Cam随着城市交通复杂性增加和智能交通的飞速发展,单一指标的评价和诊断已不能满足我国交通运行的多样化。高德首创城市交通病诊断的综合性评价“交通健康指数”来全面刻画城市交通运行状况,该指数从时间、空间、效率的九项交通运行指标的综合评价,实现城市全方位立体化智慧运行诊断。该指数算法沿用国际通用的信息熵法客观确定评价指标权重(该方法在政府权威部门、社会经济、学术领域的各类报告中得到广泛普遍应用);同时,采用 TOPSIS正负理想解的计算进行排名,最终评分结果代表各城市九宫格指标与理想值之间的接近程度。“交通健康指数”越髙说眀离理想值越近,城市运行相对越健康;指数越低则说明多项指标距离理想值越远,相对越不健康。九项指标信息熵权重分配■权重确定方法—熵值法排名得分方法—TOPS|s1)各项指标运用最大最小值归一化处理,并考1)对于反向指标采用取倒数进行同向处理,然后进行数据规范化效率一骨干时间一路网虑指标的正反向进行调整2道路运行速高延时运行度偏差率,时间占比2)计算第项指标下第个样本值占该指标的比重刻率一高峰平为11.6%114%/时间-通勤2)利用欧式距离计算与最优最劣目标的距离,并乘以权重压力指数pp9.8%;{z;-x)2,D:(21-2)2效率一路网高时间一日拥3〕计算第j项指标的熵值行程延时捐数,10.7%堵经济损失e=-k∑p;lm(P;),=1,…,m3)计算各评价对象与最优方案的贴近程度空间一高峰12.6%缓行路段里空间一路网D:+D程比,98%高峰拥堵路4)计算信息熵冗余度空间一常发段里程比值越接近1,表示评价对象越优秀。在城市健康指薮中,所得结果即代表着该城市健康拥堵路段里10.3%d1=1程比5)计算各项指标权重水平与最优目标的接近百分比。15.2%d∑d最终计算各指标权重如左图所示。2018年度中国“交通健康城市”分布热力图高德地amap.

You canprogram mouse buttons to work in non-standard ways, as you mightwant to if you are left-handed. For simplicity, the left-hand hutton(under your forefinger if you are right-handed) is called the leftbutton, and the one on far right is the right mouse button. You willprobably find the terms intuitive once you use these buttons a fewtimesPoint and click; Right clickTo choose an item with the mouse, first move it on your desk until thearrow cursor is on that item; you are now pointing" at the item. Next,ress and release the left bu tton thlled"clicking " Point-andclick is the most common action you will make with your mouseally, click" refers to a lefise button clickYou can sometimes use your right mouse button to access or entercommands. In the 3d Modeler for instance, a right mouse buttonclick causes a short menu of commands to appear at the moustcursor. Generally, right click "refers to a right mouse button clickDouble-ClickOccasionally you may want to sclect all of thc text in a box,orperform a special lask(such as indicating the end of drawing a linewhile you are using Maxwell 3D. You can do this efficiently byquickly clicking twice with your left mouse button -a doubleDragging objects; Click and HoldWhen you are drawing in the 3D Modeler, you can often use yourmouse to enter objects and move around the screen. Frequently, youwill click the mouse button and hold it down until the next part of thecommand is reached (the object is oved, the next point is enteredand so forth).
