1. A method comprising:

  • accessing a plurality of predefined road component models of short road segments with lanes varying by a shape, by a lane count, or by the shape and the lane count;

    receiving map data comprising line segments representing lanes of a physical road junction;

    selecting a subset of the plurality of road component models to characterize the physical road junction by matching the subset of road component models to the line segments represented by the received map data;

    accessing a table for an order for the subset of the plurality of the road component models;

    assembling the subset of the plurality of the plurality of road components in response to the order for the subset of the plurality of the road component models;

    modeling the physical road junction using the selected subset of the plurality of road component models; and

    rendering the model of the physical road junction to generate an image of the junction view from the selected subset of the plurality of road component models.
