The sensitivity analysis is a means for extracting the cause and effect relationship between inputs and outputs in the network model. The paper presents how to find a set of equilibrium path flow pattern by applying the path-based Newton method to deterministic user equilibrium (UE). The solution of path flows becomes candidate flow patterns, from which we can abstract extreme points specially used for sensitivity analysis, by using a linear programming. The numerical example shows that plural extreme patterns exist for sensitivity calculation, but the sensitivity of link flow to the input variables is still unique.
