transbigdata-taxi

What problem does it solve?

Cleans noisy taxi GPS records and extracts passenger trip origins and destinations to enable rapid OD analysis and trajectory separation for urban transport studies.

Core Features & Use Cases

• Status cleaning: Remove instantaneous and spurious passenger status changes to improve trip detection quality.
• OD extraction and aggregation: Derive pickup/dropoff times and locations and aggregate results into grids or administrative areas for heatmaps and flow analysis.
• Trajectory separation: Split datasets into passenger-carrying and idle (cruising) trajectories for operational analysis and visualization.
• Use case: Clean a city's taxi GPS feed, extract OD pairs, aggregate to 500m grids, and produce geospatial outputs for mapping and further modeling.

Quick Start

Analyze my taxi_gps.csv to clean status anomalies, extract OD pairs, separate passenger and idle trajectories, and save the OD results as taxi_od.csv.
