  • Innovative Research Into Road Restraint Systems

    Publikacja

    - Journal of KONBiN - Rok 2019

    Key to understanding the needs and building road infrastructure management tools to prevent and mitigate run-off-road accidents is to identify hazards and their sources which are a result of wrong design, construction, installation and maintenance of road restraint systems [1]. Building such tools requires advanced studies with field tests, simulations and models to demonstrate the effects of selected parameters on road user safety...

  • Poroelastic Road Surfaces - State of The Art

    Publikacja

    - Rok 2018

    Poroelastic Road Surfaces (PERS) constitute a specific group of pavements containing a great amount of crumbled rubber. In most cases rubber aggregate constitutes about 20% of the mixture (by weight) and a polyurethane resin is used as a binder. As a result, PERS is characterized by a much higher elasticity than asphalt and a high porosity typical for drainage pavements. Due to this, tire/road noise is greatly reduced and on top...

  • Pedestrian Safety in Road Traffic in Poland

    Publikacja

    - IOP Conference Series: Materials Science and Engineering - Rok 2017

    Every third road accident in Poland involves a pedestrian as a participant or, most of the time, a casualty. Pedestrian accidents are usually the result of complex situations and the outcome of a number of factors related to driver and pedestrian behaviour and road infrastructure. Safety depends largely on how well the traffic condition is perceived and on visibility in traffic. The paper presents the results of analyses of methodologies...

This new modern zone of the city centre was destroyed like the rest of Gdańsk in the end of World War Two and had not been reconstructed as a result of de-Germanization of the Recovered Territories....

  • Solid road environment and its hazards

    Publikacja

    - MATEC Web of Conferences - Rok 2017

    Accidents that involve vehicles departing the road tend to have very high severity, as they often result in the vehicle hitting a permanent obstacle (which can be a ree, a pole, facility pillar, front wall of a culvert or a barrier).
