Abstract

The transport sector of the economy has a substantial impact on the environment through the consumption of non-renewable liquid fuels and the production of gaseous and particulate emissions. Current trends in public attitudes combined with increasingly stringent fiscal constraints are likely to restrict the construction of new road transport facilities to a few isolated projects. The lack of new road capacity, in conjunction with future traffic growth, will increase congestion levels with a concomitant increase In fuel consumption and vehicle emissions. This paper investigates traffic engineering measures such as improvements to traffic signals and intersections, which can be implemented at relatively low cost, to reduce fuel consumption and vehicular emissions of the urban transport sector. An estimate is made of the potential national savings if the proposed measures are implemented in urban areas throughout the Republic.

Die vervoersektor van die ekonomie lewer 'n groot bydrae tot die land se verbruik van nie-herwinbare vloeistofbrandstowwe en gepaardgaande produksie van uitlaatgasse. Hierdie faktore belemmer uiteindelik die natuurlike omgewing. As gevolg van beide veranderende waardesisteme en toenemende druk op die beskikbare fondse, is fisiese uitbreiding van die padnetwerk, op 'n paar uitsonderings na, onwaarskynlik. Die direkte gevolg van verkeersgroei sonder die nodige bykomende kapasiteit op die padnetwerk is groter vertragings en noodwendige hoer brandstofverbruik en dus voertuig-uitlaatgasse. Hierdie referaat handel oor vervoeringenieursmaatreels soos opgradering van verkeersligte en kruisings wat stedelike brandstofverbruik en uitlaatgasse effektief kan aanspreek sonder buitensporige koste. Beramings word gemaak van die potensiele besparings wat kan realiseer deur instelling van die maatreels in stedelike areas landwyd.
