Prepare representative inputs
Collect or simulate camera frames or telemetry and label the target signals (counts, classes, events), and partition by sensor, location and time to avoid leakage.
Monitor traffic at the edge. Inspect latency and model size.
Edge traffic monitoring detects and classifies road events (vehicle counts, vehicle type, congestion) using on-device models and sensor or camera inputs. Real deployments must balance detection accuracy with strict latency, memory and power budgets and handle occlusion, weather and camera-angle variation.

Edge traffic monitoring detects and classifies road events (vehicle counts, vehicle type, congestion) using on-device models and sensor or camera inputs. Real deployments must balance detection accuracy with strict latency, memory and power budgets and handle occlusion, weather and camera-angle variation.
A proposed application: a roadside unit that counts vehicles and flags congestion for a traffic-operations dashboard. In any operational setting a human operator should review flagged incidents before automated traffic control actions are taken.
Collect or simulate camera frames or telemetry and label the target signals (counts, classes, events), and partition by sensor, location and time to avoid leakage.
Fit a small model on the training set and save a deterministic pipeline so you can compare later changes and optimisations.
Measure per-sample latency, memory footprint and CPU usage on target hardware in addition to detection metrics such as mean average precision or F1 for the chosen task.
Define runtime validation, drift detection and a rollback strategy; create dashboards for false positives and edge-case review.
The supplied starter creates a synthetic tabular classification dataset with sklearn.make_classification, trains a scikit-learn DecisionTreeClassifier, then measures repeated single-sample prediction latency in Python and prints tree depth and node count. It does not use traffic camera frames, sensor telemetry, TensorFlow Lite, MQTT or any edge runtime.
X, y = make_classification(n_samples=1000, n_features=12, n_informative=8, random_state=42)
model = DecisionTreeClassifier(max_depth=6, random_state=42)
model.fit(X, y)
sample = X[:1]
start = time.perf_counter()
for _ in range(1000):
model.predict(sample)The starter uses synthetic tabular data and a desktop scikit-learn decision tree, so it does not validate traffic-specific inputs (camera frames or sensor telemetry), edge runtimes (TFLite/ONNX), or real-world latency on target hardware. The synthetic labels and small in-memory latency loop are insufficient to claim suitability for an edge traffic-monitoring device.
A proposed extension: replace the synthetic data with labelled camera frames or sensor logs, convert a lightweight detector to TensorFlow Lite or ONNX, measure latency on the target device, and add an MQTT endpoint for streaming counts to a dashboard.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
