We saw many events, and videos on the news where overcrowding was an issue and people got hurt. This is a main socio economic issue that causes problems at sporting events, at your job, and even your local grocery store! We wanted to combat this issue by rolling out an app that tracks an accurate estimate of the crowd in the location.
What it does
As we mentioned earlier, our main issue is the socio economic problem of overcrowding. After comprehensive research, our solution was to create an app that controls the amount of people in one location. Our app tracks the amount of people in a location and compares it with the max occupancy of a building. If the amount of people is greater than the max occupancy, then everyone gets notified that it is unsafe. People who are planning to go somewhere, the mall for example, would search up the mall on the website. It will tell them the amount of people at the mall, if it is over the limit, they are advised not to go.
How we built it
Challenges we ran into
We ran into many challenges during the development of service. One challenge that we ran into was regarding the reverse geocoding, it was difficult to find a Flutter compatible API that supported the recent null safety protocol update. But we were able to find a geocoding API on the Flutter plugin marketplace after extensive searching. For the website, some issues we ran into was the difference in API results. The address for the same location was coming up a bit different, so we did some string splicing in order for them to be equal.
Accomplishments that we're proud of
Some accomplishments we were able to achieve was to be able to use the firebase to connect both the web and app application. Another accomplishment was to be able to update the data in real time. Whenever there was a phone in a location of an overcrowded area, the user would be notified. This is something we are proud of. This helps people because people can look at data and steer away from places with too many people.
What we learned
What we learned was the dangers of having too many crowds in one area. This can be seen because viruses spread through large crowds, there are injuries in large crowds, and it wastes time for every single person in a crowd. We gained more experience using the Maps API, which will help us for future projects.
What's next for Popu-low
For Popu-low we plan to include a new feature where there will be a warning if the limit to how many people in one single area is being approached.When the limit of people is almost reached it will warn people. Another feature we want to add in the future is to use popu-low to connect it with smart city portals as the city’s can manage the population and it will improve safety. This feature will also help this platform grow as data can be much more accurate. The government would possess data such as max occupancies for each building which would give us more accurate data than the max occupancy data we have right now.
