Encoding junction information in map data

A processor comprising:

• one or more circuits to:
• identify, in map data of an area, a junction area that corresponds to one or more potential yield scenarios associated with a corresponding geographical area represented by the map data;
• organize one or more paths that traverse through the junction area according to one or more path groups based on directionality of the paths through the junction area;
• organize one or more contentions that influence behavior of objects traveling along the paths according to one or more contention groups based on behavior influenced by the contentions;
• generate one or more direction data structures that respectively associate the one or more path groups with at least one of the one or more contention groups;
• and
• update the map data that corresponds to the junction area with the one or more direction data structures.

A system comprising:

• one or more processing units to:
• organize one or more paths that traverse through a junction area according to one or more path groups based on directionality of the paths through the junction area, the junction area corresponding to one or more potential yield scenarios associated with a geographical area;
• organize one or more contentions that influence behavior of objects traveling along the paths according to one or more contention groups based on path entry points and path exit points with respect to the junction area;
• obtain one or more direction rules, at least one direction rule of the one or more direction rules corresponding to a particular contention group and a particular path group and defining one or more object behaviors that correspond to the particular contention group and the particular path group;
• generate one or more direction data structures that respectively associate two or more of:
• the one or more path groups, the one or more contention groups, and the one or more direction rules;
• and
• update map data that corresponds to the junction area with the one or more direction data structures.
