Abstract


The requirements of sustainable transportation system are safety, affordability, accessibility and convenience. A sustainable transportation system connects various transport modes to enhance efficient movement. It is environmentally friendly and economical. The non-motorized transportation (NMT) may offer safe, efficient, economical and sustainable movements required if integrated with the transportation system. Walking begins and ends trips taken by public and private transportation means. The origin and destination of a journey cannot be completed except NMT is employed. However, NMT as a mode of transportation is yet to be adequately utilized to achieve sustainable transportation in the city of Tshwane. The main aim of this research is to determine the optimal transportation means by integrating NMT into the journey between Ga-Rankuwa and Rosslyn. The travel pattern obtained from trip studies of BMW staff between Rosslyn and Ga-Rankuwa was studied and juxtaposed with the integrated transport plan (ITP) and municipal housing survey (MHS) of Tshwane. A linear programming method called simplex technique was utilized for the determination of trip duration and trip cost from the origin-destination study results. The movement records of the BMW staff was optimized. A sensitivity analysis was conducted on the model and the results were evaluated. The result showed that taxi was the most patronized mode of transportation by the BMW staff between Rosslyn and Ga-Rankuwa corridors. The result also showed that the average trip cost of BMW workers from home to office is R18.47. Integration of cycling as a mode of transportation for short distance trips created 3 more trip patterns. When cycling was integrated to the rail transportation, 36% of the transportation cost was reduced. This work also showed that the subsisting trip method may still be used by less than 45% of the BMW staff while more than 55% of the staff may utilize the integration of cycling and train from home to office and vice versa. This research recommends that similar investigation should be done to other routes of economic importance in the City of Tshwane in order to encourage the integration of cycling into transportation from one place to another.
