In a (1+n)-dimensional Lorentz--Finsler manifold with N-Bakry--Émery Ricci curvature bounded below for N∈(n,∞], using the Riccati equation techniques, we established the Bishop--Gromov volume comparison for the so-called standard sets for comparisons in Lorentzian volumes (SCLVs).We also established the Günther volume comparison for SCLVs when the flag curvature was bounded above.
