Federal Highway Administration (FWHA) requires that all new construction or modification schemes of interchanges must be modeled and analyzed prior to actual implementation. This means interchanges, adjacent interstate freeway system as well as related arterials, must be jointly modeled to determine the potential impacts on the entire interstate freeway system. To this end, traffic volume on the freeway as well as turning movement counts for arterial intersections are needed in order to generate actual arterial/freeway demands, calibrate traffic models and verify the model outputs.
In practice, freeway traffic volume data are collected using automatic data collecting/monitoring system such as loop detectors deployed on the freeway mainline and ramps; while intersection turning movement counts, for which cost-effective and accurate automatic data collection equipment has yet to be deployed, is usually manually collected by on-site personnel. The manually-collected turning movement data are susceptible to one typical type of error, i.e., the total input flow doesn’t match total outflow for individual arterial links. This means the flow conservation principle of traffic flow theory is violated and hence is considered erroneous.

ArtBaT( Arterial Data Balancing Tool) is a Windows© software package designed and developed at the University of Minnesota for balancing arterial intersection turning movements data
The discrepancies among intersection turning movements data can be effectively reconciled using ArtBaT internal optimization engine. Specifically, ArtBaT 1.0 can handle up to 17 types of intersections, with JAMAR data collector data, or user-prepared ASCII data file as input.
Reconciled arterial intersection data can be used in conjunction with balanced freeway data in Interstate Access Request study as requested by FHWA.
