- Repository referred to a final thesis presented to the University of Sao Paulo in order to achieve the Civil Engineering degree.
- The main goal was to develop a tool that could be used to analyze the last mile routing problems in a city
- In the end, a combination of different last-mile statics and street network analysis was made possible, allowing for significant insights to be made on the city's last mile routing problems.
- The project is still going to be developed and maintained even after the thesis is finished, so any contribution is welcome.
The tool was developed in Python and it is able to analyze the last mile routing problems in a city, considering the following aspects:
- Last Mile routing data
- Distance between origin and the destination
- Shortest driving path by Google Maps API and OpenStreetMap API
- euclidean distance by Haversine formula;
- Characterization of different routes
- Center of gravity
- Enclosing polygons
- Percentage of rejected deliveries, and failed attempts
- Integration with Amazon Last Mile Routing data from public s3 bucket
- Distance between origin and the destination
- Street networks geometry:
- Street Network density statistics for different neighborhoods:
- Node density, edge density, self-loop proportion
- Street total length, average street length
- etc.
- Street Network connectivity and orientation statistics for different neighborhoods:
- Node degree
- Polar plots of street orientation
- Street Network density statistics for different neighborhoods:
First you need to certify that you have Python 3.9 installed.
Then you can install the package using pip:
pip install git+https://github.com/Gui-FernandesBR/Last-Mile-Routing-Analyzer/lmr_analyzer.git
The package will automatically install the dependencies listed at requirements.txt file.
Here are some of the examples that you can run to get started with the package:
-
- Main example notebook with all the features of lmr_analyzer package.
-
The documentation is still under development, please be patient. You can check the current docstring of each method and class individually.
The repository is organized as follows:
