  • Jobson, AJ (CSIR, 1973)
    A number of rumble installations have been constructed on rural roads in South Africa and although no local accident data are available the provincial roads engineers consider them of value in alerting drives to the need ...
  • National Institute for Transport and Road Research; Transport and Road Digest (CSIR, 1977)
    Rumble surfaces are intermittent short lengths of coarse-textured road surfacings on which vehicle tyres produce a rumbling sound. used in conjunction with appropriate roadsigns and markings, they can reduce accidents on ...
  • Wium, DJW; Ribbens, H (National Institute for Transport and Road Research: CSIR, 1986-02)
    A method is described for setting the speed limit for a particular road section. Several speed limits based on different criteria are described for each of nine traffic and road factors. The most appropriate speed limit ...
  • Kennedy, DA (National Department of Transport, South Africa, 1991-01)
    Relationships of speed vs density, volume and percentage loop occupation are investigated. The effect of differing directional splits in traffic volumes is also examined. A method of determining the Level-of Service of ...

    The road user in South Africa currently experiences a large gap between gravel and paved roads in terms of the serviceability and standards which are applied. Because of the high coasts associated with current paved road ...
  • Division of Roads and Transport Technology CSIR; Jordaan & Joubert Inc. (National Department of Transport, South Africa, 1993-03)
    The purpose of this manual is to provide guidelines on the upgrading of gravel low volume roads to roads and maintenance personnel of road authorities of all sizes. Low volume is, for the purpose of this document, defined ...
  • Skinner, DG (National Department of Transport, South Africa, 1994-02)
    The available data bases for accidents, road geometry (photolog output) and traffic counts were combined and the accident rates determined for two lane, four lane and six lane road categories as well as for 22 geometric ...
  • Semmelink, CJ; Groenewald, M; Du Plessis, E (National Department of Transport, South Africa, 1994-03)
    The report deals with the site investigations in connection with the compaction standards, that is a comparison between actual in situ dry densities achieved compared to specification requirements, for road layer work for ...
  • De Haan, ML; Coovadia, T; De Jager, PJD (SA Department of Transport & CSIR Transportek, 1996-04)
    This publication contains information on all major modes of transport in South Africa. The transport sector is placed in perspective relative to the macro economy and a number of important transport indicators are given. ...
  • Emslie, I (National Department of Transport, South Africa, 1997-03)
    This report presents guidelines to assist local authorities and traffic engineers with a uniform approach to the design and implementation of mini-roundabouts. It is recommended that these guidelines be read in conjunction ...
  • Emslie, I (Department of Transport, 1997-03)
    This report presents guidelines to assist local authorities and traffic engineers with a uniform approach to the implementation of speed humps. It is recommended that these guidelines be read in conjunction with The National ...
