    Opis:
    . This study proposes the use of multi-criteria decision models (MCDM) for transportation mode-route choice decisions. This method is beneficial when trips' microdata are unavailable. Route-mode choice decisions were investigated for three public transportation modes (buses, railways, and airlines) in the post-China Pakistan Economic Corridor (CPEC) investment in Pakistan Railways (PR) for a link between Peshawar and Karachi. TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) was used for the mode choice decisions and a hybrid model of AHP (Analytical Hierarchy Approach) – TOPSIS was used for the route choice decision ML-1 link of PR. This study concludes that rails were the best mode of transportation in post-CPEC investment. Furthermore, route 3, linking Karachi to Peshawar via Lodhran, Multan, and Miniawali, is the best route connection among the four considered routes.

    Opis:
    For transport planning and policy-making, visualising the relationship among attributes; gender, education, occupation, age with travel pattern and mode choice is important. Household Interview Survey (HIS) is one of the major inputs in transport study which contains information about travel and demographic characteristics. From the analysis of 28,235 households in Dhaka city, this study represents the social demographic characteristic of Dhaka city based on the household survey. It was found that 89.79% of dwellers make double trips in a day and the trip rate per trip maker is 2.16, where 14% of total trips are generated at morning peak time between 7 to 8 am. The bus is the most preferable mode share and its contribution is about 35%. The scenario changed in a multimodal trip case and walking was the domination mode share with about 45% of total trips. Vehicle ownership had a vital rule in particular mode choice, especially in car and motorcycle household ownership case. Significant impact on travel patterns and mode choice criteria was found with gender, education, occupation, age, household income, trip purpose and time and vehicle ownership, which can help to formulate the strategic plan to solve the transport-related problem in Dhaka.

    Opis:
    This article presents the establishment of a model of understanding the access mode and railway station choice of Slovenian passengers. Therefore, a model has been designed to predict the determination of existing decision making preferences of railway users about the access mode and railway station choice with a stated preference survey and face to face method. The target group in the survey were railway passengers in the suburban environment that use the rail for work and school purposes. The total number of respondents was 412. The survey showed that most passengers access the railway station with car (60,2%), by foot (26,2%), with public transport (bus – 8,3%) and with bike (5,3%). Average distance to the station is 4,9 km, average time of access is 10,5 min. Upon exit most passengers walk to the final destination (84,5%), use the public transport (bus – 14,1%), car (1,2%) or bike (0,2%). Average time from exit of the train to final destination is 13,1 min, average distance is 1,58 km.

    This paper models a proposed system that has the potential to transport baggage. It makes use of a modal choice model to examine how effective the system would be if implemented. The introduction of a baggage collection system would increase the number of passengers using public transport which would be good for the environment. The specific location of the study was Tyne and Wear and a journey from North Shields to Newcastle International Airport was chosen for the analysis. With the introduction of a new utility equation that could analyse mixed-mode travel, a baggage collection hub based in Newcastle upon Tyne city centre offered a significant number of users provided that the cost of the system was either covered in the travel ticket or provided by the airport or airline free of charge. This dedicated baggage collection system would be very expensive to introduce due to the massive amounts of work that would be required to set up the system, however, its ridership would be large therefore it could potentially recoup the development costs.
    W artykule przedstawiony został proponowany model transportu bagażowego. Wprowadzenie systemu zbierania bagażu zwiększy liczbę pasażerów korzystających z transportu publicznego, co w efekcie przyniesie dobre skutki dla środowiska. Do analizy wybrana została lokalizacja pomiędzy Tyne i Wear oraz podróż z North Shields do Newcastle International Airport. Analizowany system zbierania bagażu byłby bardzo kosztowny do wprowadzenia ze względu na ogromne ilości pracy, która jest niezbędna do prawidłowej konfiguracji systemu. Jeśli jednak liczba przejazdów byłaby duża, możliwe jest potencjalne odzyskanie kosztów rozwoju systemu.

    Social media are deemed influential in making decisions and seeking advice. Due to their explosive growth as critical channels for information, their content can trigger a place visit, a change of transport mode or destination, or plans’ cancellation. The main objective of this paper is to investigate the influence of social media on users’ activity and mobility planning. Responses of 738 participants in a digital survey were used to formulate ordinal regression models. The developed models determine the contribution of users’ demographic characteristics, travel characteristics and social media usage to mobility decisions after using social media as a source of information. These decisions were expressed in two dependent variables; (i) the impact of social media use in activity and mobility planning; (ii) the impact of the proposed transport mode by social media information, on mode choice. Analysis of the results indicated that the models, which considered all the characteristics together, could better predict the two variables.

