Appendices Updated Appendix K Emerging and Alternative Traffic Data Collection TechnologiesNew Appendix L Use Cases of New and Multiple Data Sources New Appendix M Example Packages for Modelling

Commentaries Amended Commentaries to support high-level modelling guidelines

1313

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
