The invention discloses a method and device for calculating indexes of a traffic state in real time. The method comprises the following steps: acquiring real-time vehicle passing data of each vehicle;according to the real-time vehicle passing data, updating the travel chain set of each vehicle; and judging whether there are a plurality of newly added vehicle passing data in the travel chain wherethe real-time vehicle passing data in the travel chain set of each vehicle is located: if yes, performing vehicle passing data error correction on the travel chain where the real-time vehicle passingdata is located, and then determining a real-time traffic state index according to the corrected vehicle passing data of the travel chain in the travel chain set of each vehicle. The indexes of the traffic states of all intersections in a city are calculated in real time, and the instantaneity and accuracy of the indexes of the traffic states are improved.

    本发明公开了一种实时计算交通状态的指标的方法及装置,包括:获取各车辆的实时过车数据,然后根据实时过车数据,更新各车辆的出行链集合,判断各车辆的出行链集合中实时过车数据所在的出行链中新增过车数据是否为多个,若是,则对实时过车数据所在的出行链进行过车数据纠错,然后根据纠错后的各车辆的出行链集合中出行链的过车数据,确定出实时交通状态指标。以实现实时的计算出城市中全部路口的交通状态的指标,提高交通状态的指标的实时性,准确性。
