The objective of this research was to examine how personality acts as a mediator in the relationship between reaction time and traffic perception in young adults. Given the increase in the number of road accidents among this age group in the European Union, it is essential to understand the psychological determinants of risky driving behavior. A sample of 60 participants from Poland, Slovakia, and Lithuania was assessed using the Vienna Test System to measure personality, reaction time, time-movement anticipation, and traffic perceptions. The results indicate gender differences in self-control personality factor and motor reaction time, as well as a positive correlation between the sense of responsibility and time-movement anticipation. The proposed model was confirmed, demonstrating that mental stability mediates the relationship between reaction time and traffic perceptions. A driver with high mental stability can react faster to stimuli while accurately perceiving objects in road traffic. This study has implications for road safety policies and practices. Incorporating personality assessments into driver training programs can help develop interventions that target specific personality traits. Furthermore, interventions aimed at enhancing mental stability may help reduce the likelihood of accidents among young drivers. However, this study’s limitations, such as the small sample size and narrow age range, should be considered in future research with other age groups and additional variables that directly impact traffic safety.
本研究的目的是探讨人格在青年反应时间与交通知觉之间的中介作用。鉴于欧盟这个年龄段的道路交通事故数量的增加,了解危险驾驶行为的心理决定因素是至关重要的。来自波兰、斯洛伐克和立陶宛的60名参与者使用维也纳测试系统来评估他们的性格、反应时间、时间-运动预期和交通感知。结果表明,自我控制人格因素和运动反应时间存在性别差异,责任感与时间-动作预期存在正相关。结果表明,心理稳定性在反应时间与交通感知之间起中介作用。心理稳定度高的司机对外界刺激的反应更快,对道路交通中物体的感知也更准确。本研究对道路安全政策和实践具有启示意义。将人格评估纳入驾驶员培训计划可以帮助开发针对特定人格特征的干预措施。此外,旨在提高精神稳定性的干预措施可能有助于减少年轻司机发生事故的可能性。然而,本研究的局限性,如样本量小,年龄范围窄,应该在未来的研究中考虑其他年龄组和其他直接影响交通安全的变量。

This paper presents new functionalities for systems weighing vehicles in motion, which result from the integration of various measurement technologies and the use of a precise registration and data processing system. The utilized registration track provides accurate measurements of basic vehicle parameters such as axle load and vehicle speed and makes it possible to determine the location of the vehicle passing the weighing station, calculate the width of the tire tread, and detect twin (double) wheels. A key functionality is the assessment of the reliability of the measurement, taking into account, among other factors, vehicle movement dynamics and the ambient conditions during the measurements. For this purpose, additional measurements of road surface temperature and wind speed and direction were introduced. The technological solutions used and the proprietary data processing algorithms are described. Tests carried out to verify the effectiveness of the proposed algorithms and to assess the significance of the influence of the isolated factors permitted confirmation of the validity of the proposed solutions.

Noise from cars is one of the main sources of harmful pollution. In the presented paper, an octave frequency band analysis is conducted according to standard methods of external and internal noise measurement. Experiments at different speeds, with three types of cars—conventional gasoline (GV), hybrid (HEV) and pure electric (BEV)— were carried out on two types of pavement—damaged coarse-grained and smooth finegrained asphalt. The results show variations in external and internal noise levels vs. speed in different octave bands. At each speed, a spectral analysis was done. The diagrams with results show changes in noise level vs. speed and the positions of noise maximums. Regression models for the octave spectrum at different speeds and pavements are developed.

