First Claim
1. A method of generating projected vehicle transportation network information for use in traversing a vehicle transportation network, the method comprising:
- 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, the remote vehicle kinematic state information including at least a remote heading angle for the remote vehicle;
identifying host vehicle information for the host vehicle, the host vehicle information including host vehicle geospatial state information and host vehicle kinematic state information for the host vehicle, the host vehicle kinematic state information including at least a host heading angle for the host vehicle;
generating, by a processor in response to instructions stored on a non-transitory computer readable medium, projected vehicle transportation network information representing a portion of the vehicle transportation network based on the remote vehicle information and the host vehicle information, the portion including a curved path having a substantially constant radius determined using the host heading angle for the host vehicle and the remote heading angle for the remote vehicle;
determining an expected host vehicle route for the host vehicle in response to generating the projected vehicle transportation network information representing the curved path; and
traversing, by the host vehicle, the curved path using the expected host vehicle route.

Abstract
A host vehicle receives a remote vehicle message via a wireless electronic communication link. The remote vehicle message includes remote vehicle information indicating remote vehicle geospatial state information and remote vehicle kinematic state information that includes at least a remote heading angle for a remote vehicle. Host vehicle information is identified that includes host vehicle geospatial state information and host vehicle kinematic state information that includes at least a host heading angle for the host vehicle. Projected vehicle transportation network information representing a portion of the vehicle transportation network is generated based on the remote and host vehicle information, the portion including a curved path having a substantially constant radius. An expected host vehicle route for the host vehicle is determined in response to generating the projected vehicle transportation network information representing the curved path, and the host vehicle traverses the curved path using the expected host vehicle route.
