Clear Roads: Training Module Development for Evaluation of Storm Severity Index and Winter Severity Index Variables

Leave a comment

Reprinted from Clear Roads News November 27, 2024

Clear Roads project 18-03, Evaluation of SSI and WSI Variables, produced a step-by-step guide and flowchart tool to help agencies identify or develop severity index methods to fit their needs and available data sources.

As estimating the impact of weather on roadway maintenance resources is becoming an increasingly important issue for agencies across the country, a recently completed Clear Roads project, 21-04, Training Module Development for Evaluation of Storm Severity Index and Winter Severity Index Variables, produced additional training modules geared toward three key audiences: division directors, snow and ice managers, and supervisors.

Incorporating audiovisual materials, discussion topics, and interactive exercises, the training modules will help practitioners design and develop indexes to suit their agency’s particular needs.

Download the final report and two-page brief: CR 21-04 – Training Module Development for Evaluation of Storm Severity Index and Winter Severity Index Variables, July 2024.

Improving Traffic Signal Visibility

Leave a comment

Inconspicuous traffic signals are often cited as contributing to collisions at intersections. If that is true, making traffic signals more conspicuous should lead to fewer crashes.  A study published at the TRB conference in 2005 suggested that yellow retroreflective backplates were most effective, reducing accidents by 15% at intersections, and the FHWA later adopted this as a Proven Safety Countermeasure.

Identifying Risk Factors for Deer-Vehicle Collisions

1 Comment

Deer-vehicle collisions are a significant safety hazard on Minnesota roads. While MnDOT strives to employ safety measures on roads at high risk for these collisions, identifying these areas can be challenging. Numerous variables impact where deer are more likely to be present near roads, and many collisions go unreported. A new tool estimates the risk levels—based on road type, geographical features, deer population and other characteristics—for each road segment in the state. In addition, a new method of estimating reporting rates will help MnDOT understand the extent of deer-vehicle collisions in a specific area.

Crowdsourcing meets transportation planning with bike and pedestrian data counts

Leave a comment

Increasing active transportation is an ongoing effort for transportation planners. Biking and walking can help decrease auto dependence, air pollution, and climate change and improve public health. Plus, it can help transportation agencies meet their strategic goals. The challenge? Making good decisions requires good data, and data for walking and biking trips can be hard to find.

Applying for Grants: Use Data to Tell Your Community’s Story to USDOT

Leave a comment

Research done here at Minnesota and elsewhere has done much to define the problems of local communities with missing or declining infrastructure. USDOT offers federal assistance to build and improve that infrastructure, but the grants have to be won.
