Available in PDF, EPUB and Kindle. Book excerpt: The "container revolution" of the last forty years has altered the manner in which transportation modes interact. Containerized freight continues to increase with ever larger ships, double stack train service, and trucking companies dedicated to intermodal container movements. The goal of "seamless" interaction between modes is based on a desire to reduce container dwell times at facilities and thus improve productivity and profitability. Consequently, the design of intermodal container terminals, the selection of appropriate lift equipment, and manpower allocation is of paramount importance to facility productivity. Tools for facility design undergo continual improvement. The current research is dedicated to developing a general simulation model of ship-to-rail intermodal container movements with the goal of providing analytical support to operations and facility design personnel

It is an essential reading for all stakeholders in the field of intermodal freight transportation, providing them with insight and tools to address the mounting academic and practical challenges in this segment of the transport and logistics market. Theo Notteboom, Journal of Transport Geography This book explores the great challenge of increasing the scope of intermodal freight transport. In view of the current dominant role of road transport and the increasing difficulties in coping with a growing number of vehicles in an efficient and sustainable way, intermodal freight transport could be considered a viable alternative. However, the book makes recognition of the fact that there is still a need to improve the performance of the intermodal transport system. The expert contributors provide an overview of the present role of intermodal freight transport, address opportunities to significantly improve current performance, and demonstrate design and modelling tools used to analyse and support this performance. Requirements for the implementation of intermodal innovations are also prescribed, and policies needed to improve competitiveness are outlined. Many factors contributing to the performance and competitiveness of intermodal freight transport are explored, from technological and organisational innovations through to institutional settings and policy frameworks. This comprehensive range of topics will attract a broad audience including academics, researchers, policymakers and practitioners involved in the design and development of freight transport systems. It will also strongly appeal to those with an interest in the future of freight transport.

Download or read book Integrated Intermodal Logistics Network Design written by Mohammad Ghane-Ezabadi and published by . This book was released on 2016 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermodal freight transportation uses at least two different transportation modes (e.g., truck, rail, ship, air) to move freight loads that are in the same transportation unit (e.g., a shipping container) from origin to destination without handling the goods themselves. The increasing shift to intermodal transportation and the growth of freight transportation demand have resulted in a higher demand for intermodal freight transportation that has been projected to grow even faster in the next few decades. Satisfying this emerging demand will require enhancing the capacity of current intermodal facilities or even the construction of new intermodal facilities. This research addresses the intermodal logistics network design problem which is one of the key strategic planning decisions related to intermodal transportation. To obtain the maximum performance of the intermodal logistics network, two relevant decisions corresponding to the route and mode selection for freight loads were integrated with the facility location problem within the integrated intermodal logistics network design (IILND) problem. To address the IILND problem, two mathematical formulations were developed. One considered making decisions about arcs of the network while the other considered making decisions about routes for origin-destination flows in the network. The arc-based formulation modeled the effect of consolidating freight loads at intermodal terminals on the transportation cost by a stepwise function that relates the per container transportation cost to the amount of flow between two nodes. A heuristic approach that combines a genetic algorithm and the shortest path algorithm was developed to efficiently obtain high quality solutions for the arc-based formulation. Unlike the arc-based formulation, the route-based formulation modeled the effect of consolidating different loads at intermodal terminals on the transportation cost and time using constant discount and delay factors, respectively. Moreover, a composite variable formulation was used for the route-based formulation to incorporate route feasibility constraints within the definition of the composites and avoid explicitly adding them to the model. These modifications reduced the number of variables and constraints significantly when compared to the arc-based formulation. Two solution approaches were developed to find optimal solutions for the route-based formulation, namely a decomposition-based search algorithm and an accelerated Bender’s decomposition method. Several sets of computational experiments were completed to evaluate the performance of the proposed mathematical formulations and solutions approaches. Finally, several general insights about the effects of design parameters on solution characteristics were obtained from the computational experiments and directions for future research were identified.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this dissertation is to develop models and solution approaches to identify the critical hierarchies of railroad and surface transportation network infrastructures, and to facilitate re-routing options that will be necessary for traffic management decision makings in the event of a disaster. We focus on building mathematical models for routing/re-routing of traffic considering the congestion effects which are obvious in the disrupted networks due to disaster. Based on these models, the critical hierarchies of infrastructures are determined. For railroad, we develop two different models: the first one considers 'unit' train re-routing and the other one considers Train Design approach. For intermodal system, the optimization model facilitates optimal re-routing of traffic using three surface transportation modes: highway, railway and waterway, considering the congestion characteristics of each mode. For the first model of railroad routing, the optimization model optimally routes unit trains based on a minimum cost network flow formulation with nonlinear objective function. The nonlinear objective function is approximated with a piece-wise linear function to make the model computationally tractable. The second model, known as Train Design optimization, is a highly combinatorial and complex optimization problem. The developed model's computational complexity suggests us to use heuristic solution procedures. We develop a special heuristic algorithm to route the traffic in the congested network. In this heuristic procedure, we divide the problem into two sub-problems (SPs): SP-1 is termed as Block-to-Train Assignment (BTA) problem, and SP-2 is termed as Train Routing (TR) problem. BTA problem provides a feasible solution that includes the minimum number of required trains with the pick-up and drop-off points of the blocks carried by these trains, and TR problem ensures the optimal routing of these trains. Similar to railroad, an optimization model is developed for optimal routing/re-routing of traffic using the intermodal network. It is a mixed integer programming (MIP) problem, which is not practical to solve for real-world problem instances within reasonable amount of time. Linear relaxation to this model provides a very good lower bound closer to optimal solution. Therefore, we implemented our case-study for a real-world intermodal transportation system of five U.S. states.

