The purpose of the work is to study the influence of the longitudinally-transverse shift of the cargo’s center of mass on the dynamic loading of the wagon in order to solve the problem of predicting the dynamics and stability of an asymmetrically loaded railroad vehicle. During the analytical simulation, a multibody model of the spatial oscillations of the wagon was used. The differential equations of wagon oscillations are compiled using the d'Alembert principle, while the wagon is considered as a system with 42 degrees of freedom. The work presents the results of analytical simulation of some dynamic processes of interaction of railroad vehicles with the rails on the example of flat wagons. The results of the analytical simulation are presented, taking into account the speed of movement along the curved sections of the railway track. The proposed multibody model "heavy cargo – wagon" makes it possible to analytically determine the dynamic characteristics of the system and ensure the development of such methods of transportation of heavy cargo that meet the requirements of train traffic safety. The application of the obtained results will help improve the running safety of freight wagons and enhance the technical and economic performance of railways.

The light detection and ranging (Lidar) sensor is a remote sensing technology that can be used to monitor pedestrians who cross an intersection outside of a designated crosswalk or crossing area, which is a key safety application of lidar sensors at signalized intersections. Hereupon, the Lidar sensor was installed at the Hillen Rd - E 33rd St. intersection in Baltimore city to collect real-time jaywalkers’ traffic data. In order to propose safety improvement considerations for the pedestrians as one of the most vulnerable road users, the paper aims to investigate the reasons for jaywalking and its potential risks for increasing the frequency and severity of vehicle-pedestrian conflicts. In a three-month time, interval from December 2022 to February 2023, a total of 585 jaywalkers were detected. By developing a generalized linear regression model and using K-means clustering, the highly correlated independent variables to the frequency of jaywalking were recognized, including the speed of jaywalkers, the average PET of vehicle-pedestrians, the frequency of vehicle-pedestrian conflicts, and the weather condition. The volume of vehicles and pedestrians and road infrastructure characteristics such as medians, building entrances, vegetation on medians, and bus/taxi stops were investigated, and the results showed that as the frequency of jaywalking increases, vehicle-pedestrian conflicts will occur more frequently and with greater severity. In addition, jaywalking speed increases the likelihood of severe vehicle-pedestrian conflicts. Also, during cloudy and rainy days, 397 pedestrians were motivated to jaywalk (or 68% of total jaywalkers), making weather a significant factor in the increase in jaywalking.

The main aim of the research was to diagnose drivers' behavior in urban road traffic. It was preceded by careful observation and testing of drivers' behavior in terms of the violations assumed to be observed. It was taken into account, inter alia, aspects such as failure to comply with road signs and signals, behavior at the rail-road crossing, or offenses occurring in the pedestrian-driver relationship. During the observations, the assumption was to capture negative behaviors of drivers, but each time attention was also paid to positive behaviors related to road culture. The analysis of the results allowed the researchers to identify the most common mistakes made by drivers. This can help not only to better enforce regulations at selected measurement sites but also lead to improved education about these specific violations.

Main requirements for rolling stock design and organization of the operating system are determined by membership in a certain transportation category for which such a transportation facility is designated. Thus, a specific feature of rolling stock operation is considered to the maximum extent, and functional correspondence with stated tasks is ensured. The significant disadvantage of the existing structure of rolling stock traffic is the necessity of time-space agreements of passenger traffic due to the necessity of shifting different transport types with the minimum time consumption. The solution to such an issue can be found in the development and use of a universal (multifunctional) integrated transport system. The list of issues arising during the creation of a multifunctional transport system can be funnelled into two groups: social and economic and organizational and technical. The first group is social and economic and shall conceptually solve issues of the multifunctional system feasibility for certain urban settlement conditions (conglomerate of urban settlements). The second group consists of organizational and technical issues. This study proposes to eliminate certain material issues in the sphere of suburban and urban traffic by the infrastructure improvement with the significant traffic increase and fluctuations.

The paper considers the vessels operating on carriages of bulk cargoes to get the maximum profit for the shipowner as his main goal. The items in search are the long-term contracts of affreightment with some clauses indicated as indeterminate values, that can be described using a range of values. It leads to a range of voyage indicators. The vessels’ deployment for getting the maximum profit depends on the market situation that is to say possible changes in vessels' time-charter rates and freight rates. This paper presents the mathematical model, based on the fleet and volumes of carriages under a set of contracts of affreightment during the due time. It includes the necessity for the commitment fulfilment by owned and time-chartered vessels and takes into account possible changes in freight rates for cargoes carriages. The presented numerical example demonstrates the opportunity for practical implementation of the model.

Shunting stations play an essential role in ensuring the proper functioning of the railway transport system. The proper organisation of their work allows trains to be dispatched on time and compensates for delays in other areas of the railway network. This paper presents a method for evaluating the technological process of wagon processing at shunting stations based on the author's formulation of evaluation measures and using a simulation model developed in Flexsim. A variant computational example was developed to verify it and demonstrate its capabilities. The method has many applications in assisting decision-makers in organising shunting station operations, adapting the shunting station layout to the tasks or identifying bottlenecks.

The study assessed passengers’ satisfaction with the services of the Lagos Shuttle Train Services in Lagos, Nigeria. Two types of train, the Mass Transit Train (MTT) and the Diesel Multiple Unit (DMU), were covered. Using multistage sampling, 246 passengers were surveyed. It was found that the DMU passengers had higher socioeconomic profiles; the overall condition of the DMU was also better. Further analyses reveal that passengers’ satisfaction differed for the train types: the MTT passengers were more particular about the operational environment, while the DMU passengers were concerned with both physical characteristics and the operational environment. Generally, passengers were satisfied with accessibility, coverage, fare, safety at station and onboard, security at station, and security of luggage; however, the Lagos Shuttle Train Services was found wanting on several key indicators. Recommendations are proffered towards enhancing the service quality of the Lagos Shuttle Train Services.

This paper presents the results of research conducted among 100 local government units performing the duties of road network administrators, i.e., administrators of municipal roads (AMR), county roads (ACR) and those operating within the boundaries of cities with county rights (ACCR). The aim of the research was to identify and assess management problems related to the implementation of statutory measures related to the protection and development of respective road networks. A hypothesis was formulated about the existence of statistically significant differences between the AMR, ACR and ACCR groups, which was verified by quantitative analysis of the data obtained from the online survey. They were analysed and interpreted using the SPSS package and using measures of descriptive statistics, the correlation coefficient and the Kruskal–Wallis test by ranks. The results of the study indicate that the difficulties of providing and maintaining an efficient road network pavement, as well as the challenges of developing draft financing plans for the construction, reconstruction, and rehabilitation of the road network, are currently the main points of focus for all road administrators. The lack of statistical significance of intergroup differences was observed in the vast majority of measurements. The exceptions to this were the differences that occurred in the total number of difficulties reported, which were greater among the members of AMR and ACR than ACCR, as well as the differences related to the implementation of measures undertaken for the maintenance of roadside greenery, which were more onerous for ACR.
