Empirical Evidence and Scenario Testing

Generation Y and Travel behavior: an international analysis of drivers of travel behavior and the impact of personal attitudes and environmental concerns among young generations of college and university students.

PI: Circella
Funder:

The aim of this project is to study travel behavior of young travelers, with age between 18 and 35. The main target of this study is composed by university students, either undergrad or graduate students. They are an important segment of the population: they are potential buyers of vehicles and will have a growing purchasing power in future years, and will contribute to create new households and influence travel patterns in future years. This study wants to investigate what drivers of travel behavior motivate younger generations to adopt specific travel patterns and levels of car ownership, and what the impact of personal attitudes, influence of peers and environmental concerns have on their decision to purchase new vehicles and choose specific mobility patterns, with particular attention on developing countries (India, Iran, Egypt and China) and perhaps some OECD countries (selected EU countries and probably Eastern European countries with transitioning economies).

Transportation Futures for Deep Greenhouse Gas Reductions: Synergistic Interactions of New Transportation Technologies and Services with Land Use, Transit, and Auto Pricing Policies (Year Two)

PI: Rodier
Funder: Mineta Transportation Institute

The goal of this project is to illustrate and understand (1) how new transportation technologies (i.e., dynamic ridesharing and electric vehicles) may have synergistic interactions with land use, transit, and auto pricing policies; (2) what the magnitude of those interactions might be with respect to vehicle miles traveled (VMT) and/or greenhouse gas (GHG) reductions; and (3) how to take advantage of emerging data and modeling tools to conduct similar analyses for other emerging technologies.

Transportation Futures-Year 1

PI: Rodier
Funder: Mineta Transportation Institute

Our objective is to determine what alternative scenarios will be most likely to achieve the major reductions in GHGs that are needed by 2050. We will base our analysis on an examination of existing policy and regulations covering vehicles and fuels, and supplement this with an analysis of how land use change and transit can contribute to GHG reductions. We will also include demand management options that have the potential to provide some additional reductions. We will also include an examination of intercity and freight transportation.

Non-Motorized Travel: Analysis of the National Household Travel Survey California Add-On Data

PI: Susan Handy
Funder: Caltrans

The objective of this project is to improve our understanding of non-motorized travel in California
and the factors that influence that travel. To achieve this objective, the research team will
analyze data from the National Household Travel Survey (NHTS), focusing on the California
Add-on data. Descriptive results will show who is walking and bicycling, how much, and for
what purposes. Modeling results will identify key factors associated with walking and bicycling,
including environmental characteristics and individual characteristics. The results will help
practitioners in their efforts to develop effective policies to increase non-motorized travel. The results of the project will be useful in estimating the effects of proposed bicycle and pedestrian projects on VMT and greenhouse gas emissions. The results will contribute to the development of General Plans, local Bicycle and Pedestrian Plans, and Regional Transportation Plans. The project will help to advance the goals of the California Blueprint for Bicycling and Walking and to further the implementation of the state’s Strategic Highway Safety Plan, and they will help Caltrans and the state’s MPOs in meeting the requirements of the new national policy on bicycle and pedestrian accommodation as well as recent California law requiring Complete Streets implementation.

SB 375 Empirical Literature Review

PI: Susan Handy
Funder: California Air Resources Board
Website: http://arb.ca.gov/cc/sb375/policies/policies.htm

Senate Bill 375 (SB 375, Steinberg, Chapter 728, Statutes of 2008) requires the Air Resources Board (ARB) to set greenhouse gas (GHG) emission reduction targets for passenger vehicles for 2020 and 2035 for California’s metropolitan planning organizations (MPO). Each MPO is required to complete a Sustainable Communities Strategy (SCS) as a new component of its long-term Regional Transportation Plan. The statute requires ARB to review each MPO’s SCS and make a determination as to whether or not the SCS, if implemented, would meet the GHG emission reduction targets in 2020 and 2035 for the region. The purpose of this project is to provide ARB staff with a robust set of empirical literature reviews on a wide spectrum of land use and transportation strategies that will help staff evaluate future SCS sensitivity analyses. The reviews also provide MPO staff with data to facilitate the choice of GHG emissions reductions strategies.
