This article attempts to numerically evaluate longitudinal excess space when a following vehicle starts to accelerate in car-following states. The excess space was defined as the temporal and spatial summation of car-following safety measure which is called PE, computing the severity of front-to-rear-end collision. Some car-following data collected at a test track evaluated and compared the excess space of a passenger car driven by male, female, elderly drivers and of a heavy vehicle. A numerical analysis showed that the excess space of elderly drivers and heavy vehicle were significantly large compared to that of male and female drivers. It was concluded that significant excess space when a vehicle starts to accelerate, can be reduced for alleviating traffic congestion and decreasing harmful exhaust gases.
