Modelling The Transport Sector In India : A Study On Intermodal Substitution Passenger Transport

Vasudevan, S 05 1900 (has links)
Transportation infrastructure has long been recognized as the sine qua non of rapid economic development. As a predominantly agrarian economy with a vast and growing population spread over an extensive mass of land, India presents a veritable case of this truism, sadly by the lack of it. Notwithstanding the vagaries of development in other sectors, the transport sector in India, ironically, has received scant attention over five decades of the planning era, which has lent itself to lop-sided development in favour of the railways. Though deregulation and attendant economic reforms have augmented transport services by air and road in the last decade, the inadequacy of transport infrastructure and the acute paucity of resources to fulfil the provision of the same have been the bane of problems confronting the government. Privatization as a solution to circumvent resource constraints has raised new issues of social and environmental equity, which transcends the immediate concerns of infrastructure development. As is evident, though the solutions to the problems of the transport sector are multifarious, they emphasize the imperative need for rational and integrated transport planning and policy. A cursory look at the problems plaguing this sector also reveals that the issues and concerns cannot be dealt with in its entirety. Against this background, we confine ourselves to the study of the passenger transport sector and attempt to address an interesting and increasingly apparent phenomenon of travel behaviour, namely intermodal choice and modal substitution. The genesis of this study was an earlier work done by a research team at the Centre for Mathematical Modelling and Computer Simulation (C-MMACS), NAL, where in, a general methodology to describe the growth of the transport sector in India was developed in terms of appropriate mathematical models. Significantly most of the variables describing demand, supply and performance were found to trend exponentially. However, the models failed to reflect the trends in intermodal substitution and its significance in evaluating future transport demand. For example, the development or availability of alternative means like rail or personalized vehicles may influence the demand for bus transport. Similarly demand for air transport may be a function of comparative advantages presented by alternatives like upper class rail travel. This phenomenon is observed to be pronounced on short-haul routes characterizing inter-city travel, where such modes are extremely competitive. We consider a regional network of high-density routes in southern India, as a representation of several such transport networks across the country, to study this phenomenon and its implications for future policy. The primary objective of this study is to develop and evaluate a set of econometric models that would adequately measure the extent of intermodal substitution in passenger transport on short-haul routes (inter-city travel) and, critically evaluate the factors that affect travel choice in a multimodal environment. Toward this, the study is divided into three parts. Part one focuses on understanding broad trends in air, rail and road travel, for the routes in consideration. Suitable regressions are estimated to measure the effect of critical transport variables on route-wise travel demand. The coefficients are estimated separately for two categories of travel - First Class and Second Class. Part two of the study is based on data collected from individual travel surveys on the route network. A simplified questionnaire was used for this purpose. We use the traditional logit framework to estimate choice probabilities based on user perceptions about factors affecting their choices. As in the previous case, we estimate the logits for both classes of travel, viz. First Class and Second Class, under the equal substitutability assumption. We also estimate the logits for the general case for the sake of comparison, though not practicable. Part three involves a case-study of an alternative high-speed rail link for one of the routes in the network having the highest traffic density, to illustrate its effect on travel choice in a multimodal transport network. We also demonstrate the feasibility of the project using a benefit-cost approach. From the results, it is observed that substitution is predominantly from air to rail for "first-class" travel, and from rail to road for "second-class" travel. Besides, it is also observed that travel choice is largely influenced by non-price (fare) considerations. The value of travel time is estimated for both categories of travel, using the trade-off method and is found to be significantly different. All regressions show a high and the coefficients are significant at the 5% level. The logit analysis validates the earlier conclusion that non-price (fare) factors influence the demand for different modes. It is found that users attach considerable importance to comfort and convenience, including time of travel, while making travel choices. It is also observed that the logits vary significantly when factors are grouped, and further, between categories of travel In the case of the high-speed link, we estimate that there will be a significant shift in travel demand from air to rail and also from road to rail, given substantial travel time savings. The estimates of passenger revenue and decongestion benefits also provide a strong rationale for the implementation of the project. Sources of data include published and unpublished records of Indian Airlines, Indian Railways and State Road Transport Undertakings (SRTUs) on air, rail and road travel respectively. Data on population and other macroeconomic variables were obtained from census records and similar statistical publications. An important feature of this study is its attempt to bridge the macro and micro policy environments. It is one of the first attempts to study the dynamics of travel demand and choice behaviour in a multimodal regional transport network in India. Unlike previous studies, it transcends the realm of urban transport economics and extends its scope to the study of regional transport characteristics, where inter-city passenger travel has undergone significant changes both in environment and behaviour in the last decade. The entire study has been conceptualized in a system dynamics framework to describe its relevance to overall transport planning. It is believed that such an exercise would be a precursor for the development of a full-fledged macroeconomic model of the transport sector in India.

