For most safety properties and some liveness properties, model checking can be reduced to reachability analysis. 实时系统的绝大多数安全性和部分活性可以通过可达性分析算法来验证。
Neither regression analysis nor cross-classification analysis thoroughly demonstrates the relevant relationship between trip generation and accessibility to traffic zones. 在出行生成模型中，无论是回归分析还是发生率法或类别生成法都很少能体现出行生成与地区区位和可达性之间的相关关系。
