Crashes are random events and consequently, can occur at any location along the roadway. On
roadways with higher traffic volumes, the more frequent occurrence of crashes allows for the
direct identification of high crash locations using historical data. However, on local roads, crash
occurrence, particularly fatal and serious injury crashes, is less frequent. This makes it difficult
to identify trends and treat hazardous sites based on historical data. Geometric, traffic and other
features may lend themselves toward crashes potentially happening in spot locations. Therefore,
an approach to identifying these types of risk factors on low volume roads is necessary.
The proposed research will identify risk factors and features that contribute to crashes along low
volume roads and the cost effectiveness of countermeasures to address them. Research objectives
Identify risk factors and features that contribute to crash occurrence and which can be corrected
by selected low cost countermeasures, with a specific focus on low and moderate volume roads
with sporadic crash occurrence.
Develop a risk index of different factors and features that practitioners should look for and that
can be addressed using selected low cost countermeasures along low and moderate volume
Establish the cost effectiveness/thresholds for the low cost countermeasures that are selected for
use in addressing risk factors on low to moderate volume roads.
Conduct limited case studies to demonstrate the use of the identified risk factors and application
of the cost effectiveness thresholds that are developed.
