Description

High Level Description

I want to implement the MOBIL lane change model for my ego agent in SMART, but it requires the nearest neighbors in the target lane. Can one get the states of the surrounding vehicles (SVs) behind our ego vehicle in the neighborhood lane (identify which vehicle is behind our ego vehicle and calculate the distance to our ego vehicle considering the curvature of road), I can just identify which lane the SVs are, and the SVs in front of ego vehicle with the help of waypoints. Thank you very much for your help!

Research direction
Investigate how to access neighbor vehicle states in SMARTS using the observation and ego vehicle's position. Consider road curvature to compute distance behind ego. Look at the SMARTS API for getting vehicles in a given lane.
