Designing of Zone Tariff in Integrated Transport Systems

When designing a tariff system, there are several possibilities how to design the tariff. One of them is dividing the region into the zones. These zones are usually created by stops in one or more municipalities and the price of travelling between arrival and destination stops is determined by the number of travelled tariff zones by the passenger. There are various approaches how to design prices in such a system. In this article we introduce a mathematical model of the tariff zones design based on counting zones and introducing two approaches for designing prices within this system. We will focus on solving this problem using a universal optimisation tool Xpress, on data set of the selected region. We will compare both approaches in terms of solution quality and computational time.

Mode Shift Behavior Impacts from the Introduction of Metro Service: Case Study of Xi’an, China

Xi’an, as a typical inland city in China with a worse integrated transport system, has promoted the use of metro service to ease serious traffic congestion. This paper uses a logistic regression model to examine mode shifts behavior for auto, taxi, bus, electric bicycle, and bicycle users after the implementation of metro service based on stated preference data. The results indicate that auto travelers located in suburban regions are more willing to shift to metro for work trips. Female taxi and auto users are more likely to use metro than males. Longer trips for taxi and electric bicycle travelers prefer to choose the newly introduced metro. Additionally, a preference survey on newly opened metro concluded that metro passengers that shift from auto mode may decrease 8 to 19% because of incomplete transfer facilities. Finally, it was found that the impacts on easing traffic congestion by a single metro corridor are not significant, and some parallel policies need to be adopted. Furthermore, these findings are more useful for developing cities lacking modal joint and integration.

Study on Low-Carbon Development Status Quo and Countermeasures of Transportation in Shandong Province

The rapid development of the transportation industry in Shandong Province provides a fundamental guarantee for the economic and social development, but also brings a lot of energy consumption and pollutant emissions, directly affecting the construction of ecological Shandong. By investigating low-carbon development of the transportation industry in Shandong Province, this article analyzes the status of low-carbon development and identifies the problems: transportation structure is irrational; low-carbon development lacks corporate body; regulation of transportation energy saving needs to be strengthened. Put forward countermeasures for low-carbon development of the transportation in Shandong Province: speed up the construction of the integrated transport system; optimize transport organization; improve regulation of transportation energy; give full play to the leading role of science and technology to a low-carbon economy; strengthen low-carbon economic subject consciousness of transportation enterprises; develop public low carbon transport consciousness.

Multi-Agent Competition Simulation of Integrated Transportation System

Transportation networks have been developed during the recent decades with the rapid growth of economy. At the same time, the conflicts between different transportation modes were getting more and more intense. To describe the competition relationship in integrated transportation system, a multi-agent competition model was presented. It is important to provide decision support for regulators to lead more reasonable distribution of resources for planning and operating the integrated transportation network. Thus, a simulation program was developed to implement the proposed model and provide computer-aid decision support. Finally, several experiments were conducted to illustrate the effectiveness of this technique. DOI: http://dx.doi.org/10.11591/telkomnika.v11i1.1906

Using Bi-level Multi-Objective Programming in Passenger Structure Optimization for Comprehensive Transportation Channel

The economic structure is the lifeblood of national economic development. Passenger structure within comprehensive transportation channel (CTC) is the key to play a higher efficiency and to operate normally of an integrated transport system. This paper analyzes the ideas of PTS optimization within CTC using bi-level planning strategies. And then a bi-level multi-objective programming model is established in this paper, in which the upper level takes the builders and government’s concern into account, such as system efficiency, transport capacity, capital investment. The lower level is a network equilibrium model based on a generalized cost function, while Channel saturation entropy index is introduced in the response function. A particle swarm optimization algorithm is designed to efficiently solve this NP-hard model. Finally, numerical implementations based on Beijing-Shanghai Channel are carried out to account for the performance of our model and algorithm.

