The invention relates to an intersection traffic prediction method and an intersection traffic moving and static prediction method on a path thereof, and belongs to the field of application of traffic information. Comprising the following steps of giving or automatically obtaining predicted date and time, obtaining information of an intersection database in an intelligent control system, judging whether a predicted road has a week rule according to an analysis chart of intersection passing data obtained by a retrieval analysis module, and performing retrieval to obtain a week rule. According to historical data records retrieved in the intersection database in the fourth step, the left-turn passing probability, the straight-going passing probability, the average straight-going passing time length, the average left-turn waiting time length, the average left-turn passing time length and the like are calculated, and the method can be used for dynamic and static passing prediction of the intersection on the navigation path. The method has very high real-time performance and feasibility, and has important assistance and basic support effects on improving the intelligent level of navigation and automatic driving in the future.
本发明涉及一种交叉口通行预测及其路径上交叉口通行动、静态预测方法,属于交通信息的应用领域。包括如下步骤,给定或自动获取预测日期时间,获取智能控制系统中交叉口数据库的信息,根据检索分析模块得到的交叉口通行数据的分析图表判断预测的道路是否有星期规律,进行检索,根据步骤四在交叉口数据库检索出的历史数据记录,计算出左转的通行概率、直行的通行概率、直行通行的平均时长、左转等待的平均时长、左转通行的平均时长等,该方法可用于导航路径上交叉口动态、静态通行预测。本发明有着很高的实时性、可行性,对提升导航的智能化水平,对未来的自动驾驶,都有着重要助力和基础支撑的作用。
