A roadway lane of a host vehicle is determined based on a sound from an impact between a tire of the host vehicle and a set of protrusions in a roadway. A communication is received from a target vehicle. The communication identifies a roadway lane of the target vehicle. The roadway lane of the host vehicle is compared to the roadway lane of the target vehicle. A vehicle subsystem is controlled in accordance with the communication based at least in part on whether the roadway lane of the host vehicle is the same as the roadway lane of the target vehicle.

In some embodiments, a directional surface marking maythat provides directional messaging to users based on their direction of travel on a base surface, such as a roadway, walkway, or interior flooring, as non-limiting examples. In some aspects, the directional messaging may comprise different colors, text, or symbols, wherein a user may view different directional messaging on a directional surface marking dependent on direction of travel. In some embodiments, directional surface markings may comprise a profile layer, wherein the profile layer may comprise a plurality of profiles, which may allow for an application of directional messaging.
