Rapid Safety Assessment Tool for Non-Conventional Roadway Designs and Emerging Technologies: Innovative Artificial Intelligence Application

This research proposes a proactive road safety assessment for non-conventional designs and emerging technologies in Wyoming utilizing traffic conflict analysis. Furthermore, the innovative assessment methodologies will provide detailed observation and analysis of driving behavior, trajectory interpretation, and conflict measures. These methodologies will be based on computer vision applications utilizing recorded video data. It is suggested to apply the proposed methodologies on locations within Wyoming that received complaints from residents and/ or according to WYDOT recommendations. The objectives of this research include the following: (1) Conduct a hotspot analysis to determine the crash prone intersections (2) Provide a quick nonintrusive traffic and turning movement counts at intersections as a temporary traffic count methodology. (3) Perform a conflict analysis to provide insights about the causes that lead to Critical Safety Events (CSE) (i.e., crashes and near crashes). (4) Develop an automated conflict analysis system to evaluate the performance of roadway facilities with a focus on intersections/ interchanges. (5) Investigate driving behaviors that mostly influence CSE. (6) Assess the traffic safety performance of intersections and roadway facilities using conflict and crash prediction models using predicted conflicts. (7) Evaluate the effectiveness of applied countermeasures at intersections. (8) Conduct a sensitivity analysis to assess the safety performance of proposed countermeasures under different traffic demand levels and various weather conditions. The demand levels will be determined based on average annual growth rate multiplied by the number of years to the current year demand. (9) Determine the applicability of the conflict analysis to assess CAV applications. (10) Provide WYDOT with a new framework of safety assessment techniques which is more appropriate for evaluating emerging technologies.
