EVENT DATA BASED TRAFFIC DETECTOR VALIDATION TESTS

摘要: This paper presents eight detector validation tests using individual vehicle data, commonly referred to as event collected from loop detectors. Five of these can be applied single detectors, while all them dual The are used contrast the performance between different sensor models and most presented 24 hr blocks data. In practice, they also identify permanent transient hardware problems in other components detection system, e.g., cross talk loops or a short lead wires. For operational implementation, could modified so that hourly after fixed number vehicles pass. Some even "clean up" erroneous measurements
