Oznakowanie poziome dróg i ulic - wybrane problemy, perspektywy rozwoju

Celiński I.

Inżynieria Ruchu Drogowego

2013

Nr 1

16-23

W artykule omówiono wybrane problemy oznakowania poziomego dróg i ulic w warunkach polskich. Wskazano pewne charakterystyczne mankamenty stosowania oznakowania poziomego. Dotyczy to zwłaszcza braku stosowania w polskiej sieci drogowej pewnych sprawdzonych rozwiązań - powszechnie spotykanych na świecie. W podsumowaniu przedstawiono perspektywy rozwoju tego obszaru inżynierii ruchu drogowego.

The article discusses the selected issues of surface marking of roads and streets in Polish conditions. Some specific shortcomings in the use of road surface marking have been pointed out. This concerns particularly the lack of some well-proven solutions on the Polish road network - common in the world. Summarizing, the perspectives of the development of this field of traffic engineering have been presented.

Do Children Have One Third Less Peripheral Vision Than Adults?

Hancock P. A.

International Journal of Occupational Safety and Ergonomics

2004

Vol. 10, No. 2

191--195

The following report is a case study example of how problematic information can invade and percolate through the literature on forensic human factors and ergonomics. Initially, a highly doubtful assertion was used to bolster an argument made in a legal case of wrongful death. The assertion was supported through reference to a number of cited works. When the trail of evidence was pursued, however, it became clear that diverse citations had all branched from one, single, original and doubtful source. The fundamental issue, whether children have one third less peripheral vision than adults turns out to be much more complex than the original, simplistic spatial conception suggested. The case study illustrates the importance of ascertaining original citations and is yet another example of the frustration that often accompanies forensic activity where financial and legal concerns frequently over-ride the fundamental search for knowledge.
