Question 1

A bus-lane pilot is intended to increase peak-direction traveler throughput. Before the pilot, a screenline carried 1,200 cars per hour averaging 1.25 occupants and 20 buses per hour averaging 40 passengers. During the pilot, it carries 1,000 cars per hour at the same occupancy and 30 buses per hour averaging 50 passengers. Walking and cycling volumes are unchanged, and all adopted safety, accessibility, and vehicle-delay limits are met. Which finding should govern the pilot decision?

Accepted Answer

Retain the pilot: total car-occupant and bus-passenger throughput increased by 450 people per hour.

Answer

Reverse the pilot: 190 fewer motor vehicles per hour means lower traveler throughput.

Answer

Retain the pilot: the additional 700 bus passengers per hour are also the net gain in corridor traveler throughput.

Answer

Revise the pilot: its car-occupant throughput declined by 200 people per hour.

Question 2

A regional four-step travel model reproduces independently estimated zonal trip productions, zonal trip attractions, and regional mode shares. Its origin-destination table nevertheless sends too many suburban residents to downtown jobs and too few to suburban employment centers when compared with an independent travel survey. Which model stage is failing this validation check?

Accepted Answer

Trip distribution: allocating trips between origin and destination zones.

Answer

Trip generation: estimating how many trips each zone produces and attracts.

Answer

Mode choice: allocating person trips among modes.

Answer

Trip assignment: loading trips onto routes through the transportation network.

Question 3

Two proposed station-area developments have identical residential density, land-use mix, parking prices, and rail service. Each is a quarter-mile from the platform in a straight line. One has a direct, accessible sidewalk connection; the other requires a one-mile walk around a fenced highway interchange. A forecast assigns identical transit shares using density and straight-line station distance. What assumption most needs revision?

Accepted Answer

Transit access cost should reflect the usable walking route, not just straight-line proximity.

Answer

Residential density should be reduced in the second site's model inputs to represent its indirect pedestrian connection.

Answer

Rail in-vehicle travel time should be increased for all station users to account for the second site's access barrier.

Answer

Both sites should retain identical transit access costs because passengers board trains at the same station.

Question 4

A corridor's travel-time dashboard reports the following for comparable weekday periods. Previously, mean travel time was 30 minutes, the 95th-percentile time was 45 minutes, and the buffer index was 50%. Now, the corresponding values are 40 minutes, 52 minutes, and 30%. A manager interprets the lower buffer index as evidence that travelers can budget less total time for 95% of trips. Which interpretation is defensible?

Accepted Answer

The proportional buffer has decreased, but the travel time needed to cover 95% of trips has increased.

Answer

Travelers can budget less total time because the buffer index has fallen, despite the higher mean travel time.

Answer

Typical congestion has improved because a smaller percentage buffer means that average travel time has decreased.

Answer

The results are inconsistent because a lower buffer index requires the 95th-percentile travel time to decrease.

Question 5

During a construction inspection, a planner sees wheelchair users entering a live traffic lane because work has blocked the only accessible sidewalk. No protected detour is available. Unrelated work farther along the corridor can continue without affecting pedestrian access. The project manager asks for an immediate recommendation. The planner should recommend that the contractor:

Accepted Answer

Pause the operation blocking access and restore a protected, accessible pedestrian route before that operation resumes.

Answer

Stop all corridor construction until permanent sidewalks are completed on both sides.

Answer

Divert pedestrians to the opposite sidewalk despite its missing curb ramps.

Answer

Use a flagger to guide pedestrians through gaps in live traffic.

Question 6

An employment district is changing from office uses to warehousing and distribution, while its forecast total employment remains unchanged. A modeler proposes retaining the existing commercial-vehicle trip estimate because the number of jobs is unchanged. Before accepting that estimate, the planner should:

Accepted Answer

Disaggregate employment by industry and revise freight-trip assumptions for the changed economic activities.

Answer

Retain total truck trips and change their assigned routes.

Answer

Retain the office truck-trip rate and rescale it using the proposed development's total floor area.

Answer

Classify employees by occupational title rather than their employers' industries when estimating freight generation.

Question 7

Under a highway availability-payment public-private partnership, the private partner finances, builds, and maintains the facility. The public agency collects tolls and owes contractual availability payments regardless of traffic volume, with deductions only for specified performance failures. The facility meets those performance standards, but toll revenue falls below forecast. Under this arrangement, who bears the toll-revenue shortfall?

Accepted Answer

The public agency, because its availability-payment obligations remain due when toll receipts fall.

Answer

The private partner, because raising the project capital transfers traffic-demand risk to that partner.

Answer

The project lenders, because debt financing transfers uncertain toll revenues away from the public sponsor.

Answer

Both partners equally, because public-private delivery divides the project's revenue risk into equal shares.

Question 8

A county's rural mobility study has held open houses in the county seat and received many requests for commuter express service. Residents without cars and residents unable to travel to the meetings were largely absent; local service organizations report unmet trips from outlying communities. Alternatives have not yet been selected. Which change would make the engagement program more responsive to those missing perspectives?

Accepted Answer

Arrange accessible outreach through local service organizations and use the findings to revise the alternatives.

Answer

Repeat the county-seat open house and prioritize its most-requested service.

Answer

Apply demographic weights to the existing open-house comments and treat the result as a countywide preference estimate.

Answer

Select commuter express service now and seek outlying residents' comments when individual stop locations are being finalized.

Question 9

Two mutually exclusive corridor alternatives have already been evaluated against the same no-build baseline in present-value dollars. Alternative A has $8 million in costs and $20 million in benefits. Alternative B has $14 million in costs and $30 million in benefits. Both are affordable, use the same analysis period, and have no material nonmonetized differences. The objective is the greatest monetized net benefit. Which recommendation correctly applies incremental benefit-cost analysis?

Accepted Answer

Select B: the incremental benefit-cost ratio is approximately 1.67, supporting the higher investment.

Answer

Select A: its standalone benefit-cost ratio is higher.

Answer

Select A: upgrading to B has an incremental benefit-cost ratio of 0.60.

Answer

Select B: total benefits divided by additional cost yields an incremental ratio of 5.00.

Question 10

A federally assisted roadway project would use a narrow strip of a significant, publicly owned park and permanently remove its only accessible entrance. The design provides no replacement access. The sponsor proposes a Section 4(f) de minimis impact finding because less than 1% of the park's acreage would be acquired. Which conclusion should guide the environmental review?

Accepted Answer

Loss of usable park access prevents a de minimis finding for the design as proposed.

Answer

The entrance should be excluded from the Section 4(f) assessment because the provision protects recreational acreage rather than access.

Answer

Replacing the acquired acreage elsewhere would, by itself, justify a de minimis finding for the design as proposed.

Answer

The small land take qualifies for a de minimis finding if the project does not require an environmental impact statement.
