oa Civil Engineer in South Africa - Roundabouts : a motivation for their use with ARCADY2 as the design tool : technical paper

 

Abstract

The roundabout has been the subject of limited research in South Africa and to date has received little serious attention as an alternative to existing traffic control methods. However, the research into program ARCADY2, permitting the analysis of the roundabout facility in comparable terms (namely capacity and delays) with other forms of intersection control, now provides a useful tool for the traffic engineer to assess the appropriateness of introducing such a facility to the road network. The roundabout is also particularly applicable in a rapidly developing community in terms of cost and safety advantages and further research is motivated to produce a non-computerized method of analysing potential roundabout sites.

Tot op hede is daar nog min navorsing oor verkeersirkels in Suid-Afrika gedoen en dit word nog nie gereken as 'n aanvaarbare alternatief tot bestaande metodes van verkeersbeheer nie. Navorsing met betrekking tot die program ARCADY2, waar verkeersirkels met ander metodes van kruisingbeheer vergelyk kan word (in terme van kapasiteit en vertraging), bied egter 'n nuttige instrument waardeur die verkeersingenieur die geskiktheid van 'n verkeerssirkel in 'n padnetwerk kan evalueer. Verkeerssirkels is verder besonder toepaslik in 'n snelgroeiende gemeenskap in terme van veiligheid en kostevoordeel. Verdere navorsing is nodig om 'n nie-gerekenariseerde ontleding van potensiele liggings van verkeersirkels beskikbaar te stel.
