The State of Minnesota has under way its Toward Zero Deaths (TZD) initiative, the goal of which is to eliminate
fatal traffic crashes. This is a daunting task, and with limited financial resources, optimal strategies that provide the
greatest benefit for a given cost have to be utilized if the goal of TZD is to be met.
This report reviews both infrastructure and emerging in-vehicle solutions as a means to determine the optimal
deployment strategy of countermeasures designed to improve highway safety. Infrastructure-based solutions are
examined on two levels: 1) an analysis of a cross-section of strategies implemented throughout Minnesota, which
2) produced a before:after analysis that quantified the effectiveness of a variety of strategies utilized in Minnesota.
In addition to the standard civil engineering countermeasures studied under the before:after analysis, emerging
infrastructure and in-vehicle technology-based solutions were modeled in terms of effectiveness and potential
deployment schedules. These cost and effectiveness models facilitated a comparison to the results of the
before:after analysis, and from the comparison, optimal strategies for improving safety with limited funds and the
TZD goal are presented.
