A sustainable transportation system is safe, affordable and accessible. It connects different modes of transportation in order to achieve efficient movement. A sustainable transport system is one that is economical and friendly to the environment. All trips in private and public transport begin and end with walking. Non-Motorized Transport (NMT) plays a key role in completion of any journey from origin to destination. However, this mode of transport is not used optimally to enhance sustainable transport, especially where public transport is concerned. The main objective of the research was to evaluate an optimal combination of transport modes for trips made by BMW employees residing in Ga-Rankuwa north of Pretoria, in order to reduce cost of transport. The travel behaviour of BMW employees was investigated by first studying secondary data on the Municipal Household Survey (MHS) and Integrated Transport Plan (ITP) of Tshwane City. The secondary data was supplemented with primary data which was sourced by interviewing the BMW’s human resources department and conducting trip studies between Rosslyn and Ga-Rankuwa. The trip pattern of workers of BMW was evaluated to know the origin-destination, journey period and transportation cost of the trips. The movement patterns of the BMW workers were grouped into four categories. The patterns were subjected to optimization using linear programming which included the subsisting movement pattern. The trip patterns developed were based on relevant literature. The BMW workers’ movement from home to work was optimized. Their movement to work constituted a transportation challenge or problem; and was solved using simplex technique, a linear programming approach. The model was subjected to a sensitivity analysis and the results were analysed. It was found that the most patronized transportation mode for the trips between Rosslyn and Ga-Rankuwa was taxi. It was further discovered that BMW workers expended R18.47 averagely on movement from home to work through taxis. The recognition of cycling, a means of movement within short distances, allows for additional trip patterns as available options for commuters. The integration of cycling as a feeder system to trains resulted in 36% trip cost reduction for the commuters. The research revealed that while less than 45% of the employees may continue to use the present scenario, more than 55% of the employees may use a combination of cycling and trains. The study suggested that similar work should be done to cover other economic and important routes in order to encourage the use of cycling as a link to other transportation modes in other industrial areas of the City of Tshwane.
