+    # Nigeria Transport & Logistics – Traffic Signal Timing
+
+    Intersection phases, cycle times, offsets, and optimization flags.
+
+    - **[category]** Infrastructure & Environment
+    - **[rows]** ~100,000
+    - **[formats]** CSV + Parquet (snappy)
+    - **[geography]** Nigeria (major cities, corridors, ports, airports)
+
+    ## Schema
+
+    | column | dtype |
+|---|---|
+| intersection_id | object |
+| phase | object |
+| start_time | object |
+| green_sec | int64 |
+| yellow_sec | int64 |
+| red_sec | int64 |
+| cycle_time_sec | int64 |
+| offset_sec | int64 |
+| optimized | bool |
+| corridor_id | object |
+
+    ## Usage
+
+    ```python
+    import pandas as pd
+    df = pd.read_parquet('data/nigerian_transport_and_logistics_traffic_signal_timing/nigerian_transport_and_logistics_traffic_signal_timing.parquet')
+    df.head()
+    ```
+
+    ```python
+    from datasets import load_dataset
+    ds = load_dataset('electricsheepafrica/nigerian_transport_and_logistics_traffic_signal_timing')
+    ds
+    ```
+
+    ## Notes
+
+    - Nigeria-specific parameters (fleets, roads, traffic, fuel prices)
+    - Time-of-day traffic effects and seasonal impacts where applicable
+    - Physical plausibility checks embedded during generation
