摘要：
Semi-deterministic modeling with low data resolution requirement and low computation time is always of interest. By conjunctively utilizing the extended Hata model and the Deygout model, this letter presents a hybrid model for viaduct and cutting scenarios of high-speed railway. The proposed model achieves higher accuracy than empirical and statistical models, but uses totally free sources. It can be easily implemented for the network planning, and therefore, it meets the demand for fast development of high-speed railway.
