A large residual development with $150$ single family homes $($i$.$e$.,150$ dwelling units$)$ is

proposed. Use the given pages from the Trip Generation Manual to do the following:

a$.(1$ point$)$ Calculate the number of AM peak hour weekday trips using the average rate.

b$.(1$ point$)$ Calculate the number of AM peak hour weekday trips using the fitted curve

equation.

c$.(1$ point$)$ Based on your answer to part $($b$)$ using the fitted curve equation, estimate the

number of "entering" trips during the AM peak hour on a weekday.

d$.(1$ point$)$ Based on your answer to part $($b$)$ using the fitted curve equation, estimate the

number of "exiting" trips during the AM peak hour on a weekday.

e$.(1$ point$)$ Briefly discuss the difference between your results from parts $($a$)$ and $($b$)$ and

explain which method you prefer based on the given information. Hint: consider the R$-$squared

value and the number of studies.

f$.(1$ point$)$ Calculate the number of PM peak hour trips on a weekday using the average rate.

g$.(1$ point$)$ Calculate the number of PM peak hour trips on a weekday using the fitted curve

equation.

h$.(1$ point$)$ Based on your answer to part $($g$)$ using the fitted curve equation, estimate the

number of "entering" trips during the PM peak hour on a weekday.

i$.(1$ point$)$ Based on your answer to part $($g$)$ using the fitted curve equation, estimate the number

of "exiting" trips during the PM peak hour on a weekday.

j$.(1$ point$)$ Compare your answers for the entering and exiting trips for the AM peak hour $($part

$c$ and part d$)$ with your answers for the entering and exiting trips for the PM peak hour $($part $h$

and part i$).$ Briefly explain the differences.
