RESEARCH OF THE FACTORS INFLUENCING THE OPERATIONAL PERFORMANCE OF URBAN PUBLIC TRANSPORT

Problem. Currently, there is no universal approach to improve the efficiency of the urban public transport operation. Different methods are used during the estimation of public transport operation cost and the quality of services for the passengers. It makes actual the development of the target function which will allow assessing the carrier cost and passenger expenditures, and therefore find the balance between the interests of these parties of the transportation process. Thus, the alternative to the existing approaches can be created and then used to organize passenger transportation and improve transport enterprise management. Development of this alternative is the actual task as the new target function will open the horizon to improve the methods of organization of public transport operation. Goal. The new approach to optimize the costs of public transport operation needs to be tested for the appropriateness for the planning of passenger service in cities. Methodology. The developed target function was derived as the result of the analysis of the economic and social factors influencing the efficiency of the urban public transport operation. Results. The use of the developed target function allows finding the optimal values of cost components for the passenger and the carrier. Originality. The obtained function to optimize the performance of public transport allows reducing the costs of suboptimal use of vehicles capacity, suboptimal allocation of the vehicles to the routes and the irrational organization of vehicles operating on the routes. Practical value. The results of the research clarify the controlled and uncontrolled parameters of the public transport system operation.

Urban Public Transport

Urban agglomerations (centres with gravitating settlements in the suburbs) are examples of overpopulated urban structure with almost permanent peak load. Selection of public transport is the fundamental issue in planning the expansion of the existing one, or in constructing a new form of urban public transport system. Achieving a higher level of using mass public transport can also be inspired by building intermodal terminals (e.g. bus-train/urban railways/-car). However, apart from the urban railway, funicular, bicycle subsystem and maritime transport should be included as alternative public transport modalities as well. According to the problem described in this scientific paper, the suggested model is that of integration of all forms of public passenger service with a unique organisation, unified payment collection, integrated timetable, all included into a unique information system. The results of research in this paper indicate that the first step of integration of the public passenger transportation implies founding regional transport administration.

Abstract This article presents a detailed description and explanation of the methodology for evaluation of quality public transport criteria in terms of passenger satisfaction. In 2011-2014 this method was applied in an assessment of passenger satisfaction with the urban public transport system in Ostrava. In order to assess passengers’ satisfaction, traffic survey has been chosen utilizing questionnaire and student inquirers. The results achieved by application of the method have been processed to evaluate time accessibility criteria of a public transport system. Time accessibility criteria group (accessibility of stops, waiting for a connection and transferability in the public transport network) evaluates physical and psychological aspects of the passenger during his arrival at the station, while leaving the station, in the course of waiting for a connection and during the transfer. The time accessibility criteria are considered the most significant criteria that impact a passenger’s decision to utilise public transport options.

This study has a special interest in urban public transportation institutional framework in the Klang Valley, Malaysia. The notions for the topic were developed from issues regarding institutional framework in delivering urban public transportation. Although the current urban public transport in Klang Valley has improved, there are still issues concerning the institutional framework. To date, there is no single regulator or agency with the express and overriding responsibilities for strategic management of the public transport system in KlangValley. The purpose of this study is therefore to assess the current urban public transportation institutional and governance framework especially towards urban mobility. To achieve this, the study employs the content analysis and case study method, using the purposive sampling approach for expert interviews in gaining the data from participants of related agencies. It examines the importance of public transportation frameworks and present status of current transport development, as well as the roles of urban transportation agencies involved in delivering urban public transport. Results demonstrated that urban public transportation is delivered through multiple agencies with separate roles, not counting the inconsistency of various policies. Hence, the expectation of this study is to suggest practical approaches to improve the current institutional framework of urban public transportation.

Urban Public Transport

The demand of transport grows along with road traffic. Congestion costs 1% of the GDP of European Union (European Union 2014) and also causes significant emissions of carbon dioxide and other pollutants. This problem could be solved by transfering a part of passengers from private modes of transport to the public transport. But the essential condition is a sustainable development which means the accessibility on equal terms. Therefore, attention to the focus group – people with movement impairements, is neccessary. Since even under ideal conditions some of those people will not be able to use the ordinary public transport services, a special transportation service, called paratransit, should be offered. In this paper the parameters of paratransit as well as their variations are analyzed. Also the wider application possibilities are considered. The aspects of integration of paratransit into the existing system, pottential barriers for the integration and conditions for the integration are highlighted. The main purpose of this paper is to formulate the scenarios for the integration of paratransit into the existing public transport system based on the analysis of the scientific literature and the best practices, which could be used to form a policy of improving the accessibility of the public transport for people with movement impairments. Transporto paklausa nuolat auga, o kartu su ja ir kelių eismo intensyvumas. Spūstys Europoje kasmet sudaro apie 1 % jos BVP (Europos Sąjunga 2014), dėl jų išmetama daug anglies dioksido ir kitų nepageidaujamų teršalų. Ši problema miestuose gali būti sprendžiama perkėlus dalį keleivių iš privataus į viešąjį transportą. Tačiau labai svarbu, kad vykdomi projektai atitiktų tvarios plėtros principus, pagal kuriuos numatomas viešojo transporto prieinamumas lygiomis teisėmis. Todėl būtinas dėmesys tikslinei žmonių grupei – žmonėms, turintiems judėjimo apribojimų. Kadangi dalis tų žmonių netgi esant idealioms sąlygoms negalės naudotis tradiciniu viešuoju transportu, jiems yra būtina specialioji transporto paslauga, vadinama paratransportu. Šiame straipsnyje yra išskiriami paratransporto paslaugos parametrai, jų variacijos. Taip pat analizuojamos platesnės šios paslaugos pritaikomumo galimybės. Išskiriami transportinės paslaugos integravimo į esamą viešojo transporto sistemą aspektai bei potencialūs barjerai ir sąlygos paratransporto paslaugai įdiegti. Šio straipsnio tikslas – remiantis mokslinės literatūros ir gerosios patirties analize suformuluoti paratransporto įdiegimo į veikiančią viešojo transporto sistemą scenarijus, kurie gali būti taikomi formuojant viešojo transporto prieinamumo žmonėms, turintiems judėjimo apribojimų, tobulinimo politiką.

