SafeStride sources data primarily from Metro PD, through the website opendata.dc.gov. Every night at midnight, crime events from the past day are released to the public to view. SafeStride scrapes this data, and inserts it into our own database. When users are ready to open the application, they will see these recent crimes. They will be able to customize the date range for the crimes that they are interested in, and can additionally use the reporting feature to fill in the map if they feel it is incomplete.

The other primary feature of SafeStride is to provide safe walking directions to a user. Based on their preferences (defined in the settings page), users are given customized walking directions to their destination. Simply by typing in a destination, our Dijkstra's-based algorithm will determine which edges (or streets) are most in-line with the user's preferences, and will return three potential walking routes for the user to choose between. These routes are scored through a combination of (1) preferences, (2) decay over time, and (3) decay over distance. Of the three walking routes provided, one will be optimized for time, one for distance, and one with a combination of the two.

When users are ready to select a given walking route, they can click the "go" button seen in the image above. This will take users to a new screen, where they can see their walking route and additionally access turn-by-turn directions of the walking route. Included in this screen is a plotting of crimes nearby the route that have happened over the past three days. In these areas, users can pay extra attention to their safety.
