Summary:
As congestion increases, transportation agencies are seeking regional travel time data to determine exactly when, how, and where congestion affects freight mobility. Concurrently, a number of regional intelligent transportation systems (ITS) are incorporating various technologies to improve transportation system efficiency. This research explored the ability of these ITS devices to be used as tools for developing useful historical, and perhaps real-time, traffic flow information.

Summary:
Loading ships as they are unloaded (double cycling) can improve the efficiency of a quay crane and container port. This paper describes the double-cycling problem, and presents solution algorithms and simple formulae to determine reductions in the number of operations and operating time using the technique. We focus on reducing the number of operations necessary to turn around a row of a ship. The problem is first formulated as a scheduling problem, which can be solved optimally.

Summary:
This paper documents the development of data collection methodologies that can be used to measure truck movements along specific roadway corridors in Washington State cost-effectively. The intent of this study was to design and test methodologies that could provide information to ascertain the performance of freight mobility roadway improvement projects. The benchmarks created would be used to report on speed and volume improvements that resulted from completed roadway projects.

Summary:
This report examines the relationship between Intelligent Transportation Systems (ITS) and safety from an urban perspective. Existing urban ITS systems are either system-level or site-level applications. System-level ITS, such as freeway management systems or traffic signal networks, address safety concerns only indirectly. These systems are designed to improve traffic flows and thus indirectly reduce collisions caused by congestion.

Summary:
Looking to go offshore, or improve your current offshore operations? A demand-driven supply chain strategy may be the answer. Here’s how to build one. “I’d like the filet mignon—please make that well done, but juicy!” As anyone who’s ever waited tables knows, sometimes the requests you get are just unrealistic.

Summary:
The Clean Trucks Program is a Clean Air Action Plan initiative currently being adopted by the Ports of Los Angeles and Long Beach. This paper examines the Clean Trucks Program’s current requirements and estimates the impact on terminal operations. Using terminal operations data supplied by three terminal operating companies, we conduct a simple queuing analysis and present a regression model that allows us to consider the potential impact of the policy changes.

Summary:
Variable service times at vehicle processing facilities (borders, weigh stations, landside marine port gates) cause transportation planning challenges for companies that regularly visit them. Companies must either build more time into their schedules than is necessary, and therefore underutilize their equipment, or risk missing delivery windows or exceeding hours of service regulations, actions that can result in fines, lost business opportunities, or other logistical costs.

Summary:
In this paper we present a profile of US/Canada border operations in the Western Cascadia Region, which lies between the Greater Vancouver and Puget Sound megacities. We show how this border is distinct from the more commonly discussed US/Canada border between New York, Michigan, and Ontario, in that commodities are typically less time sensitive, and a larger proportion of trips are made intra-regionally. Border procedures are described, as well as current programs for expedited crossings.

Summary:
The proposed research will address an emerging need by local, state and regional transportation planners and policymakers to better understand the transportation characteristics, functions and dynamics of ocean port-to-handling facility and handling facility-to-final market freight movements. The research will also address a gap in the academic literature for freight transportation models that capture underlying economic forces.

Summary:
This paper discusses the transport of containers between the Port of Prince Rupert and the hinterland. The result of several data collection and analysis efforts, we present a set of findings regarding the role Prince Rupert might play in North American transportation, and the particular strengths or weaknesses of this facility. In the short term, there will be no facilities for container rehandling in Prince Rupert.

Summary:
This report examines pedestrian and motorist behavior on arterials in Washington State and determines how, if at all, these behaviors change when various engineering treatments are applied. The treatments that were examined included crosswalk markings, raised medians, in-pavement flashers, signage, stop bars, overhead lighting, and sidewalks. The relationships between pedestrian travel and transit use, origin-destination patterns, traffic signals, and schools were also explored.

Summary:
Life Cycle Assessment (LCA) is a model-based approach to quantify where, and in what form, energy and materials are used in industrial production. The “life cycle” refers to the production of raw materials for fuels, infrastructure and energy conversion equipment, use, maintenance, after life options, and relevant health and social factors. This is sometimes referred to as a “cradle to grave” approach when assessing environmental impacts.
