Graph-Based ANPR Dataset of Tourist Routes and Visits in Smart Villages of Alpujarra

This dataset comprises license plate data collected using Automatic Number Plate Recognition (ANPR) devices as vehicles entered or exited the smart village area of Alpujarra, which includes three towns: Pampaneira, Capileira, and Bubión. The sensor network consists of four Hikvision IP cameras that leverage deep learning-based ANPR technology to ensure complete coverage of vehicular movements. Each camera is equipped with vehicle detection sensors, a 2MP resolution, varifocal lenses (2.8–12 mm), and infrared LEDs with a 50-meter range. In this dataset, the nodes correspond to the four cameras: two at the entrance and exit of Pampaneira (PAM1 and PAM2), one at the entrance of Bubión (BUB), and one at the entrance of Capileira (CAP). Tourist routes are represented as graphs where each route forms a unique graph structure. Data was recorded from February 2022 to December 2024.

The dataset covers 467,773 distinct vehicles and includes the following variables:

num_plate_id: An anonymized license plate number.route: The sequence of nodes (camera identifiers) representing each tourist visit; possible values are PAM1, PAM2, CAP, and BUB.times: The travel time in seconds between consecutive nodes.entry_date: The timestamp when the vehicle was first detected.exit_date: The timestamp when the vehicle was last detected.directions: A sequence indicating the travel direction at each camera (1 for entering, 0 for exiting).num_visits: A label representing the total number of visits by that tourist from February 2022 to December 2024.