This book was released on 2020-06-03 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeder transit system (FTS) aims at arranging access to vehicles located at different depots at all demand points and transporting residents from these selected pick-up stops to transportation hubs (rail station and airport etc.). The FTS transit network, including a set of nodes (transportation hubs, bus stops, demand points, and depots) and links between them, is regarded as an effective tool to provide a better first/last mile service to and from the major fixed-route transit networks. The first/last mile access to major fixed-route transit networks and connectivity of residential areas is one of the main challenges faced by public transit. A well-designed FTS transit network shifted transport demand from individual car traffic to public transport and further enhanced urban sustainability. A feasible solution to the problem is the planning, design and implementation of efficient feeder transit services.

Book excerpt: An intermodal commuter network is an integration of passenger transportation systems, or modes, to a single comprehensive system that provides connections among the various modes, and improved travel choices to users. In the system examined in this dissertation, commuters access their final destination via auto, rail, and intermodal auto-to-rail modes. There are numerous highway paths by which a commuter can reach the final destination. Once on the highway, the commuter can switch to rail at stations along the rail route. The commuter may also choose to walk to the rail station closest to the trip's origin. The main focus of this dissertation is the development of models that can estimate traffic volumes and travel costs on intermodal networks. The particular approach used in the models is demand and supply equilibrium where transportation flows are impacted by the performance of the transportation facilities. Several optimization models are formulated based on sound mathematical and economic principles, and their equilibrium conditions are derived and stated clearly. A rigorous analysis of the mathematical properties of the models proves that these conditions are satisfied from the model solutions. The objective of these models is to alleviate some of the deficiencies encountered in the urban transportation planning process. A methodological framework is proposed which utilizes the models to analyze and evaluate operating and pricing policies in intermodal networks. The framework is designed to answer questions of interest to transportation planners, and to investigate the trade-offs between reduction in travel time and the increased cost of capacity improvements. To link theory and practice, the models are applied, within the proposed framework, to the analysis of a real-world intermodal commuter network. Policies aimed at improving the service quality of the intermodal network are evaluated based on their benefits compared to existing conditions. The models are also used to design an optimal rail transit service by computing rail fares and headways to meet future demands. The results of the analysis can be used by transportation planners, decision makers, transit operators, and transportation system managers to find effective ways to alleviate congestion on transportation systems. To this end, this dissertation points to areas of future research to further improve the proposed models.
