Railroad Crossing Study
Crashes at railway grade crossings kill over 500 people
per year and injure 1,754 and 45 percent of injury crashes
and 42 percent of fatal crashes occur at rail grade crossing
protected only with cross bucks. The low power requirements
of LED signals and piezo sensors make it practical to power
these signals with a solar array in any part of the nation.
Vehicle speeds were measured by the Polk County Traffic
Engineering Division using two counter hoses. The eyes
were activated by a microwave sensor that detected approaching
vehicles at a distance of 150 to 180 feet. The introduction
of the animated eyes sign at the
passive rail crossing reduced the percentage of motorists
not stopping or significantly slowing at the site by about
half. These data are consistent with other data showing
that the efficacy of the eyes display
at crosswalks, garage exits and midblock crossing sites.
