Highway 169 Mobility Study

Twin Cities, Minnesota

Through interagency cooperation, the Minnesota Department of Transportation, the Metropolitan Council, and Scott County, MN are undertaking the Highway 169 Mobility Study. The sponsoring agencies selected SRF Consulting to lead the effort to evaluate the feasibility of adding MnPASS high occupancy/ toll express lanes and/or highway bus rapid transit (hBRT) along Highway 169 in the southwestern portion of the Twin Cities.

The scope of this interdisciplinary study includes assessment of existing traffic and transit conditions, development of managed lane and transit alternatives, and alternative evaluation and prioritization. The evaluation includes travel demand forecasting, market analysis, travel time reliability evaluation, traffic operations analysis, and benefit-cost. The study will ultimately recommend a feasible set of improvements along Highway 169 and an implementation plan for their phased deployment.

A key feature of the Highway 169 study was the market analysis conducted to assess existing passenger and freight movements in the region. This was performed using INRIX Trips and Waypoints data, showing the movements of 1.6 million trips within the study area. Along with more than 250 million waypoints providing routing information, SRF’s big data team leveraged knowledge of travel demand modeling tools and GIS spatial analysis to perform detailed analytics on these records. Products developed to inform the study included: select link travel patterns, route diversion analysis, cluster analysis of concentrated destinations, freeway ramp-to-ramp patterns, and station area market analysis. These results were critical to project stakeholders in assessing the location and utilization of potential highway and transit investments.
