The embodiment of the application provides a traffic route planning method and system based on a prediction algorithm. The method comprises the following steps: recording the driving condition of a road in each time period, and obtaining the capacity limit of the road in each time period through a statistical method; carrying out pre-navigation on each user, and carrying out statistics on information of all user vehicles that are going to enter the road; predicting the traffic flow of the road in a specified time period according to a real-time traffic flow of the specified road to obtain an estimated traffic flow; predicting the number of users who are going to enter the road in a specified time period to obtain an estimated entering flow; adding the estimated traffic flow and the estimated entering flow to obtain a traffic flow prediction result; and under the condition that the traffic flow prediction result is greater than or equal to the capacity limit, screening out a screened user set needing to switch the navigation route according to a screening rule, and re-planning a navigation route avoiding the road for the users in the set. According to the application, the efficiencyof traffic route planning is improved through a prediction algorithm.
本申请实施例提供一种基于预测算法的交通路线规划方法和系统。该方法包括:记录道路每个时段的行车情况,通过统计方法得出道路在各个时段的容量极限;对每个用户首先进行预导航,统计全部拟进入道路的用户车辆信息;根据指定道路的实时车流量,预测出在指定时段中道路的车流量,得到预估车流量;预测在指定时段中拟进入道路的用户数量,得到预估进入流量;将预估车流量与预估进入流量相加,得到车流量预测结果;如果车流量预测结果大于或等于容量极限时,按照筛选规则筛选出需要切换导航线路的筛选用户集合,为集合中的用户重新规划避开道路的导航路线。本申请通过预测算法提高了交通路线规划的效率。
