HOW TO USE THE MATRIX

The matrix has been organized by the type of physical design strategies and problems they are most effective in combating. This does not mean that strategies will not overlap or be the same when looking at various modes of transportation. Most strategies will work towards creating a safer environment for all types of transportation and not be specific to just one mode. Additionally, the design strategies will be most effective when partnered with another strategy or even policy.

Along the top axis, you can find the conditions for which a crash happened. Each of the conditions will try to best align with the design strategies that are countermeasures to reduce the chances of crashes happening again.

Additional information involving the design strategies, including cost and how to best administer them within a community are addressed. The matrix focuses on where the countermeasures are most applicable as well, if it best used in a rural or urban setting, or a highway strategy.

Definitions

Temporary Approach: countermeasures that can be “tested” to determine success before finalizing the change (with various exceptions)

Systematic Approach: countermeasures are implemented at all locations (across the community)

Systemic Approach: countermeasures are implemented at locations with the greatest risk (specific locations within the community)

Site Specific Approach: countermeasures are implemented based on crash data that supports continual crashes at one specific site that needs to be addressed (one location within the community)

Cost Explanation

Cost is determined based on one installation (i.e. one round-a-bout, one shareduse path, one crosswalk, etc.) and is further explained in each countermeasure section.

Low-cost ($0-$99,999)

Medium cost ($100,000 - $499,999)

High cost ($500,000 and up)

Range of costs (depending on level of implementation)
