This research establishes the minimum detectable error (MDE) boundary for relative position between the observer and status vehicles (SV) using vehicle sensor and Global Positioning System (GPS) error profile from field tests and established minimum standards. The results demonstrated that the MDE increases in the lateral direction (side-to-side) with the increase in relative distance between the observer and SVs while remaining the same in the longitudinal direction (front-to-back). The implementation of Sensor-Based Misbehavior Detection (SBMD) with current specifications without GPS, sensors, and heading improvements can detect two-lane lateral offset malicious misbehavior and one vehicle length longitudinal offset malicious misbehavior with a probability above 99%. For one-lane lateral offset malicious misbehavior, there is a detection probability of approximately 30% at 70 meters distance and approximately 60% at 10 meters distance between observer and SV. Major improvements to sensors and heading error yield an improved detection for one-lane lateral offset malicious misbehavior with a probability approximately 60% for all distances while major improvements to GPS yield 100% detection of one-lane lateral offset malicious misbehavior. SBMD with current accuracy specifications without GPS, sensor, and heading improvements can detect GPS equipment failure where the GPS error profile is expanded to 3 times the current SAE J2945 specifications with a probability of approximately 42% at 70 meters distance and approximately 48% at 10 meters distance between observer and SV. This research found that major improvements to vehicle sensor and heading error reduces the MDE boundary lateral radius spread, thus decreasing the correlation between range and MDE boundary size.