The relevant market : From an air passenger perspective

Sioulas, Andreas January 2010 (has links)
<p>This thesis intends to analyze and clarify the relevant market within air passenger transport. Further the thesis intends to investigate if there is any difference in air passenger transport in accordance to more general business. The definition of the relevant market is an essential step in order to establish a breach under European competition law. The relevant market includes the relevant product market and the relevant geographic market. The fundamental issue in the relevant product market is whether products are considered to be substitutable and can constitute the same market. The Commission has set a notice which includes methods and criterias and serves as guidelines to courts and companies to define the relevant market. The notice is however not binding for courts. The CJ have developed implementation of the criterias which it tends to refer to even if it is a different branch, however a case-by-case based definition is needed. The definition of the relevant market is based on three main criterias: demand substitutability, supply substitutability and potential competition. Even though the supply substitutability seems not be implemented in a further extension in more general branches, it seems to be of greater importance when defining the relevant market within air passenger transport. The air passenger transport has also established a test called base of origin and base of destination which includes an analysis of price, travel frequencies, comfort of the journey, transfer time to terminals and differences in the qualities and quantities in airports.  However according to air passenger transport, travel sequences seems to be the criteria that courts focus most on.</p>

In Whose Interest? A Critical Approach to Southeast Asia’s Urban Transport Dynamics

townsend@alcor.concordia.ca, Craig Townsend January 2003 (has links)
During recent decades, urban transport systems in Southeast Asia’s industrialising high growth economies were transformed. The ownership and use of privatelyowned cars and motorcycles grew in all cities, simultaneous to the introduction of new forms of public transportation including rail rapid transit in the larger metropolises. While these cities all experienced dynamic change, the relative rate and direction of the changes to urban transport systems varied greatly as did levels of success. Singapore emerged as a highly efficient transit metropolis whilst Bangkok and other cities gained notoriety as some of the world’s great traffic disasters. Why these differences emerged, particularly given a regional and global context of increasing interaction and exchange of ideas and of capital flows, presents a compelling question largely unanswered by previous research. A review of the general state of knowledge about urban transport worldwide reveals fundamental disagreements over basic questions such as the social value of motorisation, the relative merits of specific modes and technologies, and prescriptions for change. However, there is a general consensus that interest groups or rent-seekers influence urban transport, which can not be understand in solely technical or value-free terms. A literature review focused on Southeast Asian cities finds that in contrast to theoretical perspectives on cities of the industrialised world, there is less acknowledgement of interests and values and more emphasis on instrumental knowledge which can be used to address immediate problems such as rapid growth in motorisation, traffic congestion, and pollution. Questions such as who wins and who loses from changes to urban transport systems are not systematically examined in the existing literature on Southeast Asian cities. In order to address this gap, a case study analysis of three key cities, Bangkok, Kuala Lumpur, and Singapore is undertaken. This analysis utilises policy and planning documents, monographs and academic works, newspapers and archival materials, discussions with key informants, and participant observation, to reveal the significant actors and processes which shape urban transport. The study finds that the presence or absence of actors and complexions of interests in the development of urban land, urban transport equipment, infrastructure construction and operation, and local environmental improvements are linked to specific urban transport outcomes. The findings provide a basis for future research, particularly in cities of the developing world characterised by economic growth, rapid motorisation of urban transport systems, and substantial inequalities of wealth and power.

