ROAD SAFETY PERFORMANCES FROM MICRO-SIMULATION CONSIDERING AUTONOMOUS VEHICLES OPERATIONS

2019

Introduction of Autonomous Vehicles in road traffic will remove the impact of the human factor from the driver’s decision-making process, and will transform the criteria for road network design, road infrastructure administration, traffic modeling and assessment tools for road safety management. The paper presents a microsimulation-based approach for safety performance evaluation of roundabouts where different percentages of Autonomous Vehicles are mixed with Conventional Vehicles. The simulated vehicle trajectories exported from VISSIM were used as a basis to estimate traffic conflicts through the Surrogate Safety Assessment Model (SSAM) for a sample of European roundabouts. In order to be…
