The invention provides a road condition information broadcasting method and system, a computer and a storage medium, and the method comprises the following steps: determining the initial position information and destination information of a vehicle to obtain the driving range of the vehicle, and obtaining and storing the road condition information related to the driving range in real time to form an information base; acquiring a plurality of integer ambiguity of the vehicle and baseline parameters corresponding to the integer ambiguity; determining the current positioning information of the vehicle through the integer ambiguity and the baseline parameter; delimiting a driving area of the vehicle according to the initial position information, the current positioning information and the destination information; and matching the road condition information in the information base with the driving area to extract and broadcast the road condition information corresponding to the driving area. By determining the driving range, the road condition information can be filtered for the first time, and a basis is provided for screening the road condition information in the information base through the driving area, so that the road condition information is filtered for the second time, and the relevancy between the road condition information and travelers is improved.

    本发明提供一种路况信息播报方法、系统、计算机及存储介质,方法包括以下步骤:确定车辆的初始位置信息及目的地信息,以获取车辆的行驶范围,实时获取并存储与行驶范围相关的路况信息,以形成信息库;获取车辆的若干个整周模糊度及与整周模糊度对应的基线参量;通过整周模糊度及基线参量确定车辆的当前定位信息;通过初始位置信息、当前定位信息及目的地信息划定车辆的行驶区域;将信息库内的路况信息与行驶区域进行匹配,以提取并播报与行驶区域对应的路况信息。通过确定行驶范围,可对路况信息进行一次过滤,通过行驶区域,为信息库内的路况信息筛选提供了依据,以对路况信息进行二次过滤,提高了路况信息与出行者的相关度。
