Abstract
This letter provides a safety analysis for emergency
braking scenarios involving consecutive vehicles. The vehicles use
adaptive cruise control (ACC) with a constant-distance policy
together with additional vehicle-to-vehicle (V2V) communication
for emergency braking. We provide explicit formulas describing
how the minimum safe inter-vehicle distance (IVD), for avoiding
rear-end collision, can be shortened with the use of decentralized
environmental notification messages (DENMs). More precisely,
those formulas describe the dependency of such IVDs on V2V
communication delay. We further show how these results can be
used to compute probabilities of safe braking in the presence of
packet losses
