摘要：
A system and method are provided for determining malfunctioning traffic signals and lights. A traffic signal pattern is identified. Probe reports are received from a device. A path is generated including the road intersection for the device using location data in the two or more probe reports. The path is compared to a traffic signal. An abnormal crossing is determined from the comparison. A malfunction of the traffic signal is determined based on the abnormal crossing.
