ITS作为城市交通发展的一项重要投资,对其产生的效益进行评价正日益受到普遍重视.使用回归模型评价ITS提升城市交通畅通性的贡献,并以广州市为例进行实证分析,得到2011和2012年ITS对交通畅通性的贡献分别为9.23%和23.74%.研究结果显示,ITS对提升交通畅通性具有一定的贡献价值,但由于其应用的滞后性,价值只有在后期不断积累中才能逐渐表现出来.
As an important investment in the development of urban transport, ITS is gaining more and more attention in the evaluation of the benefits it generates.Using regression models to evaluate the contribution of ITS to enhancing the accessibility of urban transportation, and taking Guangzhou as an example, The contribution of ITS to traffic flowability was 9.23% and 23.74% respectively in 2012. The results show that ITS contributes to the improvement of traffic flowability, but due to the lag of its application, the value can only gradually increase in the later period Show it.
