A Paper titled Conflict angle analysis at multilane roundabouts using naturalistic vehicle trajectory data from UAVs authored by Apostolos Anagnostopoulos, Apostolos Ziakopoulos, Fotini Kehagia, Athanasios Theofilatos, Pantelis Kopelias and Nikolaos Eliou has been published in Traffic Injury Prevention. This Paper aims to enhance current knowledge by employing Surrogate Safety Measures (SSMs) to investigate conflict angles at modern multilane roundabouts in Greece using naturalistic vehicle trajectory data collected via Unmanned Aerial Vehicles (UAVs). Detailed vehicle trajectory data from four modern multilane roundabouts in Thessaloniki, Larissa and Volos were collected through UAV video recordings and processed using vehicle tracking software, with a mixed-effects Beta-regression Model (BRM) with site-varying random intercepts applied to model conflict angles. The findings suggest that the location of conflicts within the roundabout significantly affects the conflict angle, and that site-specific characteristics have a substantial impact, emphasizing that roundabout safety performance can vary by location.
