CIEACT is an online web tool capable of analyzing and extracting valuable information from crash narratives using text mining techniques. It provides an opportunity to develop multiple models concurrently and analyze the results. CIEACT provides the following major functionalities:<\/p>\n\n\n\n

    \n
  1. Real-time Crash Classification Using Developed (default) Model.<\/li>\n\n\n\n
  2. Real-time Model Development & Crash Classification.<\/li>\n\n\n\n
  3. Crash Analysis.<\/li>\n\n\n\n
  4. Result Visualization.<\/li>\n\n\n\n
  5. Result Download.<\/li>\n<\/ol>\n<\/div>\n\n\n\n

    It gives users the option of training their own models or using a default model that has already been trained. The current version of CIEACT uses a NoisyOR based hybrid (unigram + bigram) classifier for both the default model and the training of a new model. Currently, the default model is applicable for wok zone crash classification. CIEACT was tested both offline and online using different types of electronic devices. During the testing process, the tool showed satisfactory performance with all designed functionalities working properly. A case study was also conducted to evaluate the functionality of a custom model that allows users to train their model in real time. <\/p>\n\n\n\n

    CIEACT can assist in extracting valuable information from narratives, recovering missed crashes, and reviewing the results in both tabular
    and spatial contexts. The tool can help to analyze crashes and implement new policies to enhance structural data quality and determine effective safety measures.<\/p>\n\n\n\n
