Overview
In this part, I will discuss project summary, introduction to my insights into the problem noted, and objectives.
Methods
Generally, the whole method can be divided up to 5 steps as the figure 5 below: 1) collecting data; 2) selecting trashcan; 3) selecting the optimal route; 4) displaying result to driver; 5) analyzing results, where step 3 and 5 can be further divided up to sub-steps.
In the following, each step is discussed in details seperately.
-
Data collection
Knowing the status of each trashcan is the first step, as it offers us information used to evaluate urgency of each bin.

Route selection
After attaining all possible routes, I used analytical Hierarchy Process to make the decision on the optimal route.

Viewer display
Finally, the optimal route is sent to drivers' phones in the form of a map, stating the order to be picked.

Analysis of results
Several factors with respect to the results are analyzed: overall statistics about driving distance and time, comparison between optimal, average, and worst route with regard to total distance, fuel consumption, and CO2 emission.
- -8200 meters
- -18 liters
- -425 kg/year
