In this paper we elaborate on the usage of multi-agent-based simulation (MABS) for quantitative impact assessment of transport policy and infrastructure measures. We provide a general discussion on how to use MABS for freight transport analysis, focusing on issues related to input data management, validation and verification, calibration, output data analysis, and generalization of results. The...

The transportation sector is a complex system. Collecting transportation activity and the associated emissions data is extremely expensive and time-consuming. Grey Relational Analysis provides a viable alternative to overcome data insufficiency and gives insights for decision makers into such a complex system. In this paper, we achieved three major goals: (i) we explored the inter-relationships...

Energy shortage and atmospheric pollution problems are getting more serious in China, and transportation is the main source of energy consumption, pollutants, and carbon emissions. This study combined the activity-based analysis method with emission models, and investigated the influence mechanism of people’s activity travel scheduling on transportation energy consumption and emissions on holid...

On behalf of the Natural Resources Defense Council (“NRDC”) and our 1.2 million members and activists, I appreciate the opportunity to comment on the CPUC’s Staff White Paper, Light-Duty Vehicle Electrification in California: Potential Barriers and Opportunities. 1 The document will serve as an important tool to stakeholders and policymakers working on reducing barriers to electrification in th...

Public policy and individual incentives determine the patterns of human mobility through transportation networks. In the event of a health emergency, the pursuit of maximum social or individual utility may lead to conflicting objectives in the routing strategies of network users. Individuals tend to avoid exposure so as to minimize the risk of contagion, whereas policymakers aim at coordinated ...

In many practical situations the coordination of transportation management and inventory management may lead to considerable cost reductions. Transportation management includes the application of different types of shipment consolidation policies. Shipment consolidation takes into account the logistics strategy of combining two or more shipment orders to optimize transportation. When the shipme...

Communicating public health issues related to rural and urban road transportation safety is a challenging task. The approach to this task was to utilize an action-design research methodology to design and evaluate several innovative GIS-mashups that visually communicate traffic fatality information from the national to the local level. These web-based mashups (www.saferoadmaps.org) integrate a ...

Given many public services previously delivered by federal and state entities continue to devolve to more local levels of service delivery and programmatic control, interorganizational coordination serves as an approach for the public sector to ensure that services are efficiently delivered in a nonduplicative manner. This article explores the issue of coordination by examining three different ...

Amid growing concerns about the impact of rising obesity and physical inactivity levels, climate change, population growth, increasing traffic congestion and declining oil supplies, multiple sectors are now promoting active transportation as an alternative to driving. This paper considers the health benefits and co-benefits of investing in active transportation, enabling comparison of policy op...

CONTEXT Complete Streets policies guide planning in communities by making the transportation system accommodating to all users including vehicle drivers, pedestrians, and bicyclists, as well as those using public transportation. While the number of Complete Streets policies has increased over the past decade, no research has explored the factors attributing to the widespread diffusion of these ...
