Algorithm 3: Whether $n_1$ and $n_2$ satisfy time-space logicality and trajectory similarity

Input: Attributes of vehicle $n_1$. ($n_1$.start_x, $n_1$.start_time, $n_1$.end_x, $n_1$.end_time); Attributes of vehicle $n_2$. ($n_2$.start_x, $n_2$.start_time, $n_2$.end_x, $n_2$.end_time) Output: bool (Whether $n_1$ and $n_2$ satisfy space-time logicality and trajectory similarity)
