Abstract

This paper presents a comprehensive analysis of path loss prediction models for V2I communication in urban environments, focusing on the impact of non-line-of-sight (NLOS) conditions. Field tests conducted in Bologna, Italy, provided a dataset encompassing four distinct NLOS scenarios. Linear regression and random forest (RF) models were trained and evaluated using meticulously prepared data. Our findings demonstrate the superior performance of the RF model in capturing complex data relationships, as evidenced by lower RMSE, MSE, and MAE values compared to both the linear regression and the standard 3GPP model. Furthermore, the application of a Kalman filter significantly enhanced the RF model's accuracy, achieving near-zero error levels in certain scenarios. In contrast, the 3GPP model exhibited limited improvement, revealing its inadequacy in accurately modeling path loss under complex urban conditions. This research underscores the potential of advanced machine learning techniques, like RF, combined with noise reduction strategies for achieving highly accurate and reliable path loss predictions for V2I communication systems.
