摘要： A system and a method for determining the average time taken by vehicles to travel along road sections are described, in which a plurality of peripheral units (12, 14) distributed along a road network is used to detect the transit of vehicles by interrogating an on-board apparatus (B) of said vehicles, in particular an on-board apparatus designed for interfacing with land-based apparatus of an automatic toll collection system.
The peripheral units (12, 14) are connected to a central processing unit (20) which collects the data relating to the identification codes of the on-board apparatus (B) of the vehicles and the associated moments of transit past at least one pair of peripheral units (12, 14) and determines the average travel time of the section on the basis of the travel times of a plurality of vehicles detected passing by said peripheral units (12, 14).摘要翻译： 描述了一种用于确定车辆沿着路段行驶所花费的平均时间的系统和方法，其中沿道路网分布的多个周边单元（12,14）被用于通过询问一个接通来检测车辆的过境 车载设备（B），特别是设计用于与自动收费系统的陆基设备接口的车载设备。 外围单元（12,14）连接到中央处理单元（20），该中央处理单元（20）收集与车辆的车载设备（B）的识别代码相关的数据，以及相关联的过境时刻至少一对 的外围单元（12,14），并且基于通过所述外围单元（12,14）检测到的多个车辆的行驶时间来确定该部分的平均行驶时间。

摘要： A system (1) for detecting the speed of vehicles, particularly for sections of roads and highways, comprising a plurality of peripheral units, each of which comprises a unit (2) for detecting the class and speed of a vehicle, and at least one video camera (3) for acquiring the image of the license plate of the vehicle, the peripheral units being connected to a central processing unit (5), the peripheral units being further provided with a peripheral processing unit (11) that is adapted to identify the license plate acquired by the video camera, the central processing unit (5) determining the average speed of the vehicle on the basis of two distinct detections performed by two successive peripheral units.
