Testing Given Agile is the underlying philosophy of the development of “Purple Umbrella”, the usability of the system has tested in every iteration. The details are below:

• Iteration 1 Test date: 8 April 2019 User role: Real end user Test device: PC-Google Chrome & Mobile-Safari Test strategy: user test the website without any instruction Link of Iteration 1 system: www.purpleumbrella.ml/iteration1 Test Video: http://bit.ly/Utest-Iteration1-TP10 Test Result:

No. Category Function point Problem Description /Feedback Problem

Solved?

1 UI Layout The layout is not good especially on mobile, When user want to change the preference, they cannot see the map

YES

2 UI Slider Bar The slider bar only have 2 or 3 stops, so it is not a real “slide” operation.

Function deleted

3 Function Safety Index Display

The safety point can be aggregated, but the map only show the count of how many point here rather than the average point. which is useless to user.

Function deleted

• Iteration 2

Test date: 29 April 2019 User role: Real end user Test device: PC, Google Chrome Test strategy: user test the website without any instruction Link of Iteration 2 system: www.purpleumbrella.ml/iteration2 Test Video: http://bit.ly/UTest-1-Iteration2-TP10 http://bit.ly/UTest-1-Iteration2-TP10 Test Result:


Solved?

1 UI Set preference

The heading is too large, and the checkbox is too small.

Function deleted


26

3 Function Navigation Bar of the webpage

When user click the “home” from the navigation bar, it seems to do not response. Then user can know, it is because of I already on the homepage. But, if user can see a system response, it will be better.

YES

3 Function Set preference

After user click the “confirm” button from the dropdown menu, the menu is still here and what is not expected. Again, when user click somewhere else on the screen, it will not disappear until user click the “Settings” button again.

Function deleted

4 Function Set preference

After user save my preference, the view of the map seems to do not change

Function deleted

5 Function Navigation

When user’s address is out of the range of Melbourne CBD, the safety navigation seems useless. If the address is not in the service scope, the system should give an immediate feedback.

YES

6 Function Navigation User don’t understand what the “draw my route” function stand for. Also, the icon of this function is not familiar in my mind.

Function deleted


When user draw my routes and click the point user want to involve with my route, the remark dialog will automate appear, and it is quite confusing.

Function deleted

8 Function Remarks When user submit my remark, user cannot have a look with that.

Function deleted

9 Function Remark

When user submit my remark, user can know it submits successfully, but I cannot have a review in an easy way. In other words, user must click that part of the street again to see the review and most of the street section is look the same so that it quite confusing.

Function deleted

10 Function Remark If user submit a wrong remark, user cannot cancel it.

Function deleted

• Iteration 3

Test date: 16 May 2019 User role: Real end user Test device: Mobiel & PC, Google Chrome Test strategy: user test the website without any instruction Link of Iteration 3 system: www.purpleumbrella.ml/iteration3

1 UI Factor visualization

When Click the “pedestrian” button, user cannot understand what the bubble mean. Especially the size and color.

YES

2 UI Buttons design

When open the website, user have no idea about what should she do, there are a lot of buttons and seems not consistent. Actually, user don’t know the sequence of clicking those buttons.

YES

3 UI View of the map

The first view of the map real confused user. There are a lot of information on the map, a lot of icons. After user notice the filter menu on right bottom then user can understand she can cancel to view those icons.

YES

4 UI Safety Index User don’t understand what it stand for, and there seems no explanation. YES

5 Usability
