Converging path detection
First Claim
1. A method for use in traversing a vehicle transportation network, the method comprising:
- traversing, by a host vehicle, a vehicle transportation network, wherein traversing the vehicle transportation network includes;
receiving, at a host vehicle, from a remote vehicle, via a wireless electronic communication link, a remote vehicle message, the remote vehicle message including remote vehicle information, the remote vehicle information indicating remote vehicle geospatial state information for the remote vehicle and remote vehicle kinematic state information for the remote vehicle,identifying host vehicle information for the host vehicle, the host vehicle information including one or more of host vehicle geospatial state information for the host vehicle, or host vehicle kinematic state information for the host vehicle,determining convergence information indicating whether a remote vehicle expected path for the remote vehicle and a host vehicle expected path for the host vehicle are convergent based on the host vehicle information and the remote vehicle information, wherein determining convergence information includes;
determining an orientation sector corresponding to a geodesic between the host vehicle and the remote vehicle; and
determining relative position information for the host vehicle and the remote vehicle based on the orientation sector, andtraversing a portion of the vehicle transportation network in response to the convergence information.

Abstract
A method and apparatus for use in traversing a vehicle transportation network may include receiving a remote vehicle message including remote vehicle information indicating remote vehicle geospatial state information and remote vehicle kinematic state information, identifying host vehicle information including host vehicle geospatial state information and host vehicle kinematic state information, determining convergence information indicating whether a remote vehicle expected path for the remote vehicle and a host vehicle expected path for the host vehicle are convergent based on the host vehicle information and the remote vehicle information, and traversing a portion of the vehicle transportation network in response to the convergence information. Determining the convergence information may include determining an orientation sector based on a geodesic between the host vehicle and the remote vehicle, and determining relative position information for the host vehicle and the remote vehicle based on the orientation sector.
