A car-following model with stochastic memory effect is considered.
- class="label">•
Empirical evidence is obtained from car-following field experiments.
- class="label">•
Gamma distribution is shown a suitable representation of memory effect empirically.
- class="label">•
General expressions of undamped and stability regions are derived.
- class="label">•
Smaller mean or greater variance of memory effect would enlarge stability region.
