WebAbstract. This study examined spacing characteristics and safety of platooning vehicles on highways. Even at low volume conditions platooning occurred. When time headway was 4 seconds or less the vehicle was considered in platoon. The percentages of platooning vehicles were 61% and 76% when hourly volumes were 269 and 502, respectively.

Webwhere T max is the maximum individual safe time headway, and q is the coefficient that satisfies q > 0. We also can see that, h (I, T i) ≥ T i is an increasing function with respect to I implying that the safe time headway increases whereas the rainfall intensity increases. WebApr 1, 2024 · When headway is less than dynamic safe headway, especially when Δ v n t is negative, the driver must fully adjust the headway to prevent collision. And the intensity of the deceleration depends on the ratio of dynamic safe headway to actual headway. It can be seen that the definition of θ (Eq. (9)) is consistent with the real driving behavior.
