Since completing a " Trend-Delphi " based regional forecast and transportation plan in 1996, Metro has developed an integrated transportation and land use model (Metroscope). We are presently using the model to explore several regional growth management options as well as produce a new regional forecast and transportation plan. Comparing our Metroscope results to our previous forecast reveals t...

This paper investigates the impacts inventory shortage policies have on transportation costs in base-stock distribution systems under uncertain demand. The model proposed demonstrates how backlogging arrangements can serve to decrease the variability of transportation capacity requirements, and hence the magnitude of transportation costs, when compared with policies that expedite demand shortag...

INTRODUCTION This study assessed correlates of self-reported local health department (LHD) participation in community policy/advocacy activities that support physical activity. METHODS In 2014, cross-sectional data from the nationally representative 2013 National Profile of Local Health Departments study administered by the National Association of County and City Health Officials were analyze...

Energy issues in transportation systems have garnered increasing attention in recent years in both the public and private sectors. This study proposes a systematic methodology for policy-makers to improve energy consumption efficiency in multimodal intercity transportation systems considering suppliers’ operational constraints and travelers’ mobility requirements. A bi-level optimization model ...

While scholars have found several benefits to citizens, government, and society resulting from participatory policy processes, other research suggests that citizens are apathetic and uninterested in participating in policy-making. Also, in some cases, knowing that similar others participated in making a decision can decrease support for the result. The current research attempts to determine whe...

Policy planners often lack guidance in their approach to meet sustainability goals in transportation. Considering the multiplicity of actors involved and challenges to be met, as well as the intertwined impacts of transportation, a more widespread use of causal chain analysis seems relevant to improve the decision-making process. This paper illustrates the usefulness of the causal chain approac...

This paper discusses the evaluation of synergies that derive from the implementation of policy packages designed to promote the use of public transportation and limit traffic congestion in urban areas. In this study, we propose the application of a land-use and transportation integrated (LUTI) model to study the outcomes from the implementation of two policy packages. We apply the long-term str...

PURPOSE To examine the role of land use and transportation plans as policy instruments for promoting active community environments. DESIGN Cross-sectional analysis using multilevel models to examine whether active community environment scores were associated with leisure and transportation-related physical activity (PA) and whether associations varied by household income. SETTING 67 North C...

  The main purpose of this study is to estimate the maritime transportation elasticities of the environmental pollution and economic growth in Iran within the short-run and long-run to find out the relationships among maritime transportation, environmental pollution and economic growth. The lagged endogenous model (a dynamic log-linear model that we used) is estimated using two distinctive ...
