Lane change aspect ratio and dimensionless path for emergency obstacle avoidance

–This paper focused on the use of the nondimensionalization approach in autonomous collision avoidance, while taking into consideration five functions, namely circular arcs, ramp sinusoidal, and polynomials (quintic, septic, and cubic), for emergency lane-change manoeuvres.The aspect ratio, which...
