讨论了高速公路线形安全性评价系统的设计目标、功能,从系统的软件体系架构、功能需求、工作流程以及数据流程等几个方面进行了系统的总体设计,并使用Java语言及Eclipse开发工具完成了系统开发。该系统实现了线形指标的规范符合性检查、基于公路线形的运行车速预测、进行线形的连续性评价及安全性评价,可以为公路线形设计提供评价、修正和优化的依据。
The design objectives and functions of the highway safety assessment system are discussed. The overall design of the system is carried out in terms of the system architecture, function requirements, work flow and data flow. The system is implemented using the Java language and Eclipse development tools System development. The system realizes the compliance inspection of linear indexes, predicts the running speed of highway based on line shape, evaluates and evaluates the linear continuity and safety evaluation, and can provide the basis for evaluation, correction and optimization of highway linear design.
