根据深圳市出租车GPS数据所提供的信息,针对交通出行数据的空间分布特征,选取了4月18号这天的全天数据出租车载客后的行驶数据, 利用mtalab对数据的处理,筛选出出租车的起始点及拥堵的时段的行驶数据并通过kmeans聚类分析设定拥堵的标准,得到对于出租车在路段上的车速在小于2.15公里/小时的时候可以认为非常拥堵,拥堵的时段 5:00-7:00,12:00-14:00,19:00-21:00,非常拥堵的时间段为5:00-7:00,19:00-21:00。
English Description:
According to the information provided by GPS data of taxis in Shenzhen, and in view of the spatial distribution characteristics of traffic data, this paper selects the whole day data of April 18, the driving data of taxis after carrying passengers, Using Mtalab to process the data, this paper selects the starting point of taxi and the driving data of congestion period, and sets the congestion standard through kmeans clustering analysis. It is concluded that when the speed of taxi on the road is less than 2.15 km / h, it can be considered as very congested, and the congestion period is 5:00-7:00, 12:00-14:00, 19: 00-21:00, 5:00-7:00, 19:00-21:00 in very congested time.
