Complete the following exercises:

Time headway data was collected along the northbound direction of a

two$-$lane highway before and after the installation of a passing lane

upstream of the site. The summary of the headways and their frequencies

before and after the installation of the passing lane are provided.

Has the percent time following changed after the installation of the passing

lane?

Has the average time headway been increased?

Measure individual time headways at a specific location near where you

stay$/$work $($say Richland Avenue$)$ that is away from intersection control and

under light flow conditions. Record approximately $200$ to $300$ time

headways to the nearest second and plot in a fashion similar to Figure $2\mathrm{.}2.$

$($Refer to MAY text$)$ for one volume level. Identify patterns and compare

with results shown in Section $2\mathrm{.}1$ of your text.
