Seat allocation problem in public transportation

One of the problems in public transportation is the vehicle scheduling problem (VSP), which can reduce the bus company cost and meet the demand of passengers’ minimum waiting time. This paper proposes an ensemble differential algorithm based on particle swarm optimization (abbreviated as PSOEDE) to solve the VSP. In PSOEDE algorithm, the mutation process is designed by dividing the original process into two parts: the first part combines the PSO operator with the improved mutation strategy to enhance the global search ability, while the second part is to randomly select two mutation strategies (i.e. random learning and optimal learning) to improve the diversity of population. In addition, the random selection methods of the parameters and crossover strategies are proposed and applied in the total PSOEDE algorithm. The effectiveness and superiority of the proposed PSOEDE algorithm in dealing with the VSP are verified using the simulation experiments and six comparison algorithms.

In this paper, a multi-objective scenario based mathematical model is presented for the capacitated hub location problem in public transportation considering economic and investment aspects. Three objective functions are regarded in the presented mathematical model. The first one aims to minimise the total costs considering the possibility of investing the unused budget at each period. The second one aims to minimise the total processing time in the hub network at each period. The last one aims to minimise the maximum distance between each pair of origin-destination nodes in the network. To solve the model, three multi-objective meta-heuristic algorithms are developed, namely S metric selection evolutionary multi-objective optimisation algorithm (SMS-EMOA), multi-objective imperialist competitive algorithm (MOICA) and non-dominated sorting genetic algorithm (NSGA-II). Finally, developed algorithms are compared to each other based on several comparison measures using a relatively novel statistical approach.

With the accelerating industrialization and urbanization in China, the pressure on resources and environment is serious. To promote development of low carbon, to alleviate the pressure on resources and environment, improve the quality and efficiency, developments in a new direction are being conducted. Rail transit as a public transport system is an important part of urban transportation, called aorta. Low carbon economic development is the most effective booster for the public transport system. Rail transit has several advantages namely environmental protection, energy saving, “green traffic”. A vigorous development in rail transit consequently promotes the development of effective ways of using low carbon and also improves the ability of testing and aids in government's control in urban transportation system. At present, rail transport priority strategy is chosen as the consensus for urban development in nearly thirty cities has been implemented. Since 2006 Xi'an subway construction has been in full swing and was began after the fourth anniversary of the first line. For nearly six dynasties the geographical center of China was Beijing and Shanghai, Xi'an has been approved as a center. A third country as an international metropolis would become the future “triangle”. for the development of metropolis circle and super speed the prospect of the rail transit as public transport is required. This is essential for passengers that are 50% of the population. The rail transit system can certainly make Xi'an, the third international metropolis in the next 10 years. All that is to be followed is the Chinese practice of urban rail transit construction. Subways and light rails reflect the current high science and technology development level, and solve the fundamental problem of urban public transportation. Xi'an subway's sustainable development from being a historical city to a future metropolis has important significance.

We present a game-theoretic model for the line planning problem in public transportation, in which each line acts as player. Each player aims to minimize its own delay, which is dependent on the traffic load along its edges. We show that there exists a line plan at equilibrium, which minimizes the probability of delays of the transportation system. This result is achieved by showing that a potential function exists. Numerical results using close-to-real world data in the LinTim framework clearly show that our method indeed produces delay-resistant line concepts.

One of the biggest challenges for modern metropolises is the problem of public transportation. Barriers to the development of urban transport, the expansion of private vehicles, congestion of beehives, traffic jams, parking problems, and the negative impacts of transport on the environment are causing an increase in interest in shared micromobility. Electric scooters are one of these innovative solutions. This article aims to construct a model for the acceptance of electric scooters among students. The authors employed the technology acceptance model, and used the SmartPLS 4. Program to reconstruct the model. The basis of the model was a CAWI survey on a sample of 442 students. On this basis, the study verified the hypotheses on the relationships between the factors influencing the acceptance of electric scooters: demographic characteristics, perceived usefulness, ease of use, attitudes towards this solution, and behavioral intentions.

