map matching algorithm python

Map matching is a crucial step in many location-based applications, where the goal is to align raw GPS traces with the underlying road network. This tutorial will guide you through the implementation of a simple map matching algorithm in Python using the NetworkX library. The algorithm presented here is a basic example, and more sophisticated approaches exist in the literature.
Make sure you have the following libraries installed:
Let's start by importing the required libraries and creating a basic road network graph using NetworkX.
Replace the edges and weights with your road network data.
Create a set of sample GPS points to simulate a GPS trace.
Implement a simple map matching algorithm using the closest edge to each GPS point.
This basic algorithm simply selects the closest road segment for each GPS point. More advanced algorithms consider additional factors like road topology and historical data.
This tutorial provided a simple example of a map matching algorithm in Python using NetworkX. Depending on your application's requirements, you may need to explore more advanced map matching algorithms and integrate additional data sources.
