The Dijkstra’s algorithm [1] is applied on many real world network problems like mobile routing, road maps, railway networks, etc,. There are many techniques available to speedup the algorithm while guaranteeing the optimality of the solution. The main focus of this work is to implement the combined speedup technique which is based on containers and arc flags(COCA). The technique is experimented with two different types of LEDA generated graphs namely random graphs, planar graphs and road networks. The performance metric speedup was measured with respect to runtime of the technique and vertex visited during shortest path computation. The COCA technique proves to give best results in planar graphs. Road networks can be effectively processed with shortest path containers