    This paper reviews current systems that either transport baggage or have the potential to transport baggage, as well as proposed systems, before modelling some of them in a modal choice model to examine how effective they would be if implemented. It was hoped that the introduction of a baggage collection system would increase the number of passengers using public transport which would be good for the environment. The specific location of the study was Tyne and Wear and a journey from North Shields to Newcastle International Airport was chosen for the analysis. The system proposed is compared to an existing systems known as InPost and Virgin Bag Magic. It was found that for the average passenger in North Shields, a system based on the way InPost operates would offer the greatest utility. However, with the introduction of a new utility equation that could analyse mixed-mode travel, a baggage collection hub based in Newcastle upon Tyne city centre offered a more significant number of users provided that the cost of the system was either covered in the travel ticket or provided by the airport or airline free of charge. This dedicated baggage collection system would be much more expensive to introduce compared to the InPost system as the infrastructure to run the InPost system is already in place, however, the ridership of the newly proposed system would be much larger therefore it could potentially recoup the development costs.

Spodziewano się, że wprowadzenie systemu zbierania bagażu zwiększy liczbę pasażerów korzystających z transportu publicznego. Takie rozwiązanie byłoby dobre dla środowiska. Miejscem wykorzystanym do analizy był obszar pomiędzy Tyne i Wear, podróż z międzynarodowego lotniska North Shields w Newcastle. Zaproponowany system został porównany do istniejących systemów znanych jako InPost oraz Virgin Bag Magic. Stwierdzono, że dla przeciętnego pasażera z North Shields, system oparty na działaniach InPost jest najbardziej użyteczny. Jednak wraz z wprowadzeniem nowego systemu, który może analizować podróże w trybie mieszanym, skoncentrowanie 142 D.C. Reece, M. Marinov zbierania bagażu z siedzibą w Newcastle dałoby dostęp znacznie większej liczbie uczestników, pod warunkiem że koszt systemu zostałby zawarty w bilecie podróży lub podróż z lotniska oferowana byłaby bezpłatnie. Wprowadzenie dedykowanego systemu kolekcjonowania bagażu byłoby znacznie droższe w porównaniu z systemem InPost, jednak biorąc pod uwagę to, że liczba przejazdów korzystających z zaproponowanego systemu byłaby znacznie większa, koszty poniesione na wprowadzenie systemu mogłyby zostać zwrócone w niedługim czasie.

    Opis:
    The determinants of mode choice of interregional transport of fish, which is highly perishable, vastly differ from that of other commodities. These determinants are to be identified to improve transport efficiency. A questionnaire survey of shippers is used to collect the data. Highly correlated observed variables are combined to form four latent factors by factor analysis to reduce the errors in modelling. Logical relations among the component variables of latent factors are perceived, and mathematical formulations are used to estimate new variables. It is found that transportation costs and shipment weight contributes to factor 1, while distance contributes to factor 2. However, transportation costs are associated with distance and shipment weight. Thus, the variable, transportation cost per q-km, is estimated. Survey respondents' attitudes are also incorporated into modelling by including qualitative factors obtained by the factor analysis of shippers' preference ratings. A latent class analysis confirmed the existence of heterogeneity among shippers. Misrepresentations of effects occur in modelling if the heterogeneity in the data is not considered. No studies have found the best combination of observed variables, latent factors, estimated variables, and qualitative factors, considering shippers' heterogeneity in freight mode choice. Hence, this study is done to find the optimum modelling strategy. Modelling revealed that models built with estimated variables outperformed those built with latent factors. Including qualitative factors along with observed variables and estimated variables showed further improvement. However, the model that includes observed variables, estimated variables, and qualitative factors considering shippers' heterogeneity is the best. It was found that the mode selection behaviour of different latent classes of shippers is distinct. A mode shift from road to rail could be achieved by lowering transportation costs and increasing speed, reliability, and safety for fish transport. Expanding roll on-roll off facilities, dedicated freight corridors, parcel trains, refrigerated containers, and piecemeal service by rail promote a mode shift from road to rail and reduce energy usage.

    In recent years, the transport mode choice of students of higher educational institutions has become a subject of increasing interest. Investigating the modal choice of students, who form a considerable section of the population, is crucial for sustainable urban transport planning and understanding the quality of life of students. Reviews of previous studies have indicated that hilly cities in less developed countries are neglected in transportation studies. The present paper investigates the travel behaviour of non-local, off-campus college students in Aizawl – a fast-growing hilly city in northeast India. The study found that transport mode choices are influenced by interrelated factors, including socio-economic background, demographic, availability of transport mode and location of housing. It was also found that walking and public buses are the most preferred modes of commuting among the studied college students. Female students who rent houses near their colleges are more likely to walk than their male counterparts. On the other hand, male students belonging to high-income families tended to travel by private vehicles from their residences, which are located relatively far away from colleges. The study argues for the enhancement of the intake capacity of residential hostels inside the campus to improve the growing transport problem of off-campus students in the city.

