A case study using typical cold-region data is conducted. Finally, we discuss the effects of individual and combined policies, and parameter variations on the electrification process. The results indicate: i) replacing buses with electric ones in cold regions does not significantly increase the life cycle costs; ii) EB price subsidies and annual operational subsidies effectively accelerate electrification, and most policy combinations further reduce social costs; iii) the model can adjust replacement strategies based on case data and parameter changes.

Recent changes in helmet regulations have shifted preferences towards faster vehicles. Furthermore, dynamic pricing strategies, such as adjusting ride or unlock fees, can incentivize the use of less desirable vehicles with lower battery range or aid in user-based relocation. Nevertheless, low-range vehicles are less likely to be chosen, even with incentives.
