    • Project Choice: Selecting a project after weighing relevant factors, including political judgements and site locations.
    • Specification and Construction: Detailing project designs, contractor selection, and transition to operational status.

    Urban Transportation Planning

    • Involves evaluating and selecting transport facilities for current and future land uses.
    • Projects accommodate growing demands from new developments like shopping centers or residential areas.
    • Short-term planning: Focuses on immediate improvements within three years (e.g., traffic signal adjustments).
    • Long-term planning: Structured for five or more years, encompasses significant infrastructure projects (e.g., new highways).

    Establishment of Goals and Objectives

    • Identifies deficiencies and outlines improvements for the transportation system.
    • Goals often include maximizing ridership, revenue, and development while reducing congestion.

    Generation of Alternatives

    • Identifies various options for improvement in the urban transportation planning process.
    • Involves analyzing the impacts of land-use plans and possible combinations of transportation technologies and policies.

    Estimation of Project Cost and Travel Demand

    • Determines the cost of projects alongside forecasts of future traffic flows.
    • The estimation process is complex and requires advanced modeling.

    Four-Step Travel Demand Model

    • Key for predicting future traffic volumes based on decision-making in travel.
    • Involves: Trip Generation, Trip Distribution, Mode Split, and Trip Assignment.

    Trip Generation and Distribution

    • Trip Generation: Predicts total trips in each zone; factors include income, car ownership, and land use.
    • Trip Distribution: Models trips between origin and destination zones, influenced by production and attraction factors.

    Measures of Transportation Demand

    • Freight transportation demands vary based on commodity characteristics, urgency, and chosen mode.
