    • Continuously extracting traffic load and speed on roads within the coverage area of a cellular network using only data that arrives to the cellular switch implanted in the following stages: (a) a learning phase, which can include vehicle(s) with a location device (i.e., a GPS system) traveling across the covered routes and collecting cellular data and location data in parallel, analyzing the accumulated data and processing the date to create a reference database; and (b) an operational stage in which communications on the cellular network are monitored continuously, and matched against the reference database in to locate their route and speed. The data analysis and data base structure are provided in a manner that enables in the operational stage fast and reliable initial identification of the vehicle's route, based only on the cell ID of handovers; follow-up forward and backwards of the vehicle's route; and real-time incident detection.

    • A system and method that continuously extracts traffic load and speed on roads within the coverage area of a cellular network. The data is extracted directly from communications in a cellular network without using any external sensors. The method enables correlating a car to a road it travels on and determining its speed by using only the partial data that arrives to the cellular switch. The method consists of the following stages: A learn phase, which can include a vehicle(s) with a location device (say GPS system) travels across the covered routes within a designated area and collects the cellular data (cell handover sequences and signal strength reports) and location data in parallel. The accumulated data is then analyzed and processed to create the reference database. An operational stage in which communications on the cellular network control channel are monitored continuously, and matched against the reference database in order to locate their route and speed. The route and speed data is used in order to create a traffic status map within the designated area and alarm in real time on traffic incidents. The data analysis and data base structure are done in a manner that will enable the following: Very fast, high reliability initial identification of the vehicle's route in the operational stage, based on handovers' cell ID only. Very fast, high reliability follow up forward and backwards of the vehicle's route in the operational stage. Real time, high reliability Incident detection.
    • 一种在蜂窝网络覆盖范围内连续提取业务量和速度的系统和方法。 直接从蜂窝网络中的通信提取数据,而不使用任何外部传感器。 该方法使得汽车与其行进的道路相关联,并且仅使用到达蜂窝交换机的部分数据来确定其速度。 该方法包括以下阶段:学习阶段,其可以包括具有位置设备(例如GPS系统)的车辆在指定区域内穿过被覆盖的路线,并且收集蜂窝数据(小区切换序列和信号强度 报告)和位置数据并行。 然后对累积的数据进行分析和处理,以创建参考数据库。 在蜂窝网络控制信道上的通信被连续监视并与参考数据库匹配以便定位其路由和速度的操作阶段。 使用路线和速度数据,以便在指定区域内创建交通状况图,并实时报警交通事故。 数据分析和数据库结构的完成方式将能够实现以下目标:基于仅切换小区ID,在运行阶段对车辆路由进行非常快速,高可靠性的初始识别。 在运营阶段,车辆路线的前进和后退非常快,可靠性高。 实时,高可靠性事件检测。
