• Abstract:
  Vehicles that enter freeway exit ramps going the wrong way present one of the most serious traffic hazards on ; Arizona’s urban freeways. Moler cites a study that finds on average 350 people are killed annually in the United ; States as a result of wrong-way crashes (Moler 2002). This typically occurs due to one or more of these reasons: ; (1) the driver is impaired; (2) the driver gets distracted or is confused; or (3) the signage and markings are ; difficult to follow. The primary focus of this research was to determine the viability of existing detector systems to ; identify entry of wrong-way vehicles onto the highway system using five different technologies: microwave ; sensors, Doppler radar, video imaging, thermal sensors, and magnetic sensors. The devices were installed on ; freeway exit ramps. Each device was tested in both a controlled environment and in the field under normal traffic ; operating conditions. During the controlled testing, staged events were conducted to determine whether the ; devices would accurately detect wrong-way vehicles. The study results of this proof of concept effort verify that ; wrong-way vehicles can be detected using easily deployable equipment that is currently available on the market. ; While each system tested over the trial period had missed or false calls, none of the systems were installed ; under the vendors’ ideal conditions.
