How to overcome the inhibiting factors in BRT Trans Semarang services, namely planning a special route for the Jrakah intersection to the Pedurungan intersection with a length of 12.8 km to improve service and reduce passenger waiting time, as well as improve fleet intervals. While the effectiveness of BRT Trans Semarang service corridor I Mangkang-Penggaron obtained a total average percentage value of 84% in the very good category. The results of the one sample t-test that have been carried out obtained a sig 2-tailed value of 0.000 0.05, indicating that Ho was rejected, so the average value of the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service corridor I Mangkang-Penggaron is not the same with 80.