The aim of the study is to present the changes in the vehicle dynamics that occur in connection with the use of various fuels that power the engine. The article presents the effect of gaseous fuels being mixtures of LPG and BioDME on the flexibility of the vehicle. In previous studies, not much attention has been paid to the problem of changing the performance of the vehicle with the use of various fuels supplying the engine. It is a new approach that allows to determine the advantages and disadvantages of using alternative fuels, including mixtures using BioDME. The study was conducted for a four-cylinder SI engine with a displacement of 1.6 dm3, installed in a passenger vehicle. The mixture of LPG and DME was assessed, and the results compared to the parameters obtained for the LPG-powered engine. Received results have been made it possible to determine changes in the value of the engine flexibility for selected engine loads and various DME shares in the mixture. The thesis that DME can be considered as an activator of the combustion process and may have an impact on the vehicle dynamics is confirmed.
该研究的目的是介绍与使用为发动机提供动力的各种燃料有关的车辆动力学变化。本文介绍了液化石油气和生物二甲醚混合气体燃料对车辆灵活性的影响。在以前的研究中,没有太多关注随着供应发动机的各种燃料的使用而改变车辆性能的问题。这是一种新的方法,可以确定使用替代燃料的优点和缺点,包括使用生物二甲醚的混合物。该研究是针对安装在乘用车中的排量为1.6 dm3的四缸SI发动机进行的。对LPG和DME的混合物进行了评估,并将结果与LPG动力发动机获得的参数进行了比较。接收到的结果可以确定选定发动机负载和混合物中各种DME份额的发动机灵活性值的变化。二甲醚可以被认为是燃烧过程的激活剂,并可能对车辆动力学产生影响。

This paper presents a method for the precise diagnosis of a diesel engine in an agricultural tractor based on the analysis of efficiency changes and parameters characterizing the process of fuel-air mixture preparation. We proposed that the technical condition be identified based on available data from the engine controller, as this enables the implementation of precise online diagnostics of an agricultural tractor. The method was verified using the original cycle, during which we simulated several engine defects leading to a change in conditions and quality of the processes of creating and burning the fuel/air/flue gas mixture. In the paper, we justified the selection of the points at which the engine parameters were measured, as they provide the most information and allow for efficient identification of damage. These results indicate the possibility of damage identification without the use of the diagnostic cycle in the operation of operator-driven vehicles and autonomous vehicles.
本文在分析燃油-空气混合物制备过程中效率变化和参数特征的基础上,提出了一种农业拖拉机柴油机精确诊断方法。我们建议根据发动机控制器的可用数据来确定技术条件,因为这可以实现农业拖拉机的精确在线诊断。该方法使用原始循环进行了验证,在此过程中,我们模拟了几个发动机缺陷,这些缺陷导致产生和燃烧燃料/空气/烟气混合物的条件和质量发生变化。在本文中,我们证明了测量发动机参数的点的选择是合理的,因为它们提供了最多的信息,可以有效地识别损坏。这些结果表明,在操作员驾驶车辆和自动驾驶车辆的操作中,在不使用诊断循环的情况下,可以识别损坏。

This research paper aims to study the effect of tram management on traffic fluidity and its impact on car drivers’ behaviors at junctions crossed by trams. The methodology used in this research is based on a mathematical model and an investigation of car drivers. The first step is to analyze the data of annual travelers’ attendance and assess the number of trams offered and needed in operation to respond adequately to the factual demand. The second step proceeds to show how the previous results of the trams’ fleet influence traffic jams. That is, this step identifies how the number of trams used in operation blocks other motorists and reduces traffic flow capacity at junctions. Finally, the purpose of the questionnaire is to determine car drivers’ opinions of the causes of traffic congestion at junctions and understand how this phenomenon affects their behaviors. The outcomes demonstrate that tram management is ineffective because there is a considerable gap between the annual offered tram fleet and the actual one needed according to the real statistical data. The high number of trams utilized is the leading cause of traffic congestion. Furthermore, this situation disturbs the control of traffic lights at common intersections. Unfortunately, this outcome is the main reason for drivers’ poor behavior, as 75.20% of car drivers are always stressed. These issues have intensified traffic jams in several junctions along the tram line. The article recommends some solutions to improve tram management and traffic fluidity to avoid the substandard behavior of car drivers at junctions.
本研究旨在研究有轨电车管理对交通流动性的影响及其对有轨电车交叉口汽车驾驶员行为的影响。本研究中使用的方法基于数学模型和对汽车驾驶员的调查。第一步是分析年度旅客出勤率数据,评估运营中提供和需要的有轨电车数量,以充分满足实际需求。第二步是展示有轨电车车队先前的结果如何影响交通堵塞。也就是说,这一步骤确定了运营中使用的有轨电车数量如何阻碍其他驾驶者并降低路口的交通流量。最后,问卷的目的是确定汽车驾驶员对路口交通拥堵原因的看法,并了解这种现象如何影响他们的行为。结果表明,有轨电车管理是无效的,因为根据实际统计数据,每年提供的有轨电车车队与实际需要的车队之间存在相当大的差距。大量使用有轨电车是造成交通堵塞的主要原因。此外,这种情况干扰了普通十字路口的交通信号灯控制。不幸的是,这种结果是司机行为不佳的主要原因,因为75.20%的汽车司机总是有压力。这些问题加剧了有轨电车沿线几个路口的交通堵塞。文章提出了一些改善有轨电车管理和交通流动性的解决方案,以避免汽车司机在路口的不合格行为。

