A* algorithm for network traffic congestion

I want to use A* algorithm for route forecasting purpose. Through A* algorithm, I want to find the shortest route which has less network traffic congestion.

How I can do this through MATLAB?

To implement the A* algorithm for route forecasting with less network traffic congestion in MATLAB R2018a, you can use resources from the MATLAB File Exchange. These links provide implementations and tutorials:

1. https://www.mathworks.com/matlabcentral/fileexchange/52946-a-star-algorithm
2. https://www.mathworks.com/matlabcentral/fileexchange/64978-a-star-search-algorithm
3. https://www.mathworks.com/matlabcentral/fileexchange/26248-a-a-star-search-for-path-planning-tutorial

If you can upgrade to a newer MATLAB version: starting from MATLAB R2023a, there are enhanced features for pathfinding and road network analysis. The guide on choosing path planning algorithms (https://www.mathworks.com/help/releases/R2023a/nav/ug/choose-path-planning-algorithms-for-navigation.html) includes several A* algorithm implementations.

Importing road network data has also become easier, as explained here: https://www.mathworks.com/matlabcentral/answers/1999318-importing-a-road-map-into-the-matlab-for-simulation.
