Route analysis - Shortest path


Solving a route analysis can mean finding the quickest, shortest, or even the most scenic route, depending on the impedance you choose to solve for. If the impedance is time, then the best route is the quickest route. Here we are going to perform Shortest Path route analysis. 


1. Open ArcCatalog - Select your road network - Right click - select New Network Dataset


2. Name your dataset


3. Select "Yes" for this step

8. Finish creating your dataset


9. Open ArcMap and select your created network dataset


10. If you need to add other features of  your road network to be add to the layer your can select YES otherwise select NO


11. After adding your dataset you have to turn on NETWORK ANALYST tool bar.


12. Then you have to turn on NETWORK ANALYST extension.
