The introduction of PBS for heavy vehicles in South Africa was first identified in the National Overload Control Strategy as a potential concession of a proposed Self-regulation initiative. In August 2004 a PBS committee was established to investigate PBS and the following initial tasks were identified: 1) develop a PBS strategy; 2) review the status of PBS in other countries; and, 3) initiate pilot projects to demonstrate the potential benefits of PBS. Two concept designs (a truck / trailer and a B-double) were initially developed and considered. The truck / trailer concept vehicle was selected, and after a number of iterations a satisfactory vehicle design was achieved. At a total mass of sixty-seven and a half (67.5) ton and length of twenty-seven (27) meter the new combination satisfies the PBS performance standards considered and delivers a payload increase of fifteen (15) percent. By contrast, the baseline vehicle with lower payload capacity was not able to satisfy several PBS performance requirements
