MnDOT relies on estimates of annual average daily traffic volumes to plan and maintain safe, effective transportation network infrastructure for all travelers. Estimating traffic volumes for nonmotorized road users such as bicyclists and pedestrians has been challenging because monitors are limited compared to vehicle traffic counters. Data from mobile devices, routinely collected through a variety of platforms, offers a potential source of traveler routes. Using monitored nonmotorized traveler data to validate mobile datasets, researchers produced a data visualization tool to estimate bicyclist and pedestrian counts within the Twin Cities area.

New Project: Mobile-Device Data, Non-Motorized Traffic Monitoring, and Estimation of Annual Average Daily Bicyclist and Pedestrian Flows
Understanding pedestrian and bicyclist flows is vital to distributing a limited construction budget to new infrastructure for improved safety on specific roads. Unfortunately, statewide data collection for active transportation flows is challenging.
MnDOT and local agencies historically have lacked estimates of bicycle and pedestrian traffic on Trunk Highways and County State Aid Highways.
Since about 2016, MnDOT has begun monitoring bicycle and pedestrian flow at more than 25 locations across the state, but, given the small number of counters and the variability of flows in response to variations in weather across Minnesota, these monitoring data are insufficient for estimation of Annual Average Daily Bicyclists and Annual Average Daily Pedestrians.
One option for obtaining travel data without expensive infrastructure is relying on mobile data collection.
