移动的观测器方法自上个世纪中期以来一直被交通工程师用于估计交通速度、流量和密度。虽然简单直观，但该方法存在两个主要问题。首先，车辆必须在其参数所关注的交通的方向上以及在相反方向上穿过给定的路段，基本上在环路中行驶。第二，为了得到准确的结果，必须进行多次运行并将结果汇总。我们的变体利用当今车辆的通信能力来缓解这两个问题，从而实现更快，更准确的交通地图和交通路线应用。广泛的仿真结果已经证实，我们的变体的移动的观察员方法是可比的精度与固定的观察员方法，即使在较低的流速。
The mobile observer method has been used by traffic engineers since the middle of the last century to estimate traffic velocity, flow and density. Although simple and intuitive, the method suffers from two major issues. First, the vehicle must traverse a given road segment both in the direction of the traffic whose parameters are of interest and also in the opposite direction, essentially driving in a loop. Second, to get accurate results, several runs must be taken and the results aggregated. Our variant utilizes the communication capabilities in present-day vehicles to mitigate both these issues, thus enabling faster and more accurate traffic maps and traffic routing applications. Extensive simulation results have confirmed that our variant of the mobile observer method is comparable in accuracy with the stationary observer method even at lower flow rates.
