Q$2$: For the intersection shown in the image which is currently operating using yield sign on minor approaches, answer the following questions after carefully reading the data

The following data is applicable for this intersection:

$-$ Design vehicle: passenger car

$-$ Level terrain, grade$=\backslash (0\backslash \%\backslash )$

$-12$ ft lanes

$-\backslash (\backslash$mathrm$\{$a$\}/\backslash$mathrm$\{$g$\}=0\mathrm{.}35\backslash )$

$-$ Speed on minor approach: $35$ mph

$-$ Speed on major approach: $40$ mph

$-1$ lane$/$direction for all approaches

$-$ The following crashes occurred during $12-$month period:

o $2$ right angle with severe injuries

o $3$ left turn with slight injuries

$-4$ rear end crashes

Answer the following questions, and show your calculations when needed:

$1.$ What level of control should be checked for this intersection $($i$.$e$.$ level I, and$/$or level II$,$ and$/$or level III$)$

$2.$ Calculate $($dA$-$stop right$)?$

$3.$ Calculate $($dB$,$ act$-$right$)?$

$4.$ Calculate $($dB$,$ act$-$left$)?$

$5.$ Calculate $\backslash (\backslash$mathrm$\{$dB$\},\backslash$mathrm$\{$min$\}\backslash )?$

$6.$ What level of control is violated?

$7.$ What level of control should be checked?

$8.$ What criteria are satisfied under the level of control that should be installed on this intersection? State and discuss
