Bus rapid transit at isolated vehicle actuated junction using recall and green extension bus priority strategy

Abstract

The mode split of public transportation usage in Johor Bahru has been disappointingly low. This research highlights the concept of public transport implementation to reduce the number of private vehicles on the road in Jalan Bukit Impian, Johor Bahru. Therefore, Bus Rapid Transit (BRT) had been suggested as the alternative to improve public transportation as public transportation is well-known to have high quality of service. The objectives of this study were to determine performance of BRT as well as the financial benefit of different BRT scenarios. Three different BRT scenarios with varying modal split created where scenario 2,3 and 4 consists of 16:84, 38:62 and 46:54 ratio of public transportation to private transportation. The research implements the use of exclusive bus lane and bus priority strategy by recall and green extension method. Average delay time and average travel time was used to assess the performance of the network and the total delay cost is used to assess the financial benefits of BRT implementation. The results. The results were compared between the base case and the BRT scenarios. It was discovered that the implementation of BRT in the study area has no benefits in terms of average delay and travel time. However, in terms of total delay costs, Scenario 4 with 46% public transportation and 54% private transportation has the lowest total delay cost, which is up to 20.43% of savings. It can be concluded that, the objectives of the research in determining the performance and financial benefits of implementing BRT had been fulfilled.
