Optimization of Addis Ababa LRT stadium station interchange based on microsimulation modeling

Abstract

The research explored integration of transit modes at Addis Ababa's LRT stadium station, to address the city's population growth and consequent strain on the transit system. Lack of modal integration presented challenges to commuters navigating between buses, trains and minibuses. To address the aforementioned, a microsimulation model was conducted on AIMSUN, employing the social force model, to assess 3 options on top of the existing transit system based on transfer times, distances and space availability. The simulated options were further evaluated using a judgement matrix, based on the aforementioned parameters. Results indicated that option B from the simulated options [index value of 0.32], optimized transfer distances and times which improved passenger circulation, achieving acceptable Levels of Service. Hence the study recommended option B for its practicality and future demand considerations, highlighting the need for further research on integrated ticketing systems and modal integration at the network level. The proposed transit setup aimed to enhance passenger transportation efficiency and overall urban mobility in Addis Ababa.
