Test your understanding of transport impact with 5 practice questions.

Practice Questions

Question 1

Using an exponential decay accessibility model $A=\sum_j O_j e^{-\beta t_j}$ with $\beta=0.1\,\mathrm{min}^{-1}$, $O_1=100$ jobs at $t_1=15$ min and $O_2=200$ jobs at $t_2=25$ min, what is the accessibility $A$?

Question 2

In a hedonic pricing model $\ln P=\alpha+0.08\ln\mathrm{Acc}+\dots$, what approximate percentage change in property price corresponds to a 15% increase in accessibility?

Question 3

For a transit network with $v=8$ nodes and $e=12$ edges, what is the beta-index $\beta=e/v$?

Question 4

A dedicated bus lane project costs \1{,}500{,}000 and yields annual travel time savings worth 20{,}000 hours at \$25 per hour. Ignoring discounting and residual values over a 7-year appraisal, what is the benefit–cost ratio (BCR)?

Question 5

If a transit improvement saves each commuter 10 minutes per trip, with 30{,}000 one-way trips per day, and the value of time is \$15 per hour, what is the total daily time savings benefit?
