traci.vehicle.getLaneChangeState / getLaneChangeStatePretty returns whether a change in a given direction is unsafe: - "overlapping" means that a change would directly cause a collision - "blocked" indicates that the change would violate safe gaps so it could cause a collision in subsequent steps
you can also compute these gaps directly with vehicle.getSecureGap For speed changes, you can use getFollowSpeed to compute the maximum speed which is considered "safe" by the current carFollowModel.
