Bus System

Sudden passenger demand at a bus stop can lead to numerous passengers gathering at the stop, which can affect bus system operation. Bus system operators often deal with this problem by adopting peer-to-peer service, where empty buses are added to the fleet and dispatched directly to the stop where passengers are gathered (PG-stop). However, with this strategy, passengers at the PG-stop have a long waiting time to board a bus. Thus, this paper proposes a novel mathematical programming model to reduce the passenger waiting time at a bus stop. A more complete stop-skipping model that including four cases for passengers’ waiting time at bus stops is proposed in this study. The stop-skipping decision and fleet size are modeled as a dynamic program to obtain the optimal strategy that minimizes the passenger waiting time, and the optimization model is solved with an improved ant colony algorithm. The proposed strategy was implemented on a bus line in Harbin, China. The results show that, during the evacuation, using the stop-skipping strategy not only reduced the total waiting time for passengers but also decreased the proportion of passengers with a long waiting time (>6 min) at the stops. Compared with the habitual and peer-to-peer service strategies, the total waiting time for passengers is reduced by 31% and 23%, respectively. Additionally, the proportion of passengers with longer waiting time dropped to 43.19% by adopting the stop-skipping strategy, compared with 72.68% with the habitual strategy and 47.5% with the peer-to-peer service strategy.

At the end of 2019, the whole world and Indonesia were shocked by the emergence of the new coronavirus disease 2019. It has been more than a year since this disaster struck. The number of victims around the world has reached more than one hundred million with the death toll of more than two million people. Various efforts have been made to prevent the spread of this virus, one of which is social restrictions so that it has an impact in various areas of human life. One of the impacts is the missionary service which usually carries out social and face-to-face interactions. By using qualitative research methods with a literature review approach, observation, and interviews and then describing, this study will provide answers and solutions for mission service strategies during the Covid19 pandemic. The results of this study found answers to mission services online or online. By utilizing internet networks and social media, the gospel can still be preached despite social restrictions. Facebook, YouTube, Instagram, and Tiktok are some social media applications that can be used for mission services during the Covid-19 pandemic, through these applications this news can be presented in the form of writing, audio, and video which are shared via social media. This strategy, with its strengths and weaknesses, provides a great opportunity to continue working on the Great Commission of the Lord Jesus during the Covid-19 pandemic.
