Urban transportation externalities are a key development challenge. Based on the existing literature, the authors illustrate the magnitudes of various external costs, review response policies, and measure and discuss their selection, particularly focusing on the context of developing countries. They find that regulatory policy instruments aimed at reducing local air pollution have been introduc...

We optimize ordering and inbound shipment decisions for a manufacturer that sources multiple items from a single supplier. The objective is to satisfy the requirements in the production plan with minimum transportation and inventory holding costs over a multi-period planning horizon. Transportation costs are charged to the manufacturer on a per truck shipment basis. We investigate the option of...

Research experiments and product deployments of QoLT technologies for independent transportation have unique and profound ethics and policy concerns. Experimenters who run field studies can easily recount anecdotes involving real (e.g., crashes) and hypothetical (e.g., participant questions) scenarios where personal privacy concerns and legal requirements come into tension. Product deployment b...

This paper presents an analysis of the perceptions held by for-hire and private trucking company logistics and operations managers about the impacts of congestion on their operations and the feasibility and effectiveness of actual and potential congestion mitigation policies. Responses to an extensive survey of nearly 1200 California-based or large national carriers are examined using con®rmato...

Since the last two decades, container transportation system has been faced under increasing development. This fact shows the importance of container transportation system as a key role of container terminals to link between sea and land. Therefore, there is a continuous need for the optimal use of equipment and facilities in the ports. Regarding the complex structure of container ports, this pa...

In this project, we describe a real-time transportation route selection policy with traffic considerations. It is a dynamic policy that has a global perspective of the real-time traffic status. The A* search algorithm[4] is used to find the optimal route and the traffic status is the heuristic during the search. We created a map to simulate a real-word transportation network and a traffic file ...

We present the Transportation And Production Agent-based Simulator (TAPAS), which is an agent-based model for simulation of transport chains that can be used, e.g., for analysis of transport-related policy and infrastructure measures. TAPAS is more powerful than traditional approaches to freight transport analysis, as it explicitly models production and customer demand, and it captures the inte...
