모든 질문 미리보기8 질문

퀴즈를 풀면 정답과 설명이 나타납니다.

  1. 대중교통 앱은 버스가 실제로 도착할 때를 어떻게 예측하나요?
    • 무작위로 추측해서
    • 운전기사에게 사무실에 전화해 달라고 요청하면
    • 실시간 데이터 없이 인쇄된 일정만 사용
    • 차량의 실시간 GPS 위치를 교통 및 과거 이동 시간과 혼합하여
  2. How does demand-responsive microtransit differ from a service following only a fixed route?
    • It can pool ride requests and plan pickups dynamically within service constraints
    • It has no pickup requests or vehicle constraints
    • It is a fixed subway line with no routing choices
    • It refers only to a miniature model train
  3. 수요 예측은 대중교통 기관의 어떤 문제를 해결하는 데 도움이 됩니까?
    • 버스 색상 결정
    • 서비스를 추가하거나 삭감할 수 있도록 예상되는 승객 수를 파악합니다.
    • 방송국에서 재생되는 음악 선택
    • 버스 로고 디자인
  4. What can transit signal priority do for an approaching bus?
    • Guarantee that the bus never encounters traffic
    • Replace every intersection's safety rules with a ridership forecast
    • Adjust signal timing, such as holding or extending a favorable signal
    • Change only the bus route's printed name
  5. How should an agency assess whether a new bus-arrival predictor improves its passenger information?
    • Compare its forecasts with actual arrivals under representative routes and times
    • Accept every forecast as correct because the model is newer
    • Measure only how attractive the app icon looks
    • Ignore missing or stale source updates during evaluation
  6. What does Mobility as a Service integrate for travelers?
    • Only new highway construction
    • A requirement that all vehicles be fully driverless
    • Only the microphone settings in a journey-planning app
    • Transport options, potentially including planning, booking, and payment across multiple modes
  7. Why should a transit arrival predictor check the timestamp of its latest vehicle-position update?
    • A timestamp guarantees that every predicted arrival is correct
    • Older positions always improve a live estimate
    • A stale location may no longer represent the vehicle's current progress
    • Vehicle positions remain accurate indefinitely without updates
  8. In GTFS realtime, how do VehiclePositions and TripUpdates differ?
    • Both fields are names for the AI model's gradient optimizer
    • VehiclePositions supplies location information; TripUpdates supplies trip progress and predicted stop timing
    • VehiclePositions contains only ticket prices and TripUpdates only route colors
    • Both require a neural network to define their file format
