idm_equilibrium_gap — DRIVE traffic op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.idm_equilibrium_gap(v, *, v0: 'float', T: 'float', s0: 'float', delta: 'float' = 4.0) (to call the implementation directly, import drivetraffic; drivetraffic.idm_equilibrium_gap(v, *, v0: 'float', T: 'float', s0: 'float', delta: 'float' = 4.0); from the registry, opsdrive.get("idm_equilibrium_gap"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

IDM の平衡車間 s_e(v) = (s0 + v T) / sqrt(1 − (v/v0)^δ)(0 ≤ v < v0)。

Δv = 0 で `idm_accel` = 0 と置いて解いたもの(s* = s0 + vT)。v → v0 で発散する(希望速度では車間は要らない

= 前が無限に遠い)。a, b に依らない。

門: 先行車が一定速度のとき `idm_platoon_simulate` が収束した車間と rtol 1e-6 で一致。

Raises `ValueError`: v < 0 または v ≥ v0。
