AADT from Non-Traditional Methods Pooled Fund Reports

FHWA led pooled fund TPF-5(384) TPF - Study Detail (pooledfund.org) researched using passive data to determine traffic volumes and the limitations of such uses. Please see the FHWA PF website or the 5 reports for further study details. The term of "passively collected data" means data are not collected through traditional roadway point based sensor detection. The five initial research results are presented here for your use in helping to guide further work in this area.
