Table 12: Classification rules of route 355 in the case study. should be evaluated for different routes. Route 352 is longer and the driving speed on this route is higher and more constant, resulting in higher motor speeds. Therefore, it is recommended to construct different analytical models for Scheme B to summarize the driving indicators. We can draw the following conclusions from the above summaries:  
1. For vehicles on the same route, the same analytical models apply;
2. For vehicles on different routes, different analytical models should be constructed.
