| 摘 要： | 通过分析城市交通畅通性的影响因素及其与ITS(智能交通系统)的关系,挖掘ITS对城市交通畅通性的贡献率指标.搜集实证研究对象数据,采用灰色预测模型预测贡献率指标的数值,将ITS示范工程实施前后的数值进行对比,计算得到ITS示范工程对城市交通畅通性的贡献率.由贡献率结果判断ITS示范工程对城市交通畅通性的作用及ITS示范工程的实施效果如何,为未来ITS的发展提供相应的参考建议.

| Abstract: | By analyzing the influence factors of city traffics smooth general characteristic and its relationship with ITS (Intelligent Transportation System),the paper excavates metrics that ITS contributes to smooth general characteristic of urban traffic.Collecting data of empirical research object,using grey prediction model to predict value of contribution index,comparing before and after the demonstration project of ITS,contribution is calculated which is demonstration project of ITS for urban traffic's smooth general characteristic.Through the contribution rate to judge function that demonstration project of ITS is to smooth general characteristic of city traffic and effect of ITS demonstration project,it provides corresponding advice for future development of ITS. |
