KPI Definitions
8 key performance indicators for evaluating robotaxi remote operations platforms. Measurable, comparable across operators, and actionable.
MTTR
seconds/minutes · Real-time, report daily
Average time from anomaly detection to confirmed resolution.

| Layer 2 (AI + Human) | < 3 minutes | < 90 seconds |
| Layer 3 (Remote/On-Site) | < 15 minutes | < 10 minutes |
| Overall (weighted) | < 2 minutes | < 1 minute |
AI Autonomous Resolution Rate
% · Daily, report monthly
Percentage of anomalies resolved by Layer 1 without human involvement.
| Category | Target | Stretch |
|---|---|---|
| Early deployment (<6 months) | > 50% | > 60% |
| Operational (6-18 months) | > 65% | > 75% |

False Escalation Rate
% · Weekly review, monthly report
Percentage of escalations where the lower layer could have resolved the anomaly.
| Category | Target | Stretch |
|---|---|---|
| L1 → L2 False Escalation | < 15% | < 10% |
| L2 → L3 False Escalation | < 10% | < 5% |
Missed Escalation Rate
% · Weekly review, monthly report
Percentage of Layer 1 resolutions that should have been escalated to human operators.
| Category | Target | Stretch |
|---|---|---|
| Missed Escalation Rate | < 2% | < 1% |
Passenger Trapped Duration
minutes · Per-event, monthly report
Time a passenger remains unable to exit the vehicle after requesting to do so.
| Category | Target | Stretch |
|---|---|---|
| P50 (median) | < 2 min | < 1 min |
