Comprehensive Transportation Planning Dimensions

  • Economic

  • Social

  • Environmental


Systematic Evaluation for Sustainability

  • Can we always count on data being there?

  • If we don’t have data then what can be done?


Indicators

TRAVEL

MODEL

Land use

Travel behavior

T

System performance

Why Use Travel Demand Models

  • A relationship between transport system and indicators

    • Access

    • Purpose

    • Frequency

    • Use


Economic, Social, and Environmental Dimensions

  • Where do they come in to this process?

  • For example:

    • Commute speed

    • Land use mix

    • Transport diversity

    • Transport equity


Example

  • Model output = travel times between all points

  • Indicator: Commute speed

  • Indicator: Land use mix

  • Indicator: Transport diversity

  • Indicator: Equity


Introduction to Travel Demand Modeling

  • What is a travel demand model

  • Assignment: Discuss your knowledge

    • Input data

    • Trip generation

    • Trip distribution

    • Mode choice

    • Traffic/trip assignment


Demographic Data

Step 1: Trip Generation

Transportation Network

Step 2: Trip Distribution

Step 3: Mode Choice

Step 4: Trip/ Traffic Assignment

Four Step Travel Demand Model (FSTDM)


Trip Generation Questions

  • How much do people use the transport system?

  • Why do people use the transport system?

  • Where can different types of activities be satisfied?


Trip Distribution Questions

  • Given a location, where do people go to satisfy demand for an activity type?


Mode choice Questions

  • How do people use the transport system?

    • What modes do they choose?

    • How do they react to varying transport service quality?


Trip / Traffic Assignment Questions

  • How do people use the transport system?

    • Given a mode, which route do they choose?

    • Do they satisfy multiple activities in one tour?

    • Which parts of the transport system do they use?

    • How do they react to varying transport service quality?


Demographic Data

  • Autos per household

  • Income level

  • Household size


Network Data

  • Highway network

  • Transit network

  • Graph
