This book was released on 2017 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword: "NCFRP Research Report 37 provides policy makers with improved establishment-level models that estimate the freight trip generation (FTG), the number of vehicle trips produced and attracted at a given establishment; the freight production (FP), the amount of cargo produced by the establishment; and the service trip attraction (STA), the number of vehicle trips that arrive at the establishment to perform a service activity. These models, estimated with the best data available, provide tools to assess the various facets of the overall freight and service activity (FSA) that takes place in urban and metropolitan areas. The models will allow transportation practicitioners to conduct sound curb-management, proerply size loading and unloading areas, support traffic impact analyses, and improve transportation planning and management efforts."--Page v.

Download or read book Moving Forward written by Matías Herrera Dappe and published by World Bank Publications. This book was released on 2019-10-30 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: The erosion of its competitiveness is raising concerns about the sustainability of Bangladesh's growth model based on exports of ready-made garments. To safeguard its comparative advantage in ready-made garments and diversify its exports basket, Bangladesh needs to increase its competitiveness. Improving logistics performance is an important lever with which to do so. Moving Forward: Connectivity and Logistics to Sustain Bangladesh's Success presents a comprehensive assessment of logistics performance and its main determinants. It analyzes freight demand at a spatially disaggregated level, quantifies logistics costs, including the costs of externalities, looks at the factors that determine the stock and quality of infrastructure, and examines the incentives to provide logistics services of a certain type and quality and to charge the observed prices. It also quantifies the potential impacts of removing transport and logistics inefficiencies on Bangladesh's exports and economic geography using a spatial general equilibrium model. Bangladesh's congested, unreliable, and unsophisticated logistics system imposes high costs on the economy. Making it efficient requires a holistic system-wide approach that is based on a comprehensive strategy; improves the quality, capacity, and management of infrastructure; improves the quality and integration of logistics services; and achieves seamless regional connectivity. Moving Forward will be of interest to policy makers, private sector practitioners, and academics with an interest in the performance of Bangladesh's transport and logistics sectors.
Download or read book Estimating Freight Origin Destination Matrices Using Combined Commodity Flow Survey and Roadside Survey Data written by and published by . This book was released on 2009 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paucity of available data was limiting studies of freight flow in Thailand. To overcome this problem, commodity flow survey (CFS) and comprehensive freight transportation by truck using roadside survey (RS) were launched to collect comprehensive freight flow data throughout the kingdom of Thailand. Since these two surveys were pioneering and due to budgetary limitations, the resulting data are still incomplete and must be adjusted. The need to produce a freight origin destination matrix using available data from CFS and RS led to the objectives of this research. This research has two main objectives. The first is to develop a methodology for combining CFS and RS. The second is to develop a method for filling gaps in the origin destination matrix based on the Adaptive Neuro Fuzzy Inference System (ANFIS) approach. The methodology to combine these two data sources was developed which uses the strengths of each method, the CFS distribution pattern and the RS marginal total. The first method is Trip Length Distribution Adjusting (TLDA), which uses adjustments to CFS trip length distribution to meet RS marginal total. The second method is Gravity Model Approach (GMA), which uses CFS friction functions to adjust RS data matrix. The method was calibrated using two difference sources of roadside survey. The results indicated that the adjusted volumes of the two data sources agreed despite being collected at different times and by different authors, and that the differences between the total adjusted volumes were quite small. It can therefore be concluded that the developed method can be used to adjust the data. For the second component, a model using BOX-COX transformation and Adaptive Neuro Fuzzy Inference system (ANFIS) was developed and verified against a convention gravity model. Two types of model, using convention gravity variables and using socio-economic variables, were developed. The results showed that the ANFIS model outperformed both the conventional gravity model and the BOX-COX model. These results proved the performance of the adaptive neuro fuzzy inference system for modeling complex system and its ability to model freight trip distribution.

Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on establishing a systematic non-survey-based method for developing an origin-destination (OD) matrix of freight flows based on secondary data sources. The estimated freight flows and concurrent passenger volumes are loaded onto the regional highway network in the greater Los Angeles area of Southern California. Economic analyses, modeling, and GIS technologies are integrated into building a GIS-based OD matrix for freight flow. In order to load the freight flows onto the regional highway network, a three-step feedback transportation model is developed. It includes trip generation, trip distribution, and traffic assignment. A doubly-constrained gravity model is used to co-distribute and calibrate personal trips and freight trips in the trip distribution step. A version of User-Optimal-Strict On Network Assignment (UO-S-NA) is used to assign all of the vehicle trips to the regional highway network.
Download or read book Using Commodity Flow Data for Predicting Truck Freight Flow in State Truck Routes written by Goangsung Jin and published by . 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 2012-11-02 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2007 Commodity Flow Survey (CFS) is undertaken through a partnership between the U.S. Census Bureau, U.S. Department of Commerce and the Research and Innovative Technology Administration (RITA), Bureau of Transportation Statistics (BTS), U.S. Department of Transportation. This survey produces data on the movement of goods in the United States. It provides information on commodities shipped, their value, weight, and mode of transportation, as well as the origin and destination of shipments of commodities from manufacturing, mining, wholesale, and select retail and services establishments. The CFS data are used by policy makers and transportation planners in various federal, state, and local agencies for assessing the demand for transportation facilities and services, energy use, and safety risk and environmental concerns. Additionally, business owners, private researchers, and analysts use the CFS data for analyzing trends in the movement of goods, mapping spatial patterns of commodity and vehicle flows, forecasting demands for the movement of goods, and determining needs for associated infrastructure and equipment. The CFS was conducted previously in 2002, 1997, and 1993.The economic census is the major source of facts about the structure and functioning of the nation's economy. It provides essential information for government, business, industry, and the general public. Title 13 of the U.S. Code (Sections 131, 191, and 224) directs the U.S. Census Bureau to take the economic census every 5 years, ending in "2" and "7." The economic census furnishes an important part of the framework for such composite measures as the gross domestic product estimates, input/output measures, production and price indexes, and other statistical series that measure short-term changes in economic conditions. Specific uses of economic census data include the following: Policymaking agencies of the federal government use the data to monitor economic activity and assess the effectiveness of policies; State and local governments use the data to assess business activities and tax bases within their jurisdictions and to develop programs to attract business; Trade associations study trends in their own and competing industries, which allows them to keep their members informed of market changes; Individual businesses use the data to locate potential markets and to analyze their own production and sales performance relative to industry or area averages. The economic census is conducted on an establishment basis. A company operating at more than one location is required to file a separate report for each store, factory, ship, or other location. Each establishment is assigned a separate industry classification based on its primary activity and not that of its parent company.

Book excerpt: This research effort develops a national freight mode choice model employing data from the 2012 Commodity Flow Survey (CFS). While several research efforts have developed mode choice model with multiple modes in the passenger travel context, the literature is sparse in the freight context. The primary reasons being unavailability and/or the high cost associated with the acquisition of mode choice and level of service (LOS) measures--such as travel time and travel cost. The first contribution of the research effort is to develop travel time and cost measures for various modes reported in the CFS. The study considers five modes: hire truck, private truck, air, parcel service and other modes (rail, ship, pipeline, and other miscellaneous single and multiple modes). The LOS estimation is undertaken for a sample of CFS 2012 data that is partitioned into estimation sample and holdout sample. Subsequently, a mixed multinomial logit model is developed using the estimation sample. The exogenous variables considered in the model include LOS measures, freight characteristics, and transportation network and Origin-Destination variables. The model also accounts for unobserved factors that influence the mode choice process. The estimated mode choice model is validated using the holdout sample. Finally, a policy sensitivity analysis is conducted to illustrate the applicability of the proposed model.

Download or read book Research Needs for Developing a Commodity driven Freight Modeling Approach written by Kathryn L. Peacock and published by . This book was released on 2003 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that better freight forecasting models and data are needed, but the literature does not clearly indicate which components of the modeling methodology are most in need of improvement, which is a critical need in an era of limited research budgets. This effort sought to identify those components using a logistics-driven approach as a starting point. The research began by examining other states' responses to freight planning legislation. A survey was sent to 47 states to determine the types of freight planning and freight modeling that occur and to understand the current data available and data needs. Research was conducted to gather information on how the supply chain functions and how logistics decisions regarding supply chain management are made. Sample supply chains were created for a variety of commodities, and mode choice was related to the behavioral aspects of the supply chain's logistics system. Once the mode was determined, the route assignment could be determined based on the accessible freight infrastructure. It was found that not all elements of the freight modeling methodology are equally weak: indeed, trip attraction components for the production of raw materials and the dissemination of these materials from the manufacturing plant, whether to the consumer (in a traditional push system) or to a just-in-time distribution center (in the newer pull system) are adequately developed in practice. However, it is critical that future research address the following needs, listed in order of descending priority: (1) the mode choice component for delineating travel by air, truck, rail, water, or a combination thereof; (2) trip attraction equations for intermodal facilities that are used when manufacturing plants outsource key components rather than creating all components in-house, and (3) trip attraction equations for representing the flow of goods from distribution centers to the consumer.
