Answers within 0.005 of the expected value are accepted.

Question 3Route A takes 18 minutes riding plus 7 minutes waiting. Route B takes 14 minutes riding plus 16 minutes waiting. How many minutes shorter is A’s complete trip? Enter a whole number.

Enter a number in min.

Answers within 0.5 min of the expected value are accepted.

Question 4A bus route has a reasonable average travel time but occasional severe delays. What should planning add to the average?

The scheduled travel duration published in the timetableThe variation around the typical trip timeThe number of scheduled stops from departure to destinationThe average duration recorded during off-peak departures

Question 5A new bridge joins two parts of a network that previously had no usable connection. What has directly changed?

The length of each preexisting road has been reducedThe cost of each trip has become identical in both districtsThe set of reachable places has become larger through the new linkThe observed traffic has become equal to the bridge’s capacity

Question 6On a diagram, stations are joined by rail segments and arrows show passenger volumes. Which distinction keeps the drawing clear?

Stations are nodes, segments are links, and volumes are flowsStations are flows, segments are nodes, and volumes are modesStations are modes, segments are flows, and volumes are linksStations are links, segments are modes, and volumes are nodes

Question 7For perishable goods, a shipper chooses between a cheap but unreliable service and a costlier dependable one. Which comparison accounts for the full delivery cost?

The freight charge and the financial consequences of delayThe quoted freight charges and the scheduled travel timesThe network’s link count multiplied by a standard connection chargeThe route distances and a standard charge per kilometer

Question 8Homes sit beside an expressway but far from its entrances. What determines whether the road improves residents’ access?

The shortest geometric gap between a home and the roadThe usable connections from homes to destinationsThe maximum vehicle speed permitted on the expresswayThe total length of road within the housing district

Question 9Following road construction, a city has faster roads, yet people without cars reach fewer essential services. Which measure identifies the problem?

The average speed of buses traveling between their stopsThe total passenger boardings across the city’s bus routesThe maximum passenger capacity of the available bus fleetThe destinations reachable within travelers’ time and cost limits

Question 10Many routes pass through one transfer terminal. Which consequence follows from that layout?

A separate direct link connects each pair of outer terminalsTransfers disappear because the routes share one central stopDisruption at the central interchange affects connecting tripsA single hub gives more independent paths than a dense grid
