Transportation practitioners are constantly bombarded with ads for the latest and greatest, cutting-edge roadway safety technologies, only to find that it’s difficult to discern which products actually best address crash problems. There are few resources that aggregate the answers to critical performance questions that are accessible and easy to use. You need to know:

  • AdobeStock_227508092_1000x517How well does the technology really work?
  • Who else has deployed it?
  • Is it a proven crash countermeasure?

Yet, these questions are often lost in well-made marketing materials and single site pilots with lots of fanfare.

Navjoy found that although traditional crash countermeasure (rumble strips, cable rail, etc.) toolboxes are widely available, a technology-focused toolbox was not. As part of the Colorado Department of Transportation’s (CDOT’s) push to update the 2020-2023 Colorado Strategic Transportation Safety Plan (STSP), Navjoy took on this problem by preparing a technology-driven crash countermeasures toolbox, which you can download using the form to the right.

The toolbox is aimed at equipping practitioners to quickly match proven, reliable Intelligent Transportation System (ITS) technology to the most prevalent crash patterns experienced in a specific jurisdiction. The need for this is driven by the ongoing push toward Vision Zero – eliminating roadway fatalities.

What's included

For each technology with substantiated deployments listed, the toolbox provides the following:

  • Name and brief description of the product
  • Countermeasure type (in-vehicle, on-road, site-specific, etc.)
  • Relative level of deployment (global, United States, etc.)
  • Primary crash types mitigated
  • Qualitative assessment of capital deployment costs (low, medium, high)
  • Qualitative assessment of crash reduction potential (low, medium, high)
  • Links to evaluation, deployment, and guideline references

For each of the technologies that are emerging or conceptual, the toolbox also contains descriptions for those that might be available for installation as part of pilot or research studies in the future.
