高德地图城市大脑公开亮相，这一招百度还能接的住吗？
6月19日，在世界交通运输大会期间，高德地图联手阿里云在北京发布城市大脑·智慧交通战略，城市大脑·智慧交通公共服务版也首次亮相。期间，高德集团总裁刘振飞指出，高德此举旨在为政府部门做好服务，为用户出行节省时间，并在未来的科技之城中发挥重要作用。
众所周知，作为导航产品，高德、百度相争由来已久，相对于上个月百度与易车的合作，这次高德推出产品显然更加受人关注，可以说，这一局是高德赢了。
城市大脑为什么叫大脑?
此次对于高德地图的城市大脑产品，发布会上介绍了很多功能，但是在笔者看来，它实际上就是以地图导航获取的人、车、路相关数据为依托，并将这些数据进行有机整合，并通过一定的算法程序，然后来形成一个类似控制中心的职能。简单来说就是它先通过位置、生活、交通、社会等不同种类的海量数据得出不同的计算结果，再从中寻找最优解，为政府部门疏导交通和为用户规避拥堵进行指导。在作者看来，本质上这个产品没有脱离地图导航，只不过结果更加精确有效，不过也正因为精确，才使得百度难以企及。
数据是高德获胜的关键
熟悉的人恐怕都知道，高德作为国内市场七家图商之一，测绘能力和数据采集能力非常突出，加之2002年以来的深度积累，以及并入阿里之后的数据整合，7亿用户和150多座城市的交通信息让高德的基础数据库建设非常完善，导航的精准度也更高。而百度由于没有相关测绘资质，大部分数据都要依靠第三方地图商，那么在数据基础上就差了很多，精准度也就大受影响。
高德推出的这款产品，不但数据清晰可见，更有阿里云的鼎力支持，大数据的分析、计算、模拟都细致入微，最终的结果，也会体现的非常得当。例如：通过信号灯配时优化，让机动车通过路口的平均延误下降了6%、停车比例降低了3%，为用户提供10种出行方式等等，可以说完全是以精准见长的，一下戳中了百度地图的软肋。
此外，高德还提出了未来所谓“无人之境”的构想，但笔者认为，首先要能够接近才能有实现的可能，目前连无人驾驶汽车都没有批量生产，将来的发展变化还是很难说的，所以这个构想稍微有些不切实际。