U.S. Integrated Transportation Systems in the Future, 2030 to 2050

Intelligent transportation systems (ITS) have focused primarily on systems management. To improve connectivity and safety further, ITS might embrace a more holistic planning approach. Although the future of ITS remains an open question, ITS evolution is closely linked to the social, political, economic, legal, and environmental dimensions. This paper presents the results from four expert workshops: (a) initial steering committee workshop (February 2011), (b) two expert scenario-planning workshops (June 2011), and (c) a final steering committee workshop (July 2011). The scenario planning workshops explored the implications of alternative futures in ITS and incorporated a broad, interdisciplinary approach to develop a long-term transportation vision (2030 to 2050 time horizon) for the United States. Twenty-four experts, who represented diverse disciplines, participated in a series of workshops to envision plausible futures and to assess their effects on the transportation system. By exploring different futures, experts identified opportunities and barriers to the implementation of advanced, seamless transportation systems. Opportunities included the deployment of adaptable, integrated technology and transportation infrastructure to address natural disasters and climate change. The most significant barriers were funding and politics. The experts suggested that financial barriers could be overcome through the use of innovative funding techniques and improved public outreach. Several visions for an integrated ITS approach were then built on the experts' recommendations to address social and environmental challenges in the future. These recommendations included private–public partnerships, distributed implementation models (e.g., localized), and the development of seamless transportation systems to reduce energy consumption, emissions, and road congestion.

Increasing the Safety of Railway Crossings

This article is focused on improving safety at railway crossings and points of active and passive safety features. Following these general safety rules we can reduce or eliminate the risks that increasingly affect the right of railway crossings. The article describes redundant lock crossing time which unfavorably affects the rail crossing accidents and the solution which eliminates this factor. The paper is supported by the VEGA Agency by the Project 1/0188/13 ”Quality factors of integrated transport system in the effective provision of public transport services in the context of globalisation“ that is solved at the Faculty of Operation and Economics of Transport and Communications, University of Žilina.

The Choice between Train and Bus in Durres-Tirana Axis

The Tirana-Durres axis, due to democratic development of the last two decades, represents the richest markets in the Albania’s transportation industry. Internal migrations from rural areas and demographic developments during that period have made this part of the nation’s home of approximately half of country's population. The commercial and residential buildings are extended along the entire distance between Tirana and Durres, the two largest cities of the country, which actually belong to a unified urban centre. However, despite the construction of a highway just a decade ago and the restructuring of some auxiliary roads, the congestion, the flow of passengers and merchandise, and pollution in this axis has become a great concern. Parallel to the highway runs the railway line, which serves passangers moving between Tirana and Durres. For several reasons, ranging from type of trains to investments, the rail system is neglected. Passenger market share of this axis covered by the railway represents only 0.02% of the total demand. In our opinion the solution is correlated to the integrated transport system and one of its goals is dropping the number of vehicles on the roads at the expense of public transportation. Nevertheless, such an aim requires selecting the type of transport with greatest potential. Therefore, a cost-benefit analysis with a wide spectrum of socioeconomic elements is needed. We believe that this scrutiny, which in this paper is treated in the form of a comparison between the rail system and buses, is the proper way to evaluate motor vehicle and a train transport passenger service on Durres-Tirana axis and to choose the best one. In our model we want to stresses the importance of introducing in the Durres-Tirana railway axis new equipment such as diesel multiple units (DMU). These devises serve simultaneously as a locomotive and as a railroad car. Many European countries use DMU in short lines. In such a conception, DMU service extension can serve in Durres-Tirana transport perspective and later on in a gradual expansion in other segments of the Albanian Railway Network.

스마트한 지능형 교통체계 구축을 위한 ITS 관련법령 정비에 관한 연구

In Korea, it is constructing the Intelligent Transportation System(ITS) in according with the ITS project implementation guideline and each ITS standard on the basis of National Integrated Transportation System Efficiency Act. However, only a few ITS project implementation guideline and ITS standard for the exchange of information technologies are not able to construct a smart ITS, without technical regulation for the technical characteristics of the main ITS equipment. Therefore, in this paper, we identify the current status and problems of the legal system and look for the necessity of technical regulation enactment for the smart ITS construction.

Frequency Service Network Design In Freight Transportation Under Integrated Transport System

Nowadays as the integrated transport system is being developed rapidly, how to design service network under the integrated transport system becomes an open issue. Most of the current research literatures in this field fail to integrally consider the transit cost and capacity configuring with different transport modes in the hub node. However, they play important roles for the freight service network design under the integrated transport system. Furthermore, some optimization software such as Lingo and CPlex have been improved significantly recent years. Although their optimization approaches are state-of-the-art, they can’t be carried out directly for reality applications because of the inside disadvantages of the optimization tools. In this paper, we build a service network design frequency model considering the transit cost optimization and capacity configuring with different transport modes. And then, a novel service network design visualization platform is developed based on the C# language of VS2005 and the optimization engine Lingo11. To sum up, this paper not only presents a more effective mathematical model for the problem of freight service network design, but also dynamically uses mature optimization platform to improve the application and practical effect of the algorithm.