Social sites on the World Wide Web allow increased sharing of ideas and problems. Such online networking includes the ability to report public transport problems and get support for campaigns to improve specific aspects of public transport. One site that offers such a facility provided access to its data on problems that were reported over a 13 month period. These were assessed and comparisons were made to see if those campaigns that got the most support were inherently different to the campaigns that received little support, and to investigate the types of problems that were reported online. Whilst definitive answers cannot be given, there are some suggestions that come out of the analysis and the overall impact on improving public transport accessibility and usability is discussed.

Denpasar city is the center of government, trade, education, tourism and various services are indicators of changes in land use, density, movement, and high population, impact on economic improvement, social culture and transportation activities, especially traffic activity. Incriesed activities are followed by an increase in private vehicle usage, which causes transportation problems to become more complex. Therefore, transportation system planning especially in terms of transportation is an urgent thing to do. One of the important transportation systems planning to help solve the transportation problem is the planning of public transportation arrangement. Public transport routes in the Denpasar city have not spread evenly to serve the potential demand for public transportation, such as in the area of South Denpasar for example, there is no public transport routes that serve the community to conduct student activities, public transportation, so that necessary to study the potential demand of public transport, especially on Jalan Raya Sesetan corridor in South Denpasar. The service of reliable public transport is solution to create an effective, efficient and economical route in the utilization of road space and fuel consumption. The objective of providing public transportation which effective, efficient and economical will be achieved if the characteristics of users around the planned service corridor mainly concern the potential of public transport demand is known. Characteristics along the service corridor include the number of family members, the number of workers, the number of students, the number of potential trips, the number of vehicles owned, the monthly family income, the interest in the use of public transport. The result shown the average number of population in the service corridor is 21431 in which all villages have an average N value greater than the value of R (R = 20), thus fulfilling in public transport service, while the number of passengers is 17543 movements.

New Cities Subway, Virtuous Trials or “Routes Tortuous”?

The accuracy of travel time prediction is not only decided by the state of the current journey but also affected by that of the transfer journey. This paper focuses on the transit transfer problem of urban public transport and aims to improve the performance of multi-route bus travel time prediction. In this paper, two kinds of infect factors, which are macro infect factors and local infect factors, are defined. Then, a pre-processing approach is proposed to construct a travel chain, which is used to compensate the shortage of raw data set. Multi-route bus travel time is divided into four parts, which are travel time of the current driving segment (CDS), bus stop dwelling time module, stop-stop travel time, and transfer point waiting time. A parrel processing architecture, which includes four learning blocks, is designed to fulfill the prediction process of the above four time parts. The classic LSTM model is used to predict the CDS travel time and transfer point waiting time. An improved DA-RNN model, the MDARNN model, is proposed to predict the bus stop dwelling time module, stop-stop travel time. Moreover, a real-time traffic flow model is used to calibrate the prediction time of all four sub-models. Experiment results prove the validity of the proposed methods.

Machine learning (ML) solutions have been proposed to make public transportation more attractive. Works that employ ML in bus transportation focus on various problems, such as travel time prediction or passenger flow prediction. These solutions look to improve elements of transportation services, such as the availability of information on passengers’ travel time and the reliability and regularity of the service. An analysis of the solutions proposed in the literature for public transportation by bus can reveal opportunities for data scientists and transportation professionals, and highlight problems that have been only slightly explored. In addition, mapping information about modeling these solutions (e.g., types of data produced by devices on the transportation network, which can be used in modeling a solution) could help beginner data scientists develop public transportation solutions. Transportation professionals can benefit from an overview of possible transportation solutions to improve transportation problems and direct government agency efforts to implement these solutions. This paper presents a survey of ML-based solutions for public bus transportation and details the modeling of these solutions (e.g., data types, ML algorithms). In addition, the problems tackled in the literature are categorized into four themes, and the solutions proposed to deal with them are schematized, highlighting problems that are little explored.
