Written by Jerry Ratzlaff on . Posted in Civil Engineering

Passing distance, abbreviated as $$d_2$$, is the distance traveled by the passing vehicle while in the left lane.

Distance While Passing Vehicle Occupies Left Lane formulas

 $$\large{ d_2 = \frac{ \bar {u} \; t_2 }{ 0.68 } }$$ $$\large{ d_2 = 1.47 \; \bar {u} \; t_2 }$$

Where:

 Units English Metric $$\large{ d_2 }$$ = distance while passing vehicle occupies left lane $$\large{ft}$$ $$\large{m}$$ $$\large{ \bar {u} }$$ = average speed of passing vehicle $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{sec}}$$ $$\large{ t_2 }$$ = time the passing vehicle occupies the left lane $$\large{sec}$$ $$\large{s}$$
