A Marketing Mix Perspective Muya1, *Francis; Mganilwa2, Zacharia M.D.; Mgaya 3, Prosper L. The Government of Tanzania has invested heavily in Flagship Projects specifically the nation's transport infrastructures to ensure that every part of the country is accessible. These include road and railway infrastructures, especially the Standard Gauge Railway (SGR) which has been heavily invested in recently. Although many strategic options lead to the realization of the SGR project gains in terms of the number of passengers and freight carried, total operating cost, revenues, and high customer satisfaction, a marketing mix lens which involves the application of specific controllable marketing variables, leaves much to be desired. This study involved an intensive review of the literature and interviews with railway experts to determine and assess potential marketing mix benefits during the operations of the SGR project. Data were collected using an interview guide and analysed using the contents analysis technique. The study found that Tanzania Railways Corporation (TRC) must properly align the SGR service and overall corporations’ operations along the marketing mix elements of product, price, promotion, place, people, processes, and physical evidence for the realization of indirect benefits of SGR project. This can be possible through preparing marketing plans, communication, and marketing strategies to integrate the stated elements within the railway organizational setting. 2023-01-01T00:00:00Z http://41.93.71.3:8080/xmlui/handle/123456789/183 Critical Traffic Points for Congestion Dependence on Travel Time Indices in Dar es Salaam, Tanzania 1Mahona, J.,; Mhilu2, C.; John2, G.R.; Kihedu2, J.; Bwire3, H. Critical traffic points for occurrence of traffic congestion in urban road networks depend on travel time-delay indices-based information. The rapid growth of population in urban areas jeopardizes the mobility with the consequences resulting into traffic congestion. Limited studies based on the critical phenomena associated with complex networks, which allow analytically prediction of critical traffic point occurrence of traffic congestion exist. The current work analyzes the same with an objective to elucidate various locations on pre-selected urban road networks to assess traffic flow variations resulting into either low or high vehicle movement. Travel time-delay data were collected using test moving cars. Results indicate that, the critical traffic points that have low travel- delay transition index below 0.70 signifying the jam and crowded traffic flow condition, while with higher values greater than 0.70 indicate free flow phenomena. On the other hand, high congestion index values indicate jam and crowded flow conditions whereas low index values below 0.5 signified free flow conditions. It is thus concluded that critical traffic points indicated to experience jam and crowded traffic flow condition need detailed study on relieving the situations. Major aim is mitigating the propagations of traffic congestion at the respective locations. 2020-01-01T00:00:00Z http://41.93.71.3:8080/xmlui/handle/123456789/182 Energy Harnessing from Bus Rapid Transit Vehicles through Deformable Speed Bumps: a Case of Dar es Salaam BRT System, Tanzania *Mashi, O.K.1 O.K.1; Huseyin2, I.; Mganilwa3, Z.M.D. Bus Rapid Transit (BRT) system is an effective way of commuting passengers in cities. This study investigates possibility of harnessing energy from weights of the bus rapid transit vehicles. An experimental method was used on a testing set consisting of fluid power devices to simulate movements of loaded buses approaching the passengers’ stations. Buses weighing between 7-9 tons and moving at speed range of 10-25km/h were deployed. A hydraulic accumulator was used to store the energy converted from the vehicle weights through a hydraulic system located under a deformable speed bump. The BRT buses used in Dar es Salaam were used in capturing their weights for that purpose. Results indicate that with the speed bump proposed for BRT buses, weights can be converted into energy through hydraulic accumulators. Under minimum operating conditions, the deployed buses could generate 190.67 kJ after every 57 tyre passes over the bumps. 2021-01-01T00:00:00Z http://41.93.71.3:8080/xmlui/handle/123456789/179 Operational Performance of SKF Bearings Carrying Capacity in Tanzania Zambia Railway Authority (TAZARA) Workshops, Dar es Salaam Nangale, J.S.M.B.; Chang’waro, S.K. Proper maintenance and fixing of the right bearings offer a significant cost reduction, longer service life and improve wagon performance. The study examines the operational performance of SKF bearings 16375018-11 carrying capacity at TAZARA Workshops in Dar es Salaam. Wagons fitted with bearings 97720T and 97720KT on 100 mm and 99.5 mm diameter axle journals respectively frequently experienced hot axle failures while in operations. A random sample of 27 serviceable covered wagons (CO) chosen from a population of 70 serviceable covered wagons fitted with 8 number SKF bearings 16375018-11. Findings indicated that SKF bearings 16375018-11 fitted onto the covered wagons improved wagon performance. Results were significantly important to customers and TAZARA in improving services and customer satisfaction. Based on these findings the study recommends that, TAZARA should implement the programme of fitting the rest of the serviceable covered wagons which are in operation with SKF bearings 16375018-11 to improve wagon performance and services to customers. 2020-01-01T00:00:00Z
