Abstract:

This study proposed a quantitative approach to evaluate the effects of dwelling buses on the traffic operations of non-motor vehicles at stops in China. The primary objectives of this study were to compare the changes in non-motor vehicle speeds with/without dwelling buses by applying statistical methods; and to develop a generalized event count (GEC) model for traffic conflict prediction and analysis. Data were collected by a unmanned aerial vehicles (UAV) with a visual range of 60 meters at near side, far side, and mid-block stops in China. In order to better understand the changes in speeds of non-motor vehicles at different sections of the bus stop, the area was divided into three sections: upstream area, bus stop area, and downstream area. The results showed that the dwelling buses could reduce the speeds of non-motor vehicles at bus stops. Furthermore, to evaluate the performance of the proposed GEC model, another model based on queuing theory method was used for comparison. According to the results, the GEC model had more accurate and reliable fitted values (with 12.80% of mean absolute percentage error (MAPE) and 0.8442 of R-square) than the compared method (with 18.55% of MAPE and 0.7397 of R-square). Consequently, with the proposed method, it was feasible to evaluate the effects of dwelling buses on the traffic operations of non-motor vehicles at bus stops. Finally, to improve the traffic operations at stops, transportation agencies could consider implementing countermeasures to control the conflicts between dwelling buses and non-motor vehicles, such as reducing bus delay time at stops.
