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.
Through analyzing the influential factors of urban traffic flowability and its relationship with ITS (Intelligent Transportation System), this paper explores the contribution rate of ITS to the urban traffic flowability.We collect the data of empirical research object, predict the value of the contribution rate index by gray prediction model, Compare the values of ITS demonstration project before and after implementation, and calculate the contribution rate of ITS demonstration project to the urban traffic flow rate. Judging from the contribution rate results, the contribution of ITS demonstration project to urban traffic flow and the effect of ITS demonstration project are The future ITS development provides the corresponding reference suggestion.
