Integrated land use-transportation-emissions models are necessary to rigorously assess the potential of land use and transportation policies to reduce the vehicular emissions contributing to tropospheric ozone and to fine particulate matter. A theoretically- and empirically-grounded model contains these major components: data on economic sectors, population sectors, and intersectoral flows of commodities and labor; a transportation network; sectoral demands for land, predicting both the quantity and location demanded; elastic trip generation; transportation mode choice including non-...

Daily Activity and Multimodal Travel Planner: Phase II Final Report

Kitamura, Ryuichi
Chen, Cynthia
Chen, Jiayu
1999

It is important that our travel be organized in an efficient way. One way to achieve this is to provide travelers with a trip planner that produces efficient travel itineraries for them. It is desired that a trip planner possess the following features in order to be useful: be able to handle multiple destinations, multiple constraints, and multiple modes; and be able to adjust travelers' preferences under different circumstances. These features cannot be found in existing trip planners. The goal is then to develop an "Itinerary Planner" that possesses all of these features. The Itinerary...

The Relationship Between Urban Form and Station Boardings for Bogota’s BRT

Estupiñan, N
Rodriguez, DA
2008

Despite emerging evidence about the association between the built environment and travel behavior, the relationship between bus transit demand and urban form remains largely unexplored. By relying on primary and secondary data analyzed with a geographic information system, this paper examines the built environment characteristics related to stop-level ridership for Bogotá’s successful bus rapid transit system. After accounting experimentally and statistically for the simultaneity between transit supply, transit demand, and the built environment, we find evidence of the importance of...

Space Syntax and Walking in a New Urbanist and Suburban Neighbourhoods

Baran, PK
Rodriguez, DA
Khattak, AJ
2008

Prevailing measures of street design have largely ignored the relational properties between local and global street design as correlates of walking behaviour. This study contributes to understanding relationships between the syntactical properties of street design and walking behaviour by examining whether space syntax measures in New Urbanist and conventional suburban neighbourhoods are associated with the walking patterns of residents in these communities. Relying on geographic information systems, survey data and travel diaries, the study relates control, local integration and global...

A Comparative Case Study on Active Transport To and From School

Fesperman, CE
Evenson, KR
Rodriguez, DA
Salvesen, D
2008

This study investigates active-transport-to-school initiatives through the Active Living by Design Community Action Model framework. The framework outlines five strategies that influence physical activity: preparation, promotion, programs, policies, and physical projects. A comparative case study was conducted to investigate active-transport-to-school initiatives at two North Carolina schools. A group of key stakeholders from each site was interviewed (N = 16), including principals, physical education teachers, public safety officers, city planners, regional transportation planners, city...

Urban Containment Policies and Physical Activity: A time–series Analysis of Metropolitan Areas, 1990–2002

Aytur, SA

Evenson, KR
Catellier, DJ
2008
Urban containment policies attempt to manage the location, character, and timing of growth to support a variety of goals such as compact development, preservation of greenspace, and efficient use of infrastructure. Despite prior research evaluating the effects of urban containment policies on land use, housing, and transportation outcomes, the public health implications of these policies remain unexplored. This ecologic study examines relationships among urban containment policies, state adoption of growth-management legislation, and population levels of leisure and transportation-related...

Neighbourhood Types, Travel and Body Mass: A Study of New Urbanist and Suburban Neighbourhoods in the US

Brown, AL
Khattak, AJ
Rodriguez, DA
2008

Using an ecological framework, this paper examines the body mass index (BMI), physical activity and travel behaviour of household heads in a US new urbanist neighbourhood relative to household heads of comparable conventional suburban US neighbourhoods. Using a quasi-experimental design, a new urbanist neighbourhood and five conventional suburban neighbourhoods were matched on age of development, assessed property values and regional accessibility. Self-reported height, weight, physical activity and travel behaviours were obtained from the household heads in each neighbourhood type....

Recherche Originale: Une Etude de cas Comparative sur le Transport Actif Concernant les Allers-retours à L'école

Fesperman, CE
MRP, KRE
Rodriguez, DA
Salvesen, D
2008

Cette étude examine les initiatives de transport actif à l'école par le système Active Living by Design Community Action Model (vie active selon le modèle d'action de conception communautaire). Le système souligne cinq stratégies influençant l'activité physique : la préparation, la promotion, les programmes, les politiques et les projets physiques.

Relation of Modifiable Neighborhood Attributes to Walking

Rodriguez, DA
Aytur, SA
Forsyth, A
Oakes, JM
Clifton, KJ
2008
There is a paucity of research examining associations between walking and environmental attributes that are more modifiable in the short term, such as car parking availability, access to transit, neighborhood traffic, walkways and trails, and sidewalks. Adults were recruited between April 2004 and September 2006 in the Minneapolis-St Paul metropolitan area and in Montgomery County, Maryland using similar research designs in the two locations. Self-reported and objective environmental measures were calculated for participants' neighborhoods. Self-reported physical activity was collected...

The Role of Employment Subcenters in Residential Location Decisions

Cho, EJ
Rodriguez, DA
Song, Y
2008

In this paper we employ Mecklenburg County, North Carolina, a polycentric city with 10 employment subcenters, as a case study to explore the role of employment subcenters in determining residential location decisions. We estimate discrete choice models of residential location decisions: conditional logit models and heteroscedastic logit models with both the full choice set and sampled choices. We ënd that access to certain employment subcenters, measured in terms of generalized cost, is an important determinant of households’ residential location decisions. The proximity to speciëc...
