Item An appropriate Bus Rapid Transit System(IJST Publications, 2014-04) Adewumi, Emmanuel Olusegun; Allopi, DhirenBus Rapid Transit (BRT) has been adopted as an improvement on regular bus services through the combination of features like infrastructure changes that resulted in better operation speeds and service reliability. In this regards, it does pose a problem in selecting a BRT that is most suitable for a particular area/region. Hence, this study suggests an appropriate BRT system during in-depth literature review. To be able to select the appropriate vehicle option for a BRT system for a particular area/corridor, the transport demand, coverage/distance to be covered and length of public transport delay due to general traffic condition must be put into proper consideration. In terms of cost implication, median BRT system and kerbside BRT system should be selected over segregated BRT system.Item Determining the best BRT for eThekwini(3S Media, 2014-06) Adewumi, Emmanuel Olusegun; Allopi, DhirenBRT systems are fast becoming part of the South African urban landscape. In the first part of this two-part article, the authors set about defining BRT systems, looking at their history and examining configurations, factors and options.Item Study of drivers’ response time in traffic streams(IJESIT, 2013-05) Adewumi, Emmanuel Olusegun; Allopi, DhirenReaction times of drivers responding to traffic wardens'. signals are important for the design and safe operations of roads. The increased number of road users and pedestrians lead to increasing demands on the facilities and eventual inconvenience and delays. This study evaluated the response time of drivers on the minor leg of Challenge Intersection in Ilorin because of the significance of the minor traffic stream on the capacity analysis or design of traffic merging at the major leg. The method employed was basically manual whereby stopwatches were used to measure the response time of drivers who were unaware of being monitored The response time of each driver in a traffic stream queue was taken in relation to respective positions in the queue. The average response time for the first and consecutive vehicles in stop and move signal are shown in tables 1.0 and 1.1 respectively. It can be deduced that those far behind do not have to see the warden signals before they respond because the brake light of the preceding vehicle will dictate the signalItem Rea Vaya : South Africa’s first bus rapid transit system(ASSAf, 2013) Adewumi, Emmanuel Olusegun; Allopi, DhirenToday, both the public and private transport sectors are facing challenges as a result of an increase in vehicle ownership and the suburbanisation of both firms and residences in the world. In the past, public transport was focused mainly on central areas of cities where high population and employment densities enabled frequent services, high occupancy rates and many routes. As growth is spreading to suburban areas from the metropolitan area, imperative challenges arise for public transport: to increase service in order to better serve commuters and to integrate suburban service with metropolitan service. 1 Public transport must be made more attractive and user friendly in relation to improved service, travel information, reliability, safety and the upgrade of infrastructure such as waiting stations. Cost is an important factor that influences the demand for public transport in relation to the time spent waiting, boarding and alighting from vehicles coupled with the risks and inconveniences involved in those actions. It has also been suggested that commuters and business users board the fastest and most direct routes. 2 Here we comment on the performance and maintenance of the Rea Vaya system – South Africa’s first bus rapid transit system – since its inception
