If “enforce absolute braking distance” is on, brick wall stop distance is guaranteed. See Vissim manual [48] for detailed description. Default values for Wiedemann99 following model in Vissim (conventional vehicles). If the followed vehicle is a conventional one, the follower maintains 0.9 s spacing time.