    Opis:
    The Covid-19 pandemic has significantly affected the economic and social spheres of all countries. Restrictions introduced to reduce the risk of transmission have changed the structure of population movements. The impact of these restrictions on the characteristics of intercity travel is still an understudied problem. Based on the analysis of statistical data and the results of questionnaires, the article assesses the impact of pandemic restrictions on population mobility in the Western region of Ukraine and changes in the distribution of passenger flows between different modes (bus, rail, private transport, joint travel). In 2020, the volume of passenger traffic in the region decreased by an average of half compared to the previous year. The decline is sharper for rail passenger transport compared to the bus transport. For more developed railway networks, the impact of the pandemic on passenger traffic is more pronounced. Quarantine restrictions have also increased the share of own car travel. According to research, the distribution of intercity trips between modes is influenced by the age and sex of the traveler. During the pandemic, users of transport services who travel with children under the age of 14 choose private transport to travel more often than those who travel alone. The degree of influence of the above factors on the distribution of modes depends on the length of the trip. The application part of the work presents the results of modeling passenger flows of the studied region in the software environment PTV Visum. It was found that at the beginning of the quarantine restrictions the number of intercity trips decreases sharply. As the duration of restrictions increases, the rate of decline in mobility decreases. These data can be further taken into account when planning the work of transport enter-prises and meeting the population`s demand for travel. The practical application of the study results is that the identification of trends in the mobility of residents of the studying region depending on the impact of pandemic restrictions allows you to predict the mode and type of vehicles used. Based on these data, you can determine marketing strategies for the development of certain modes and directions of transportation.

    Opis:
    This paper explores the new research challenges for forecasting urban goods demand by rail. In fact, the growing interest to find urban logistics solutions for improving city sustainability and liveability, mainly due to the reduction of urban road accessibility and environmental constraints, has pushed to explore solutions alternative to the road. Multimodal urban logistics, based on the use of railway, seem an interesting alternative solution, but it remained mainly at conceptual level. Few studies have explored the factors, that push actors to find competitive such a system with respect to the road, and modelling framework for forecasting the relative demand. Therefore, paper reviews the current literature, investigates the factors involved in choosing such a mode, and finally, recalls a recent modelling framework and hence proposes some advancements that allow to point out the rail transport alternative.
    Artykuł analizuje nowe wyzwania badawcze związane z prognozowaniem transportu dóbr w miastach z wykorzystaniem kolei. Rosnące zainteresowanie znalezieniem logistycznych rozwiązań miejskich, które miałyby poprawić zrównoważony rozwój miasta oraz zwiększyć jakość życia mieszkańców, spowodowane jest zmniejszeniem dostępności do dróg miejskich oraz ograniczeniami środowiskowymi. Wspomniane aspekty wymogły rozpoczęcie badań nad innymi rozwiązaniami niż wykorzystanie dróg. Multimodalne rozwiązania logistyki miejskiej, oparte na wykorzystaniu kolei, wydają się być interesującym rozwiązaniem alternatywnym, jednak pozostają głównie tylko na poziomie koncepcji. W badaniach analizowano czynniki, które skłaniały do odnalezienia konkurencyjnego dla drogi systemu i ramy modelowania dla prognozowania rzeczywistego popytu. W artykule zaprezentowano ocenę bieżącej literatury, badanie czynników wpływających na wybór kolei oraz przypomniano niedawne ramy modelowania. W pracy zaproponowano również nowe rozwiązania, które pozwalają na wskazanie transportu kolejowego jako alternatywy do transportu drogowego.

    Opis:
    The propulsion system of multi-mode ships cause many problems of proper the choise of propulsion system elements and theirs arrangement in the design process. This system has to fulfil at least two inverse demands. It ought to make possible efficient ship shift (transit mode) from the port to the off shore work place and return to base, to ensure a ship survive at sea in the worst sea condition possible on that sea area and to fulfil conditions of dynamic positioning accuracy (stationkeeping mode) at specified bad state of the sea - not to stop the ship work for long time. The dynamic positioning systems require multi-element ship propulsion application. The fulfilment, all required possibilities and accuracy of ship positioning by chosen propulsion system specified in the project data, is the most important project problem to obtain the minimum investment costs. The redimensioning of propulsion system, increasing the number of thrusters and theirs possibilities gives the benefits in dynamic positioning accuracy, but increases the investment costs.
