calculating shortest path using different methods

Dear all,

I am trying to get the shortest path in behave of (time - distance) between a set of 200 nodes.

I have two method to find it:

  1. using shortest path method ( calculated between two points - it will take a lot of time).
  2. using OD matrix method ( very fast).

So i have created a small network (6 nodes) to check the results of each method.

  • For distance: the results from two methods are the same.
  • For Time: there are differences between the two methods. Also, there are differences when i change between the origin and destination for the both methods (for example: time from node 2 to node 3 & from node 3 to node 2).

 

I hope any one can tell me about the reasons of different results.

 

*attached  the results of the simple network.
