Moving From Cars To People, Kelly J. Clifton, Kristina M. Currans

Civil and Environmental Engineering Faculty Publications and Presentations

The twenty-page comic includes a dialogue, taking place in various urban settings, between characters Kelly and Kristi who are based on National Institute for Transportation and Communities (NITC) researchers Kelly Clifton of the University of British Columbia and Kristina Currans of the University of Arizona. The two have a long history of collaboration around the data, methods, and processes used to plan for multimodal transportation impacts of new development. This short graphic synopsis is an engaging, approachable way for anyone – no matter their level of expertise in this topic – to learn about their findings.

Key Enhancements To The Wfrc/Mag Four-Step Travel Demand Model, Reid Ewing, Sadegh Sabouri, Keunhyun Park, Torrey Lyons, Guang Tian

TREC Final Reports

In a National Transit Institute course on “Coordinating Land Use and Transportation,” co-taught by Robert Cervero, Uri Avin, and the PI on this project, the analytic tools session began with a hypothetical: assume that all households, jobs, and other trip generators are concentrated in a walkable village rather than segregated by use and spread across a traffic analysis zone in the standard suburban fashion. The instructor then asks: How would the outputs of conventional four-step travel demand models differ between these two future land use scenarios. The answer, to most participants’ surprise, was “Not at all.” Conventional four-step travel demand …

Characterizing The Trip Generation Profiles Of Multifamily Housing, Kelly Clifton, Kristina M. Currans

TREC Final Reports

Cities are increasingly wanting to assess the impacts new development has on all modes in the transportation system. Many communities are requiring site-level transportation impact analysis to examine travel outcomes. The historical focus on developing data and methods exclusively for the automobile, such as the Institute of Transportation Engineers (ITE) Trip Generation Handbook, has left planners with little guidance for these new challenges. This study aims to examine the limitations in the dominant approaches to understand how they may misguide the planning process for multifamily housing development. Specifically, we aim to examine the vehicle and person trip generation rates associated …

Getting To Know The Data: Understanding Assumptions, Sensitivities, Uncertainty, And Being "Conservative" While Using Ite's Trip Generation Data In The Land Development Process, Kristina Marie Currans

PSU Transportation Seminars

Many agencies rely on trip generation estimates to evaluate the transportation impacts of land development in urban and suburban areas alike. Over the past decade, substantial attention has been paid to one national set of guidelines—the Institute of Transportation Engineers (ITE) Trip Generation Handbook (2014) and corresponding Manual (2012)—focusing in particular to improve the use of these data and supplementary methods for urban contexts.

The purpose of this study is to explore the typical data provided in the Handbook, within the context of these new improved state-of-the-art methods. As ITE’s describes, “an example of poor professional judgment is to rely …

Improving Vehicle Trip Generation Estimations For Urban Contexts: A Method Using Household Travel Surveys To Adjust Ite Trip Generation Rates, Kristina Marie Currans

Dissertations and Theses

The purpose of this research is to develop and test a widely available, ready-to-use method for adjusting the Institute of Transportation Engineers (ITE) Trip Generation Handbook vehicle trip generation estimates for urban context using regional household travel survey data. The ITE Handbook has become the predominant method for estimating vehicle trips generated by different land uses or establishment, providing a method for data collection and vehicle trip estimation based on the size of the development (e.g. gross square footage, number of employees, number of dwelling units). These estimates are used in traffic impact analysis to assess the amount of impact …
