Abstract: In order to analyze the delay at main-and-auxiliary bus platforms under the interference of non-bus vehicles, such as ride hailing vehicles, this paper constructs a delay model based on impact time and flow reduction. Building upon traditional delay models, this delay model considers the movement characteristics of buses. First, delay models for both linear and bay platforms are developed, considering the micro-behaviors of buses at stops influenced by non-public vehicle parking. Second, a comprehensive delay model for main-auxiliary platforms, accounting for non-bus vehicle stops, is established using the movement patterns at main-and-auxiliary platforms and the single-platform delay models. The feasibility of the model is verified using VISSIM software, with the mean absolute percentage error (MAPE) as a validation index. Finally, a case study is conducted at a typical bus stop in Jiaozuo City, Henan Province, examining the suitability of different main-auxiliary platform types under varying outer lane traffic flows and percentages of buses affected by non-bus vehicle stops (α) . The results show that under the interference of non bus vehicle stopping, the maximum errors of the impact time and the flow reduction models for main-and-auxiliary platforms are 33% and 7%, respectively. The bay-bay parallel and series main-and-auxiliary platforms cause the least delay, with the impact time reduced by up to 70% and flow reduction increased by up to 30%, which is applicable for scenarios where the outer lane traffic flow exceeds 400 pcu⋅h-1 or α is greater than 0.1. The study demonstrates that the proposed delay model is suitable for calculating platform delays under the interference of non-public vehicles, and the main-and-auxiliary platform design provides a reference for the design and optimization of bus stops with non-bus vehicle stopping.