An algorithm for optimizing the routes of a set of vehicles used for the collection and removal of municipal solid waste in a metropolis is proposed. The algorithm eliminates the problem of applying heuristic methods for multi-agent optimization, which is NP non-deterministic polynomial-time-hard. The application of the algorithm leads to a guaranteed exact solution. Through the application of restrictions on the carrying capacity of vehicles, the size of the input matrix representing the transport network can be reduced to an adequate size. This process uses statistical information about the filling levels of container waste bins. The algorithm is applied to an example of two megacities. The shortest routes are built for different numbers of points (from 12 to 72) on the route. The dependence of the total mileage on the number of involved vehicles is studied.

Actions related to the improvement of the safety of disabled road users have multiple levels and are burdened with problems related to the collection and proper analysis of road incidents. A meta-analysis of databases could provide a better understanding of the causes of these events and prevent them in the future. Currently, residual information on participants of road accidents can be found in the Accident and Collision Record System; the data are analyzed by the Polish Road Traffic Observatory and submitted to the International Road Traffic and Accident Database and the Community Road Accident Database. In connection with the above, an article was prepared containing a propaedeutic review of research materials to date, as well as domestic and foreign databases constituting the diagnostics of the research area. An international literature search was also conducted on accidents involving people with disabilities. The findings indicate the need to collect and expand information about disabled participants of road incidents, fill this gap in databases, and systematize them as the starting material for the development of remedial actions.
与改善残疾道路使用者的安全有关的行动有多个层次,并承担着收集和适当分析道路事故的问题。对数据库进行荟萃分析可以更好地了解这些事件的原因,并在未来预防它们。目前,道路交通意外参与者的剩余资料可在意外及碰撞纪录系统中找到;这些数据由波兰道路交通观察站进行分析,并提交给国际道路交通和事故数据库和社区道路事故数据库。关于上述情况,编写了一篇文章,其中载有对迄今为止的研究材料的宣传审查,以及构成研究领域诊断的国内外数据库。还对涉及残疾人的事故进行了国际文献检索。调查结果表明,需要收集和扩大有关道路事故残疾参与者的信息,填补数据库中的这一空白,并将其系统化,作为制定补救行动的起始材料。

Urban transport plays a massive role in the proper functioning of cities [1, 2]. Prioritisation of public transport [3] is an attempt to fight growing traffic congestion, which has a noticeable impact on people’s comfort of living, especially in large cities [4-6]. Shaping the road environment to improve the quality of functioning of public transport means that the management of urban infrastructure cannot cause difficulties. The continuous execution of construction works in Wroclaw has forced the ordering party to introduce temporary, and often complicated, traffic organisation solutions. The primary goal is to ensure the most efficiency for public transport users while maintaining the smoothness of private transport. This article presents solutions to temporary tram traffic organisation used in Wroclaw. The frequency and effects of the applied solutions were analysed using examples of completed and planned tram investments in Wroclaw. The reasons for the applied solutions and possible directions for further analyses were considered.
城市交通在城市正常运行中发挥着巨大作用[1,2]。公共交通的优先化[3]是为了应对日益严重的交通拥堵,这对人们的生活舒适度产生了显著影响,尤其是在大城市[4-6]。塑造道路环境以提高公共交通的运行质量意味着城市基础设施的管理不会造成困难。弗罗茨瓦夫建筑工程的持续实施迫使订购方引入临时的、往往是复杂的交通组织解决方案。首要目标是确保公共交通用户的最高效率,同时保持私人交通的畅通。本文介绍了弗罗茨瓦夫临时有轨电车交通组织的解决方案。通过弗罗茨瓦夫已完成和计划的有轨电车投资实例,分析了应用解决方案的频率和效果。考虑了应用解决方案的原因以及进一步分析的可能方向。
