9. Modal Split

This chapter elaborates on modal split in travel demand modeling, emphasizing its significance in transport planning and policy making. It discusses factors influencing mode choice, types of modal split models such as trip-end and trip-interchange models, and provides insights into binary and multinomial logit models. The chapter concludes with examples illustrating the application of these concepts in decision-making regarding transportation options.

Sections

Modal Split

This section discusses modal split in travel demand modeling, focusing on mode choice and the factors that influence it.

9 Section Overview

Start current section content and materials

9.1 Overview

This section introduces the concept of modal split in travel demand modeling, highlighting its key components and the significance of mode choice in transportation planning.

9.2 Mode choice

This section discusses the significance of mode choice in transportation planning, highlighting factors influencing the adoption of public versus private transport.

9.3 Factors Influencing the Choice of Mode

This section outlines the factors that influence an individual's choice of transport mode, categorized into trip maker characteristics, journey characteristics, and transport facility characteristics.

9.3.1 Characteristics of the Trip Maker

This section outlines the key characteristics of trip makers that influence their mode of transport choices.

9.3.2 Characteristics of the Journey

This section discusses the factors influencing the choice of transport mode during a journey.

9.3.3 Characteristics of the Transport Facility

This section discusses the critical characteristics of transport facilities influencing mode choice, focusing on both quantitative and qualitative factors.

9.3.3.1 Quantitative Factors

This section discusses the quantitative factors influencing transport mode choice, including travel times, costs, and parking availability.

9.3.3.2 Qualitative Factors

Qualitative factors are significant but less easily measurable aspects influencing mode choice in transport planning.

9.4 Types of Modal Split Models

This section discusses various types of modal split models used to understand and forecast transportation choices.

9.4.1 Trip-End Modal Split Models

Trip-end modal split models estimate mode choice based on personal characteristics and trip details, providing accurate short-term predictions but lacking responsiveness to policy changes.

9.4.2 Trip-Interchange Modal Split Models

Trip-interchange modal split models apply modal choice analysis after the trip distribution stage, allowing for the inclusion of journey characteristics and policy implications.

9.4.3 Aggregate and Disaggregate Models

This section discusses the concepts of aggregate and disaggregate models in modal choice, focusing on the difference between zonal and individual data-based approaches.

9.5 Binary Logit Model

The Binary Logit Model is a foundational model in transportation analysis that determines mode choice between two options based on utility and disutility factors.

9.6 Multinomial Logit Model

The multinomial logit model extends the binary logit model for situations involving multiple transport modes, illustrating how to compute probabilities and trips for various modes using given travel characteristics.

9.7 Summary

This section provides a concise summary of the essential aspects of mode choice in transport planning, emphasizing its significance and various models used.

9.8 Problems

This section presents problems related to modal split in transportation, highlighting the choice between different transport modes and their implications.

Learning Objectives

  • Modal split is a critical concept in transportation planning, impacting policy and efficiency in urban travel.

  • Factors influencing mode choice are categorized into characteristics of the trip maker, journey characteristics, and transport facility characteristics.

  • Both binary and multinomial logit models offer frameworks for understanding and predicting travel behavior related to mode choice.

Key Concepts

Modal Split

The distribution of travel demand across different modes of transport, influenced by various economic, social, and policy factors.

Binary Logit Model

A statistical model used to predict the choices between two modes of transport based on their respective utilities.

Multinomial Logit Model

An extension of the binary logit model that allows for the choice among three or more modes of transport.

Trip-end Modal Split

A modal split model applied immediately after trip generation, focusing on personal characteristics.

Trip-interchange Modal Split

A model that applies modal split post distribution, considering journey characteristics and mode alternatives.
