Thx, Dan,
Nice works.
However, really curious on the details how ESRI implements Djkstra's Algorithm in Network Analyst for efficiency…Can you instruct?
Govinda,
For network data analysis with ArcGIS 10.x, it would be nice also to do hands-on with 'The data that the ArcGIS Network Analyst tutorial exercises and workflows reference' at http://www.arcgis.com/home/item.html?id=d6bd91b2fddc483b8ccbc66942db84cb ...which offer deep insight on how ESRI Network Analyst tackles graph data for routing questions.
After those exercises, you can build a 'network dataset' and perform analyses on a 'network dataset' (rather than SHP file) with ESRI NA, including OD cost matrix.
By the way, please also refer to the 'Engineering Fast Route Planning Algorithms' (attachment)...