In this scenario, measure and control the logistic costs represent a source for competitive advantage and cost reductions. The company studied in this work is part of the passenger transport sector and, although it is subsidized, it still requires operational and financial improvements to ensure its operational sustainability. To this end, it was decided to measure the costs based on the logistics perspective. In this way, a literature review was performed to identify the main factors that imply in logistic costs. The methods RKW and ABC were used to compute these costs, generating data coherent to the main objective, and tailoring its steps according to the company characteristics. Finally, it was verified that the logistic costs in the studied company represents 36,5% of total costs. Although the literature points out that logistic costs usually represent 10% of total costs, the obtained value is compatible, once the company is a service provider, and large portion of (labor) costs are related to the implementation of logistic activities. Conceptually, the methods applied were compatible with the primary objective of the study, allowing the identification and measurement of the logistic costs. The achievement of this objective simplify the activity of cost control, allowing better targeting the actions to reduce them. / A logística tem assumido uma posição de destaque no mercado. Essa importância está intimamente ligada à complexidade das operações frente aos requisitos de mercado. Diante deste cenário, mensurar e acompanhar os custos de natureza logística tem se mostrado fonte de vantagem competitiva e de redução de custos. A empresa estudada neste trabalho está inserida no setor de transporte de passageiros e embora seja subsidiada vem apresentando necessidades de melhorias operacionais e financeiras, no intuito de garantir a sustentabilidade das operações. Por este motivo definiu-se como objetivo mensurar os custos sob a perspectiva dos custos logísticos, no intuito de identificá-los. Para tanto, efetuou-se uma pesquisa bibliográfica para rastrear os fatores geradores dos custos logísticos. Para o cálculo deste tipo de custo, utilizou-se a união de dois métodos de custeio, RKW e ABC, para promover a obtenção de dados coerente ao objetivo principal, adequando as etapas de sua implementação às características da empresa. Ao final, verificou-se que o custo logístico da companhia representou 36,5% dos custos totais. Embora a literatura indique que os custos logísticos normalmente representem 10% dos custos totais, o valor se mostrou compatível uma vez que a CBTU/JP é uma prestadora de serviço e a grande parcela de custos da empresa (custos de mão de obra) estão relacionados à execução das atividades logísticas. Em termos conceituais verificou-se compatibilidade dos métodos utilizados com o objetivo principal do trabalho, de mensurar os custos logísticos permitindo sua identificação. O atendimento deste objetivo facilita a atividade de controle dos custos e permite um melhor direcionamento das ações para sua redução.

Přířazovací problém a jeho praktická aplikace v oblasti přepravy osob / Assignment problem and its particular application in passenger transport

Asterová, Jana January 2017 (has links)
This thesis is focused on the topic of assignment problems. The theoretical part presents a summary of the most important previously published findings on linear and quadratic assignment problem. The basic formulations of both problems are introduced, as well as the outline of some methods developed for their solution. Finally both problems are illustrated by practical applications that have appeared in the literature. The practical part gives insight into the issue of assignment of transport orders to drivers in a company and proposes a suitable model that speeds up the process of distributing the orders. The transfers conducted by the company start at the airport and terminate in a hotel in the city centre of Prague or vice versa. When proposing order schedules for the drivers, it is necessary to take into account not only the time of the transfers, but additionally the capacity and the category of the vehicle.

Understanding the Impacts of Weather and Climate Change on Travel Behaviour

Chengxi, Liu January 2016 (has links)
Human behaviour produces massive greenhouse gas emissions, which trigger climate change and more unpredictable weather conditions. The fluctuation of daily weather corresponds to variations of everyday travel behaviour. This influence, although is less noticeable, can have a strong impact on the transport system. Specifically, the climate in Sweden is becoming warmer in the recent 10 years. However, it is largely unknown to what extent the change of travel behaviour would respond to the changing weather. Understanding these issues would help analysts and policy makers incorporate local weather and climate within our policy design and infrastructure management. The thesis contains eight papers exploring the weather and climate impacts on individual travel behaviour, each addressing a subset of this topic. Paper I explores the weather impact on individual’s mode choice decisions. In paper II and III, individual’s daily activity time, number of trips/trip chains, travel time and mode shares are jointly modelled. The results highlight the importance of modelling activity-travel variables for different trip purposes respectively. Paper IV develops a namely nested multivariate Tobit model to model activity time allocation trade-offs. In paper V, the roles of weather on trip chaining complexity is explored. A thermal index is introduced to better approximate the effects of the thermal environment. In paper VI, the role of subjective weather perception is investigated. Results confirm that individuals with different socio-demographics would have different subjective weather perception even given similar weather conditions. Paper VII derives the marginal effects of weather variables on transport CO2 emissions. The findings show more CO2 emissions due to the warmer climate in the future. Paper VIII summaries the existing findings in relations between weather variability and travel behaviour, and critically assesses the methodological issues in previous studies. / <p>QC 20160516</p> / Understanding the complexity of changes of travelers’ activity-travel choices and related transport CO2 emissions due to the variation of weather and climate in Sweden (Centre för Transport Studie, projekt kod: 446) / Understanding the impacts of weather and climate change on travel behavior (Centre för Transport Studie, projekt kod: 291)
