3A Hrycay_Incorporating Active Transportation Networks into Accident Prediction Models


Crash Modification Factors (CMFs) are used as a means to evaluate the expected number of
collisions after implementing a given countermeasure at a specific site. To date, there have
been numerous studies on CMFs in relation to motor vehicle accidents and roadway features.
As more municipalities incorporate active transportation networks into their infrastructure
planning, it is important to develop CMFs as a tool to help agencies evaluate the potential safety
improvements of various cycling infrastructure treatments while also considering the capital cost
to implement these treatments. Separated cycling facilities achieved the greatest reduction in
collision rates, though these types of installations are typically more expensive to implement.
Less-expensive on-road installation options such as on-road bike lanes or “sharrows” still result
in a significant reduction in collision rates.