The City

In Muscat, the capital of Oman with over one million inhabitants, urban public transport practically does not exist and the use of private cars is dramatically increasing. As a result, accident rates and traffic congestion, two particularly pressing concerns in the urban area of the capital, have both risen. This situation has focused the concern of public administrations and has led to the urgent need of developing a Public Transport System in the city In order to develop this system in an integrated manner, the plan proposes to unify and organize regulation and management of public transport by creating a public transport authority, headed by the Ministry of Transport and with a very strong involvement of Muscat Municipality. By 2015 only two urban bus lines operate in Muscat, covering a small area of the city–Wadi Adei, Wadi Kabir and Ruwi. Therefore, the plan adopts a conservative approach by proposing the implementation of a comprehensive urban bus network –composed by trunk and feeder lines adapted to the low density of the city- before establishing other high capacity solutions, such as BRT or LRT. A key element of the system is the number of 13,400 taxis and microbuses that represent the only alternative to the 317,000 cars of Muscat. The plan suggests the reorganization and further regulation of the sector to achieve the professionalization of the taxi services and the migration of existing users, part of them to the professionalised taxi services and the other part to the implemented public transport services.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3457

This paper shows the results of an in-depth techno-economic analysis of the public transport sector in a small to midsize city and its surrounding area. Public battery-electric and hydrogen fuel cell buses are comparatively evaluated by means of a total cost of ownership (TCO) model building on historical data and a projection of market prices. Additionally, a structural analysis of the public transport system of a specific city is performed, assessing best fitting bus lines for the use of electric or hydrogen busses, which is supported by a brief acceptance evaluation of the local citizens. The TCO results for electric buses show a strong cost decrease until the year 2030, reaching 23.5% lower TCOs compared to the conventional diesel bus. The optimal electric bus charging system will be the opportunity (pantograph) charging infrastructure. However, the opportunity charging method is applicable under the assumption that several buses share the same station and there is a “hotspot” where as many as possible bus lines converge. In the case of electric buses for the year 2020, the parameter which influenced the most on the TCO was the battery cost, opposite to the year 2030 in where the bus body cost and fuel cost parameters are the ones that dominate the TCO, due to the learning rate of the batteries. For H2 buses, finding a hotspot is not crucial because they have a similar range to the diesel ones as well as a similar refueling time. H2 buses until 2030 still have 15.4% higher TCO than the diesel bus system. Considering the benefits of a hypothetical scaling-up effect of hydrogen infrastructures in the region, the hydrogen cost could drop to 5 €/kg. In this case, the overall TCO of the hydrogen solution would drop to a slightly lower TCO than the diesel solution in 2030. Therefore, hydrogen buses can be competitive in small to midsize cities, even with limited routes. For hydrogen buses, the bus body and fuel cost make up a large part of the TCO. Reducing the fuel cost will be an important aspect to reduce the total TCO of the hydrogen bus.

As an extension of public space, the public transport system in modern society is an arena for cross-group interactions. Uncovering social segregation in public transport space is an essential step in shaping a socially sustainable transport system. Based on 2011 origin–destination flow data for London, we simulate the working flows between each pair of connected tube stations for every occupation with minimised transfer times and travelling hours and calculate the multi-occupation segregation index for all tube stations and segments. This segregation index captures the density and diversity aspects of the working population. The results demonstrate that segregation levels vary significantly across stations, lines, and segments. Transfer stations and tube segments in the city centre do not necessarily have lower levels of segregation. Those stations or segments close to a terminus can also be socially inclusive, e.g., Heathrow. Victoria is the line with the lowest levels of segregation, and Green Park is the most socially inclusive station during commuting peaks. The proposed mapping approach demonstrates the spatial complexity in the social performance of the public transport system and provides a tool for implementing relevant policy with improved precision.
