摘要： 交通事故记录的位置信息是事故分析研究的重要基础。中国大量的道路交通事故数据以记录 发生地的地址或者明显标志物的方式描述事故位置信息，无法批量处理并直接用于数据分析，而人 工标定过程烦琐、效率较低、成本较高。通过算法对道路交通事故记录的位置信息进行切分、匹 配，并按照描述标定到指定位置，达到自动转换的效果。该方法可实现交通事故记录位置标定的自 动化，提高数据处理的效率，降低成本，为道路交通事故信息的空间分布研究提供数据支撑，也为 海量处理数据提供可能。

Abstract： The location information of traffic accident records is an important basis for accidents analysis and research. A large number of traffic accident data describe their location information by recording the location of accident or obvious signs, which cannot be processed in batches and directly used in data analysis. However, the manual calibration process is cumbersome, inefficient and costly. Through the algorithm, the location information of road traffic accidents records is segmented and matched, and calibrated to the designated location according to the description, so as to achieve automatic conversion. The method can achieve the automatic calibration of traffic accident record location, improve data processing efficiency, reduce the cost, provide data support for the spatial distribution of road traffic accident information, and also provide powerful support for processing massive data.
