Measuring Intra-Urban Mobility Efficiency and Extracting Traffic Corridors Based on GPS Data

Key Points

• The aim is to quantify the efficiency of urban mobility and identify traffic corridors using GPS data in Tokyo.
• Used GPS data from Tokyo to analyze urban mobility efficiency.
• Identified regional discrepancies in mobility efficiency based on demand.
• Extracted traffic corridors primarily along railway lines.
• Regions identified with high demand yet low efficiency included urban eastern areas and railway voids in Tama.
• Found low mobility efficiency in directions orthogonal to railway lines and along major roads.
• Revealed that the strength of extracted traffic corridors varies by railway line.
