Requirements Clarification & Assessment

To effectively answer the question on the distribution of daily trips in NYC, it's crucial to clarify the requirements and assess the available data:

  1. Clarifying Questions:

    • Type of Trips: Are we considering all types of trips (e.g., public transit, taxis, ride-sharing, personal vehicles) or focusing on specific ones?
    • Data Availability: What datasets are available? Are there historical records, real-time data, or both?
    • Geographical Scope: Are we looking at trips within NYC only, or including commutes from neighboring areas?
    • Time Frame: Are we analyzing daily patterns, or is there interest in seasonal or yearly trends?
    • Purpose of Analysis: Is the goal to understand current patterns, forecast future demand, or something else?

  2. Assumptions:

    • Assume the focus is on cab/ride-share trips within NYC.
    • Consider typical weekdays and weekends separately due to differing patterns.
    • Assume data includes timestamps, trip origins, and destinations.

  3. Hypothesis:

    • Weekdays: Higher trip volumes during morning (7-10 AM) and evening (5-8 PM) rush hours.
    • Weekends: Increased trips in the evenings and throughout the night due to leisure activities.

  4. Metrics to Analyze:

    • Number of trips per hour.
    • Average trip duration.
    • Trip start and end locations.
    • Ride request types (e.g., Uber, Lyft, taxi).
