联网高速公路路径射频识别系统理论误差分析

射频技术是解决联网高速公路路径识别的一种可行技术.目前,国内已有个别省份采用该技术解决路径识别问题,但未进行国内大范围的推广.从射频设备的准确率、标识站点的设置方式、标识站与收费站的位置关系、收费站点间交通流分布等几个方面,分析整个识别系统中可能产生的理论误差,并引入综合误差度的概念对系统误差做统一标定.

Analysis of Theoretical Error on RFID System Used in Network Highway Route Selection

RFID technology is feasible to solve the route identification problem of the network highway. Now, this method has been used in some provinces of China, yet not in a large scale. In this paper, the theoretical error is analysized in the whole system from the following aspects like the accuracy of the RFID equipment, setting mode of identification station, positional relationship of identification station and toll station, distribution of traffic flow between toll stations, and the concept of synthesized error degree is introduced to describe the theoretical error.
