Research on autonomous vehicles (AV) has made significant progress in the transportation industry in recent years. Currently, the pavement system is not being constructed or maintained to accommodate this new group of vehicles. Pavement is an intricate structure that consists of multiple layers of different materials that influence its behavior under various stresses. The impact of AVs on the pavement system is uncertain. This study adopts a three-dimensional finite element method (FEM) to investigate the behavior of rutting and fatigue distress due to loading the AV wheel in a dedicated lane. The effect of parameters such as the lane width (Lav) and the speed (Vav) of the AVs has been discussed. The findings indicate that the concentration of wheel path of AV traffic on the dedicated lane accelerates rutting and fatigue distress that could reduce overall pavement performance. The simulation results are compared with those of the IITPAVE software.

摘要

Research on autonomous vehicles (AV) has made significant progress in the transportation industry in recent years. Currently, the pavement system is not being constructed or maintained to accommodate this new group of vehicles. Pavement is an intricate structure that consists of multiple layers of different materials that influence its behavior under various stresses. The impact of AVs on the pavement system is uncertain. This study adopts a three-dimensional finite element method (FEM) to investigate the behavior of rutting and fatigue distress due to loading the AV wheel in a dedicated lane. The effect of parameters such as the lane width (Lav) and the speed (Vav) of the AVs has been discussed. The findings indicate that the concentration of wheel path of AV traffic on the dedicated lane accelerates rutting and fatigue distress that could reduce overall pavement performance. The simulation results are compared with those of the IITPAVE software.
