US-75 and K-9 Traffic Study

The Kansas Department of Transportation (KDOT) wanted to address safety concerns, like poor sight distance and near-miss crashes, at the intersection of US-75 and K-9 in Jackson County, Kansas. To assess the current state, they asked our team to conduct a traffic study.

We were responsible for collecting traffic volume and speed data at the intersection. The volumes were then projected to a future 20-year time frame. KDOT also provided 5-year crash history at the intersection for review and analysis.

The data collected was used to develop a list of low, medium, and high-cost options to improve safety and operations at the intersection. At least two preliminary layouts were prepared for each. Those were given to KDOT for review, along with a planning level construction cost estimate and benefit/cost analysis, in a report. Now, they have the information needed to determine their next steps.
