Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the development of geographical information systems (GIS) based tools for use in the trucking industry. The primary goals are to link the GIS with appropriate database information to support both operational and strategic decision making in both truckload (TL) and less-than-truckload (LTL) operations. The GIS-based tools support three primary deliverables. In the LTL industry, we have developed tools to support the determination of near-optimal locations for breakbulk terminals. In the TL industry, we have developed tools to aid in the development of regularly scheduled capacity in the form of driving "lanes" in an effort to regularize the driving job and to improve service in that industry. For both industries, we have made use of regression analysis to determine the level to which we can make use of demographic information to predict freight density. For all three deliverables, the GIS software system supports the key prerequisite of freight density analysis. Also, the GIS platform provides excellent graphics capabilities for visualizing the various analyses and solutions. The result is an integrated solution platform that enables the trucking industry to better utilize delivery capacity and to proactively seek solutions to problems of strategic importance

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to demonstrate usage of Geographical Information Systems (GIS) for analyzing intermodal freight networks. A complete GIS network, focused on the state of Texas, is developed and used to examine impacts of price, time, location, and policy on shipper routing. This process begins with an exploration of existing GIS applications, and state of the practice within the intermodal freight industry. This information provides a framework for building a technically feasible and relevant application. Data acquisition and processing techniques for both geographic and attribute data are considered. Relevant processes for creation of a GIS network and data conflation are identified and demonstrated. These techniques are used to create a network modeling the complex interactions and transfer rules amongst modes. Finally, several case studies are developed using the completed network to exhibit the power of GIS applied to intermodal freight. The report concludes with a summary, and observations to assist others attempting to build upon these results.

Available in PDF, EPUB and Kindle. Book excerpt: Federal planning legislation and regulations now mandate that state departments of transportation and metropolitan planning organizations consider the needs of freight when planning and programming transportation investments. While there are standard techniques used to forecast the movement of people, less attention has been paid to forecasting freight movements, and there are consequently fewer standardized techniques that state and local agencies can adapt to their local situation. This Toolkit is designed to provide transportation planners with the information they need to prepare forecasts of freight transportation by highlighting techniques successfully developed by state agencies across the country.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increase in truck traffic on highways has brought many problems and challenges to transportation planning and traffic operation, including traffic congestion, transportation system deficiency (insufficient truck parking, etc.), safety, infrastructure deterioration, environmental impacts (air quality and noise), economic development, and so forth. Along with the increase in truck traffic, the need for developing a statewide truck freight demand model has grown so that a state can estimate truck traffic at any point on its highways. The most significant hurdle to including freight transportation in the transportation modeling process is that most of the demand forecasting methodologies currently available were developed for passenger trips, not freight trips. This type of modeling methodology usually makes an assumption that freight trips follow the same behavioral mechanism as passenger trips. In order to overcome the weakness of using a typical four-step demand forecasting modeling process, the concept of commodity flow models (CFMs) can be used to develop a truck freight flow model. It is widely accepted that focusing on the freights enables CFMs to capture more accurately the fundamental economic mechanisms that drive freight movements. The type of commodity being carried is one of the most important characteristics of truck movements, and it is sometimes a challenge to obtain such information from the carriers. Thus, lately, the integration of the freight flow modeling and land use modeling has emerged as an alternate tool to estimate freight movements than the previously developed models. In this study, county-level multiple regression models relating land use to commodity flow were developed using a geographical information system and statistics. Then, a statistical/mathematical statewide commodity flow distribution model was developed by using a physical friction factor (physical distance), a statistical friction factor (Euclidean distance), and economic factors (differences of population and difference of employment among the counties). The commodity flow distributed among truck traffic analysis zones (TTAZs) by the statewide commodity flow distribution model were converted to truck trips and the resulting truck trips were assigned to Utah's truck routes using the all-or-nothing assignment procedure of TransCAD and a genetic algorithm. Truck freight data from the US Census Bureau's Commodity Flow Surveys, which have become available to the public for free via the Internet, enabled the development of a commodity flow based statewide truck freight demand model. It was found that the integration of the freight flow and land use data could be a practical method for modeling tuck traffic demand on state-wide truck routes although the current level of data availability on commodity flow and land use data still constrains the full capability of this type of modeling.

This book was released on 2006-03-30 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: One aspect of the new economy is a transition to a networked society, and the emergence of a highly interconnected, interdependent and complex system of networks to move people, goods and information. An example of this is the in creasing reliance of networked systems (e. g. , air transportation networks, electric power grid, maritime transport, etc. ) on telecommunications and information in frastructure. Many of the networks that evolved today have an added complexity in that they have both a spatial structure – i. e. , they are located in physical space but also an a spatial dimension brought on largely by their dependence on infor mation technology. They are also often just one component of a larger system of geographically integrated and overlapping networks operating at different spatial levels. An understanding of these complexities is imperative for the design of plans and policies that can be used to optimize the efficiency, performance and safety of transportation, telecommunications and other networked systems. In one sense, technological advances along with economic forces that encourage the clustering of activities in space to reduce transaction costs have led to more efficient network structures. At the same time the very properties that make these networks more ef ficient have also put them at a greater risk for becoming disconnected or signifi cantly disruptedwh en super connected nodes are removed either intentionally or through a targeted attack.