Transportation development transition in China

Scientific development is an invaluable asset to a country. Policies and development modes should be carried out based on scientific findings not only in industry, but also in transportation infrastructure construction. Building an integrated transportation system, which is in line with the national requirements of China and supports sustainable socio-economic development, is a key strategic issue related to building a moderately prosperous society and achieving realistic goals of a medium-level developed country. Based on a systematic review of the advances in China’s transportation infrastructure over the last 60 years, this paper explores the main drivers of transportation development, including national policy, transportation structure, investment efficiency, and technological innovation. Analysis shows that China’s comprehensive transportation infrastructure construction since 1949 can be divided into five stages initiated by these drivers, which correspond to four transition modes: policy transition, structural transition, efficiency transition, and technology transition. The transition path of China’s transportation development shows that the dominant factors have changed, and the interval for each transition has shortened. With the implementation of the ‘12th Five-Year Plan’, China’s transportation infrastructure construction is showing some new characteristics and facing a new development transition. Finally, this paper analyzes the trends in transportation development in China and concludes that technological innovation will be the main driving force to increase the transportation supply and service area in the future.

The aim of the transport system is to decrease the level of individual motor transport on sustainable level which is nowadays for many modern states an absolutely necessity.. Such integrated transport system must also take into account the Pedestrian transport, the Cycling transport, the Car sharing and the Car pooling together with adequate infrastructural, organizational and information background which will contribute to the optimal utilization of complex transport systems.

A Flexible Framework for Developing Integrated Models of Transportation Systems Using an Agent-based Approach

Travel demand, traffic flow and land-use models are typically modeled in a decoupled way, i.e. each of the components is modeled separately assuming that parameters related to the other components are fixed. Moreover, the models are often developed by different groups for different contexts, requirements, etc. In this paper we present a prototype of a software framework which allows the user to develop an integrated simulation of a transportation system and also to link additional models to the new simulation in a standardized way. We use an agent-based approach as the basis of such a model. Integrated transportation system models allow model users to overcome the limitations of traditional aggregated, independent transportation models, particularly with respect to sensitivity to behavioral aspects of the travelers. Another requirement, which the software is to satisfy, is the interoperability of models developed in the new framework with legacy models. By interoperability we mean, that any component of the of the model can be interchanged by a legacy software and be used for the integrated simulation. This would allow disparate research groups working on modeling different aspects of a transportation model to plugnplay their models into the framework and test those as a part of an integrated model of an entire system, providing a benefit to researchers, modelers and institutional users of such models.

Reducing the Network Load in CREPEnvironment

This paper presents a car navigation system for a future integrated transportation system forming a component of an Intelligent Transportation System- ITS. The system focuses on the mechanisms of how to detect the current position of each vehicle and to navigate each vehicle. Individual vehicular data is collected using the Global Positioning System - GPS, for location data and it will then be transmitted to a control center via a mobile phone. For the purpose of this paper, the device will be referred to as “Reporting Equipment for current geographic Position” or REP. It is suspected that if a great number of REP equipped vehicles report their positions to the control center simultaneously, there would be a heavy load on the computational communications network (“network”). This paper proposes an algorithm to reduce the network load associated with large numbers of vehicles reporting their position at the same time; if a car skips some reports then it is not possible for the control center to estimate its correct position therefore we need an algorithm that aims to decrease the frequency of the reporting without sacrificing the proper level of accuracy for the position. Compared to periodical reporting, the load effectiveness shows a 50-66% improvement.

Geometro or How to Discover a Valley’s Geomorphology by an Integrated Transportation System in Medellin (Colombia)

Medellin and suburbs form a large city, currently with over 3,200,000 inhabitants. The complex, located in a relatively narrow valley of the Central Cordillera at 6°N, is dominated by plateaux and peaks reaching 3,000 m. The geology is complex, probably formed under the influence of tectonic agents more than two million years ago. The Geometro project was born from the initiative of two regional scientific societies, Parque Explora, a local interactive museum geared to the popularization of science, and the “Colombian Academy of Sciences”. It is designed to characterize the geomorphology of the valley and the local population, from the elevated railway and cable car lines that are included in the project. Geometro is primarily designed for children and adolescents, the main beneficiaries of Parque Explora. After a half-hour oral presentation by a specialist and a set of activities for completion, they will take the aerial train in groups of 15, under the guidance of instructors (geology students) with prior training in the field. They will show the young people a view of the landscape based on the Earth Sciences. A brochure will also be published for the general public, explaining the varied scenery as seen from the metro, from a geomorphological point of view. To complete the project, a second booklet written with scientific terminology, will be produced.
