NHTSA USNCAP INJURY PREDICTOR (GROUP A)

Predicts the seven canonical USNCAP driver-injury metrics (chest deflection, femur peak Z-force, NIJ, neck tension, HIC, neck compression, frontal-barrier star rating) from six pre-test interior geometry inputs. Wraps the Group-A sklearn ml_predict_ersatz model trained on the NHTSA front-impact corpus. Range bounds for every input come from the training run’s own schema. Star rating is rounded + clamped into the [1, 5] USNCAP integer scale before being emitted. Execution is gated on the same NHTSA_CRASHDATA_LICENSE_KEY sitevariable the NHTSA Crashdata Finder uses, so a single d3VIEW-issued key unlocks every NHTSA worker.

Inputs

Label ID Type Default Required Description
Foot rest to X Pre_test foot_rest_to_x_pre_test number 585 Pre-test distance from the foot rest to the X-reference point (mm). In-distribution range [394, 760]; values of 0 or outside the range are rejected as out-of-training.
Brake pedal to X Pre_test brake_pedal_to_x_pre_test number 551 Pre-test distance from the brake pedal to the X-reference point (mm). In-distribution range [367, 629]; values of 0 or outside the range are rejected as out-of-training.
Center to steering wheel hub to X Pre_test center_to_steering_wheel_hub_to_x_pre_test number 70 Pre-test distance from the centre point to the steering wheel hub along X (mm). In-distribution range [12, 300]; values of 0 or outside the range are rejected as out-of-training.
Right knee bolster to X Pre_test right_knee_bolster_to_x_pre_test number 285 Pre-test distance from the right knee bolster to the X-reference point (mm). In-distribution range [162, 406]; values of 0 or outside the range are rejected as out-of-training.
Left knee bolster to X Pre_test left_knee_bolster_to_x_pre_test number 288 Pre-test distance from the left knee bolster to the X-reference point (mm). In-distribution range [206, 415]; values of 0 or outside the range are rejected as out-of-training.
Door Opening Pre_test door_opening_pre_test number 837 Pre-test door opening clearance (mm). In-distribution range [610, 1217]; values of 0 or outside the range are rejected as out-of-training.
