Abstract: The bus dwell time refers to the time spent waiting for the passengers to get on and off the bus at the platform, which is the main reference factor for the operation scheme of the bus system and the setting of bus stops. Bus dwell time presents different trends in different periods of time in densely populated areas such as central urban area and central business district. A generalized bus dwell-time model was established, based on the waiting time outside the bus stop, the time when the bus accelerates to enter the bus stop, the actual stop time of the bus at the bus stop, the total number of passengers getting on the bus, the total number of passengers getting off the bus and other factors. The change trend of the bus dwell time in different traffic hours in the downtown area was studied. Finally, the quantitative analysis of the bus dwell time distribution in different station environments of Nanning public transportation system was carried out. The research shows that the bus dwell time at morning peak is obviously larger than that at the noon peak and evening peak, which can help decision-makers of public transportation system to make reasonable development strategies and improve the overall service level of public transportation system.
