Data Collection Methods BluFax: vehicle identification using bluetooth MAC addresses – provides corridor traffic patterns (origin-destination data) and vehicle travel-times in SR-91 corridor study area Wavetronix: vehicle detection radar units – provides 100% vehicle classification counts (auto and truck) in SR-91 corridor study area PeMS: vehicle counts and speeds using Caltrans in-pavement vehicle detection induction loops (450+ locations throughout Riverside, San Bernardino, Orange and Los Angeles Counties)

SR-91 Corridor Travel Patterns BluFax and Wavetronix data was collected between November 1 st and November 10 th 2010 Data was aggregated to provide average weekday AM and PM peak period travel patterns consistent with modeling time periods Combining the BluFax origin-destination traffic data (in percent) with the Wavetronix classification count data provides complete corridor AM and PM peak period travel patterns
