Model Based Fault Detection of Freeway Traffic Sensors

  title={Model Based Fault Detection of Freeway Traffic Sensors},
  author={Gunes Dervisoglu and Roberto Horowitz},
This paper presents a model based fault detection and exclusion scheme that implements a decision logic to automatically identify faulty or mislocated freeway traffic sensors in the presence of unknown on-ramp and off-ramp flows. The algorithm is deployed within the framework of a suite of software tools, named TOPl, which models traffic flow via a macroscopic model, calibrates the model based on available data and runs simulations to evaluate various operational strategies such as ramp… CONTINUE READING
