The invention provides a ramp flow analysis method, which comprises the following steps of: returning ETC door frame data and toll station exit lane data in real time, and creating an ETC door frame data table and a toll station exit lane data table according to the data of each complete natural month; creating an interchange ramp basic table, and storing basic information of each ramp of the interchange; generating an expressway exit detail table, and recording the passing path of each vehicle in the expressway; and finally generating an interchange ramp flow table. According to the method, the communication condition of the highway on-ramp is obtained by obtaining the interchange ramp basic table and the highway exit detail table, and the interchange ramp flow table is finally analyzed, so that the specific flow condition of the ramp can be obtained for reference of a driver, and a worker can timely adjust the flow of the ramp to avoid the congestion of the ramp.
本发明提供一种匝道流量分析方法,包括如下步骤:ETC门架数据、收费站出口车道数据实时回传,并根据每个完整自然月的数据创建ETC门架数据表、收费站出口车道数据表;创建互通立交匝道基础表,存放互通立交各条匝道的基础信息;生成高速通行出口明细表,记录每辆车在高速公路中的通行路径;最终生成互通立交匝道流量表。本发明通过获取互通立交匝道基础表和高速通行出口明细表,来获取高速上匝道的通信情况,并最终分析出互通立交匝道流量表,即可以得到匝道的具体流量情况,供司机参考,以及工作人员针对匝道流量进行及时调整,避免匝道拥堵。
