New and alternative data sources
• Bluetooth
• Mobile phone tracking
• GPS-based probes
• Public transport ticketing
• Drones
• On-board Mass (OBM)
See Section 2.6
1414
Benefits/potentials of alternative data sources• Great geographic and temporal coverage
• Easier acquisition of long-term continuous traffic data (high resolution and frequent intervals)
• Increased accuracy and detail
• Cost per unit of useful information
• Currency of data collection and processing
• Data collected for one purpose can often be re-used
• Use traditional methods more selectively
See Section 2.6
1515
Limitations
• Limited sample size on low-volume roads
• May still rely on roadside equipment
• Limited applicability to measure total traffic volumes
• Historic data may or may not be available
• Potential sample bias
• Concerns regarding locational privacy
1616
Supporting techniques
• Additional requirements for data collection, storage and processing
• Advanced data analytics
• Statistical techniques
• Road network visualisation
• Information privacy and security
