Application of root cause analysis techniques to enhance passenger safety during boarding onto multiple-unit rolling stock

Applying the Ishikawa and the Bow-Tie techniques to identify root causes in a real-life passenger injury case while boarding a suburban train is examined, the effectiveness of existing control measures (barriers) is analyzed, and new ones are proposed in the article. The issue of enhancing passenger safety in suburban railway transport remains relevant despite the general downward trend in the number of railway incidents in Ukraine.

Assessment of the accident rate coefficient at pedestrian railway crossings

The object of the study is pedestrian railway crossings, which are specially designed pedestrian paths across railway tracks intended to ensure the safe passage of pedestrians over railway infrastructure, including areas outside of official level crossings. An analysis of statistical data found that in the first three quarters of 2024, the percentage of injuries and accidents caused by moving railway rolling stock involving unauthorized individuals increased by 12.7 % compared to 2023.

Justifying the structure of the improved mechanism for manual control of motor vehicles’ pedals

Due to the challenging military situation in Ukraine, the demand for tailored and flexible pedal control systems for individuals with physical disabilities is especially important. Standard pedal configurations often fail to meet the specific needs of drivers with limited mobility, making vehicle operation both difficult and potentially unsafe. The development of specialized manual control devices, such as hand-operated pedals or adjustable foot controls, is crucial for ensuring that these drivers can manage their vehicles with accuracy and safety.

Impact of pedestrian flows on traffic delays before roundabouts

The paper examines a roundabout located in a residential district of Lviv city. The area has many attraction points, so traffic and pedestrian flow volumes are large. All approaches to the roundabout have unsignalized pedestrian crosswalks, three of which lack safety islands. Field studies were conducted on peak and off-peak periods, collecting primary indicators of traffic and pedestrian flows. Traffic flow delays were determined on the approaches to the roundabout under existing traffic conditions with the help of the PTV VISSIM software.

Regularities of the traffic lane change by the driver when interacting with car-obstacle

The paper presents the results of experimental studies of drivers` behavior when interacting with obstacles caused by parked vehicles. Today, parking cars on two-lane streets is a significant problem for drivers while driving as it creates obstacles. Drivers need to spot a parked car in time and perform a lane change maneuver. It affects the trajectories of vehicles and the functional state of the driver. The driver needs a certain amount of time to maneuver, which consists of the reaction time, the decision to change the lane, and the execution of the action.

Influence of mountain traffic conditions on the functional state of a bus driver

Ensuring the transport process requires proper interaction of all parts of the system "driver - car - road - environment" and its subsystems. In this case, the driver is often a "weak" component of the system, and his actions can reduce the level of road users` safety. It should be noted that the reliability of the driver can be considered as the probability of his trouble-free and error-free operation, as well as the proper level of his regulatory mechanisms functioning.
