| 摘 要： | 针对当前GIS -T中对于交通事件表达的不足,首先利用交通波理论计算交通事件对路网影响范围的时空变化情况;其次基于线性参考和标准动态分段思想,在标准动态分段中增加时间维属性,通过程序扩展在现有GIS平台上实现时空动态分段方法,并用该方法实现交通事件影响临近路段范围的时空变化可视化表达.结果表明,利用时空动态分段方法可以... |

| Abstract: | Two steps are introduced to solve the deficiency of traffic incident representation in current GIS-T.First,the spatio-temporal change of traffic incident's influencing scope was computed by using traffic wave theory.Second,the spatio-temporal dynamic segmentation was represented by adding temporal attributes based on classical dynamic segmentation and linear reference,which was realized in GIS software by additional program.Then,the spatio-temporal change of affected adjacent road links was represented acco... |
