1. A method for generating a set of instructions to guide a driver along a route, wherein the route comprises a first node, a second node, a third node, a first road coupled to the first node, a second road coupled between the first node and the second node, and a third road coupled between the second node and the third node, and a fourth road coupled to the third node, and wherein the method comprises the steps of:

  • generating a first instruction operative to guide the driver from the first road, through the first node, and onto the second road;

    generating a second instruction operative to guide the driver from the second road through the second node, and onto third road; and

    combining the first instruction and the second instruction into a combined instruction operative to guide the driver from the first road, through the first node, through the second road, through the second node, and onto the third road wherein, based upon the configuration of the first node and the second node, the first instruction and the second instruction are combined into the combined instruction when the driver would perceive the first node and the second node as a single integrated feature of the route.
