Written by Jerry Ratzlaff on . Posted in Civil Engineering

sight distance 1Passing 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 \(\large{sec}\) \(\large{s}\)
