abstract="This project sought to determine the effectiveness of various low-cost countermeasures for reducing the number of fixed object and overturning crashes. A survey was conducted of the 50 state highway and transportation departments. Responses to the questionnaire show that all states are using chevron markers, and a majority are using delineators and standard warning signs. Respondents thought that these devices were most effective for reducing run-off-the-road crashes, although little documentation was supplied to support this contention. Most states have established procedures for selecting the most hazardous run-off-the-road sites, but few have formal guidelines for selecting the specific countermeasures for use at these sites. A critical analysis is needed to determine the actual effectiveness of several commonly used low-cost countermeasures.
