Cubic Planar Graph and Its Application to Road Network

In this research article, we present the notion of a cubic planar graph and investigate its related properties. The graphs are more effective than both interval-valued fuzzy as it represents level participation (membership degree) vertices edges in interval form number. Moreover, handles uncertainty vagueness efficiently graph. indicates continuous process, whereas point specific process. We introduce terms multigraph, strong weak edges, degree planarity for graphs. Some fundamental theorems based on these concepts also elaborated. propose idea faces dual results to established. Comparison with existing method shows worth our proposed work.
