Strengthening road safety in the face of the enormous development of the automotive in recent decades is crucial. The safety benefits of automated vehicles are paramount. Automated vehicles have the potential to remove human error in road traffic, which will help protect drivers and passengers, as well as pedestrians and bicyclists. The carried-out forecasts are pioneering for...
Urban transport systems operate according to fixed, strict timetables, which requires high timeliness and technical readiness of the fleet. Therefore, this article proposes a detailed study of the punctuality of the public transport system using a multiple regression model for the main modes of transport (trams, buses, and Warsaw Metro). The analysis made it possible to go beyond...
A problem of car insurance frauds usually refers to reporting non-existent car crash circumstances to acquire the funds required for a car repair. However, the problem is not limited only to this kind of costs. Recently, numerous damage claims connected with spine trauma caused by rear-end collisions have been reported. These are the so-called whiplash injuries caused by a rear...
Air transport, like every economic branch, strives for development. Air traffic is growing dynamically, which means that the natural environment is increasingly being polluted each year. Therefore, entities operating in the air transport sector should care for the environment. One of these entities - airports - introduces many restrictions for aircraft with high CO2 (carbon...
The transport accessibility of cities decreases with the increase in road traffic. Planners, traffic engineers, and road managers are looking for solutions that will reduce congestion on city streets without limiting transport accessibility to the city center. The article presents an overview of solutions used in Poland and abroad that aim to encourage people who travel by car to...
The paper deals with a comparison of shocks (values of acceleration coefficients and inertial forces) of two types of vehicles (T-810 and T-815 MK IV) during transport experiments on a motorway. The measurement was performed using an OM-CP-ULTRASHOCK-5 three-axial accelerometer with a datalogger and calibration certificate. The goal of the paper is to accept or reject a...
In general, it can be presented that winter road maintenance costs are rising due to increasing mobility, rising of salaries, and technological needs. For this reason, it is necessary to bring innovations into these processes. The greatest space is in the area of weather forecasting, which is a trigger for maintenance activities in the form of reducing black ice or snow removal...
The paper describes selected research achievements into the effect of weather on road traffic from the perspective of various combinations of traffic characteristics and meteorological conditions. Studies to date have focused on different traffic parameters and changes in them as a consequence of weather variety. In making a comparative analysis, researchers identify the optimal...
The purpose of this article is to present the authors' own software for predicting changes in the density and directions of traffic flows and to compare overall results of research on transport accessibility with the results returned in the study of transport accessibility conducted with the software (isochronic accessibility). Developed for research purposes, the authors...
The article presents the results of research of the Gwarek 1200 belt conveyor. The work aimed to determine the possible benefits of changing the type of rollers used. It was expected that the change of the rollers from N-type to C-type will reduce the costs of energy consumed by the conveyor drive system. This part of the research was carried out in a hard coalmine at the level...
Marine passenger ports are integrated into the transport systems of cities and regions today. If there are sufficient developed mathematical forecasting models in the class of polynomial models, probability series, and a number of others, then the models describing the influence of the external environment on ferry market are not sufficient. The developed scheme of interaction...
This article presents the results of the analysis and assessment of the effect on transport of programs supporting housing investments in the context of transport demand management. The evaluation of the presented programs confirms the dependence of inconsistent spatial planning policy and the growth of transport needs. The effects of the programs have been analyzed in detail...
Land-sea transport chains constitute a key part of the Europe’s economy, as a significant part of its trade is carried out using sea transport. Transport, storage, or delivery processes carried out within these chains are characterized by specified economic and technical efficiency, which often does not take into consideration the external costs these processes generate...
This article assesses the effect of factors, such as the number of sidings, the number of station holds, and the occurrence of transit traffic on the volume of freight transport on railway lines in Poland. The volume of freight transport on a railway lin as expressed by the operational work done by freight trains running on this line and the transported freight mass by them. Most...
This article discusses the issue of seaport competitiveness. This is one of the most important issues in port studies. Conducting a port competitiveness analysis focuses on comparing components of port competitiveness for selected ports or terminals. First, a comparative analysis of selected seaports was performed in the article, followed by a detailed analysis of selected...
In this study, the methodological foundations of the technology for the local reduction of chemical pollution from vehicles were improved through the use of twolevel suction units and guide plates of various lengths installed on the nozzles of the suction devices. A program has been developed for the numerical calculation of the carbon monoxide concentration field for evaluating...
Mortality caused by road accidents is a significant problem for most countries, including Poland, where approximately 2,900 people die each year, and another 37,359 are injured. Research in this area has been conducted on a large scale. One of the most important elements is the evaluation of factors leading to fatalities in road accidents, which is also the goal of this article...
The article is devoted to the issue of the negative effect of delays in the movement of special rescue vehicles on the effectiveness of their mission. The dependence of the area of fire on the delay of the arrival of firefighters using a fire-rescue vehicle is shown. The cascading graph of route options of special vehicle movement to the place of an emergency call is given. The...
In this investigation, the problem of moving object detection - without any knowledge - is classified. It describes a technique that will allow real-time localization with usage of IR sensors. The proposed algorithm is simplistic, and in the future, it might be implemented into any vehicle, premium or entry level. It is guided by AI that must calculate its next moves in the blink...
While choosing an electronic payment system intended for an immediate communication of a user (passenger) with an electronic terminal of a service provider (carrier), it is necessary to respect system parameters of presented technologies (NFC, EMV, and ABT). The methodology of choosing an electronic payment system within public transport may be divided into three steps as follows...

The intersection of a public road with a railway line in one level, called a rail-road crossing, is a particularly dangerous place due to the traffic flows crossing it. The regulations give absolute priority to a rail vehicle over a public road user; in addition, significant differences in the masses and speeds of moving vehicles require traffic regulation consisting of adequate...
Despite the rapid and continuous progress in the construction of vehicles and accompanying improving road infrastructure, the road safety issue remains very serious. Especially, it concerns intersections and road junctions where nearly 30% of road accidents take place. The paper is focused on a new intelligent path displaying suport system to be installed on intersections of...
Desert sand is subject to deflation, which during the construction and operation of railways in the sandy desert leads to the filling of the railway track with sand and erosion of subgrade. To prevent this phenomenon, the surface of the sand is fixed with a binder, which is sprayed onto a deflated surface. The penetration of the working composition of the binder due to the...
