Highway Safety Evaluation System Based on Design Consistency and Accident Prediction Model

In order to find out the road sections that may have traffic safety hazards in the design stage of expressway, this study carried out the design of expressway safety evaluation system for the design stage. Based on the analysis of system requirements, requirements objectives and workflow, the safety evaluation system of highway design stage is designed, including database module, specification compliance review module, design consistency evaluation module, accident prediction module, map operation module and user operation module. In this study, a safety evaluation model based on design consistency and accident prediction factors is presented, utilizing the integration of MapInfo and SQL Server database. The model library is constructed, and subsequently, standard compliance review and design consistency evaluation are conducted. The system can realize visualization and docking with road design software. The adjustment of design scheme and data statistics and analysis can be realized by using the callback technology of MapInfo. The design, evaluation and optimization of expressway can be coordinated synchronously, and the safety of expressway in design and operation stage can be evaluated.
