Fusing crash data and surrogate safety measures for safety assessment: Development of a structural equation model with conditional autoregressive spatial effect and random parameters

•Propose a new safety performance measure—Risk Status (RS), by fusing crash data and surrogate safety measures (SSMs).•Develop a structural equation model to capture the interrelationship among RS, crashes, SSMs, and risk factors.•Discuss the potential of using RS for safety assessment. Most existin...
