TravelSafe leverages the google maps API to generate a safest possible route to a destination based on individual reviews, crime statistics, embassy twitter feeds, disease control agencies of the specific country. It also calculates the distance on each generated optional route.

The activity process is as follows;

• The user logs in or register if they haven’t registered.
• The user gives authorisation to the app to use its resources, such as the location, network, sms, optionally Facebook etc.
• If the user does not grant required permissions, TravelSafe exits to the default screen
• otherwise, it prompts for destination location to be enter.
• calls the google maps API with the filled-in location and get all alternative routes to the destination rated by “safety”
• The user then selects a desired alternative route.
• TravelSafe requests the detail information for the selected route and displays it to the user.

This post represents that the group has chosen appropriate economic and social Contextual Factors that directly link to the marking criteria, and are vital to understanding what requirements app design has. This is based on market analysis, evaluation, and previous engineering decisions. There is evidence that research has been chosen intelligently (by reference to literature and analysis) to produce a conclusion of professional quality, leading to a successful product. 

This post additionally represents Engineering and Design decisions. These are based on the Contextual Factors and literature review which the group have tailored the product to incorporate. This means that the activity diagram has considerable research, fluent design and well planned engineering steps to achieve this. This post illustrates how and why the product has been influenced in its design and engineering, and shows how the engineering of this safest route generator app feature will solve problems through a UML diagram. 

In addition, this post illustrates considerable use of media, innovation and creativity. This is apparent through applying Contextual Research, Design steps and engineering guidelines to produce an activity diagram which contributes to the product, summarises what the product does, and provides visualisations that align with the target market. 

Furthermore this post features the use of different types of media evident in the UML diagram.
