• Identification of transition curves in vehicular roads and railways

  Publikacja

  • W. Koc

  - Logistics and Transport - Rok 2015

  In the paper attention is focused on the necessity to systematize the procedure for determining the shape of transition curves used in vehicular roads and railway routes. There has been presented a universal method of identifying curvature in transition curves by using differential equations. Curvature equations for such known forms of transition curves as clothoid, quartic parabola, the Bloss curve, cosinusoid and sinusoid, have...

  Mimo podejmowanych wielu działań w zakresie brd na sieci dróg krajowych w Polsce, rezultaty są dalekie od oczekiwań i zadań postawionych przez Krajowy Program BRD GAMBIT 2005. Można by to tłumaczyć dużym przyrostem liczby pojazdów i wzrostem pracy przewozowej szczególnie na drogach krajowych. Ale porównanie ryzyka występującego na sieci dróg krajowych w Polsce do ryzyka występującego na drogach krajowych najbliższych krajów europejskich...

  - IEEE Access - Rok 2022

  In this survey, we analyze the proposals of vehicular communication systems in the context of road traffic management. Starting with the definition of communications between vehicles (V2V), vehicles-to-infrastructure (V2I) and vehicles-to-everything (V2X), we first focus on the requirements and current standards for the Intelligent Transport Systems (ITS), including the maximum communication delay, the communication range and the...

• Driver Fatigue and Road Safety on Poland's National Roads

  Publikacja

  • K. Jamroz
  • L. Smolarek

  - International Journal of Occupational Safety and Ergonomics - Rok 2013

  This paper presents an overview of factors causing driver fatigue as described in the literature. Next, a traffic crash database for 2003–2007 is used to identify the causes, circumstances and consequences of accidents caused by driver fatigue on Poland’s national roads. The results of the study were used to build a model showing the relationship between the concentration of road accidents and casualties, and the time of day. Finally,...

  - Geosciences - Rok 2019

  This paper presents the results of research conducted to develop an automated system capable of determining parameters for horizontal curves. The system presented in this article could calculate the actual course of a road by means of a two-stage positioning of recorded points along the road. In the first stage, measurements were taken with a Real-Time Network (RTN) receiver installed in a research vehicle. In the second stage,...
