This book deals with alignment optimization models for planning rail transit. After a general introduction to the basics of alignment optimization theory, it presents different alignment optimization methods to deal with different situations. It shows how to set up a 3D GIS scene for alignment interaction design, including location calculation of an alignment, alignment expression in a 3D scene, and the spacial relations between geographic objects, horizontal alignment, and vertical alignment. Further, it presents methods for solving more complex alignment optimization models, and shows for each different rail transit situation, how to calculate investment, energy consumption, and environmental influence. All in all, this book offers an interesting and timely reading to both researchers and professionals in the field of optimization theory, transportation planning, and GIS.

This monograph provides a comprehensive overview of methods for searching, evaluating, and optimizing highway location and alignments using genetic algorithms (GAs), a powerful Artificial Intelligence (AI) technique. It presents a two-level programming structure to deal with the effects of varying highway location on traffic level changes in surrounding road networks within the highway location search and alignment optimization process. In addition, the proposed method evaluates environmental impacts as well as all relevant highway costs associated with its construction, operation, and maintenance. The monograph first covers various search methods, relevant cost functions, constraints, computational efficiency, and solution quality issues arising from optimizing the highway alignment optimization (HAO) problem. It then focuses on applications of a special-purpose GA in the HAO problem where numerous highway alignments are generated and evaluated, and finally the best ones are selected based on costs, traffic impacts, safety, energy, and environmental considerations. A review of other promising optimization methods for the HAO problem is also provided in this monograph.

The increase in commuting populations and transit ridership in urban areas has given rise to the need for building new transit lines or extending existing ones. The objective of this dissertation research is to perform a microscopic analysis and develop models and algorithms for a rail transit alignment using Geographical Information System (GIS) and Genetic Algorithm (GA) in a given study corridor. Previous research suggests that several analytical methods have been developed to design various components of a transit system, such as optimization of station spacings, route spacing, and route length for rail transit alignments. While all this research has contributed substantially towards the development of a transit system, the applicability of these theoretical models remains limited for real-world problems. The present research aims to perform a microscopic analysis in a given study corridor to obtain the locations and sequence of stations considering many-to-one travel pattern, variable demand for transit, identification of feasible locations for stations and optimization of various objective functions for station locations for an optimal rail transit alignment through GIS-GA integration. An optimization algorithm is developed for optimizing station locations for three types of rail transit systems, namely (1) an on-the-ground rail transit system; (2) an underground cut and cover rail transit system, and (3) an underground deep tunnel rail transit system. The algorithm is developed in two stages. In the first stage, the search space is defined by identifying the potential station locations using a GIS and in the second stage a GA is applied to perform the optimal search. The optimization model for station location is developed using several objective functions of demand and cost as both influence the optimal rail transit alignment. The first objective is to minimize the total system cost per person, which is a function of user cost, operator cost, location cost and variable demand. A bilevel optimization model is introduced for the station location optimization problem. In this model a number of clusters of riders are determined from local population data at the lower level in order to estimate demand and optimize the objective functions at the upper level. The second objective is to maximize the ridership or the service coverage. The user cost per person is minimized separately as the third objective because the user cost is one of the most important decision-making factors for using the transit system. A decision can be made based on the preferred parameters by a transit-planner based on the results obtained using different objective functions. A variable demand case is considered in the research which replicates a realistic scenario that can be expected while planning a rail transit line Optimal solutions are obtained by running an iterative process of re-estimating the variable transit demand by varying the locations and sequence of stations, which results in change in travel time and potential transit demand. Once the optimal station locations are obtained, the stations are interconnected using a suitable rail line alignment. This is done by connecting each pair of stations using a GIS and GA based algorithm (customized Highway Alignment Optimization model). The proposed model is applied on an artificially generated study area of size 20 miles x 20 miles around Washington DC in USA. The efficiency of the proposed algorithm is verified on small scale examples first. Then the model is applied on radial corridors of 12 miles x 3 miles and a diagonal corridor of area 22 mile x 3 mile within the study area to obtain optimal rail transit alignments. The results show that a new rail line alignment can be established in a comprehensive, consecutive and automated process using the proposed model. Better results are obtained for radial corridors than for the diagonal corridor as many-to-one travel pattern is considered for the study. The iterative approach in the algorithm increases computational complexities but produces near optimal solution for a rail transit alignment. The results give a planner an initial idea about which objective functions to use for a specific type of study corridor under consideration. -- Abstract.

This book offers new insights into the wider socioeconomic impacts of high-speed rail (HSR). Over the past few decades, significant investments have been made in these systems around the world. The use of public funds for the construction of high-speed rail offers a range of benefits, such as time savings, increased comfort, and reduced traffic congestion, as well as broader economic benefits, including the advancement of less developed regions. These proceedings feature papers presented at the 2nd International Workshop on the Socioeconomic Impacts of High-Speed Rail. The focus is on HSR’s impacts on equity and integration, the land use system, productivity, the environment, the tourism industry, and cooperation and integration with other modes of transport. The book provides an overview of the current state of practice from both theoretical and empirical perspectives. Consequently, it will be of interest to scholars of transportation economics and related fields, as well as transportation industry professionals.
