A driving analysis server may be configured to receive vehicle operation data from vehicle sensors, and may use the data to identify a potentially high-risk or unsafe driving event by the vehicle. The driving analysis server also may receive corresponding image data, video, or object proximity data from the vehicle or one or more other data sources, and may use the image, video, or proximity data to analyze the potentially high-risk or unsafe driving event. A driver score for the vehicle or driver may be calculated or adjusted based on the analysis of the data and the determination of one or more causes of the driving event. |

1. A driving analysis system comprising a first vehicle on-board data recording system and a driving analysis server:
wherein the first vehicle on-board data recording system comprises:
one or more vehicle operation sensors configured to record vehicle operation data at a first vehicle;one or more cameras or object proximity sensors configured to record image, video, or proximity data at the first vehicle; andone or more telematics devices configured to transmit the vehicle operation data and the image, video, or proximity data from the first vehicle to the driving analysis server, wherein the driving analysis server comprises a processor and a memory unit storing computer-executable instructions, which when executed by the processor, cause the driving analysis server to:
receive a driver score associated with a driver of the first vehicle;receive first vehicle operation data from the first vehicle on-board data recording system;identify a first driving event of the first vehicle based on the first vehicle operation data;receive at least one of image data, video data, and proximity data from the first vehicle on-board data recording system corresponding to the first driving event;identify at least a first cause of the first driving event and a second cause of the first driving event, wherein identifying the at least a first cause and a second cause comprises:
attempting to identify at least two external causes of the first driving event by analyzing at least one of the image data, video data, or object proximity data received from the first vehicle on-board data recording system corresponding to the first driving event;if at least two external causes can be identified:
identifying a first external cause and a second external cause;based on the analysis of the at least one of image data, video data, or object proximity data corresponding to the first driving event, determining a percentage of cause associated with each of the first external cause and the second external cause;evaluating the determined percentage of cause of the first external cause and the second external cause to identify one of the first external cause and the second external cause as a primary cause, the primary cause being the cause having a percentage greater than a predetermined event cause threshold;determining whether the primary cause was unsafe or high-risk driving;responsive to determining that the primary cause was unsafe or high-risk driving, adjusting the driver score;responsive to determining that the primary cause was not unsafe or high-risk driving, maintaining the driver score based on the first driving event; andif at least two external causes cannot be identified, determining that high-risk or unsafe driving by the driver of the first vehicle was the cause of the first driving event and adjusting the driver score based on the at least two external causes not being identified; andoutput at least the first cause of the first driving event. |
