摘要：移动型采集技术是运用移动的车辆来检测道路上固定标识物，从而确定交通参数的方法。这项技术可用于先进的交通管理系统采集交通流数据。综合考虑了交通流数据的质量、成本等因素，对安装在车辆上的移动型检测器的样本量进行了研究，提出了移动型检测器最小样本量确定的一般原则和方法，并对最小样本量进行了优化设计。利用微观仿真模拟软件对城市道路移动型样本量方案进行模拟，确定了满足ATMS系统需要的移动型检测器采用的最小样本量。

Abstract: This article introduces a data collecting technique that uses floating-vehicles to detect fixed marks along a street, so as to determine traffic parameters. The technique can be used in Advanced Transport Management Systems (ATMS) to collect traffic flow data. This paper discusses the sample size, a critical issue in using the floating-vehicle detection technique while considering the data quality, cost and other factors, and presents general principles and methods for determining and optimally designing the smallest sample size. Micro-simulation software was used to simulate different sample-sizes, and thus to determine the smallest sample size of floating-vehicle detectors that meets the need of ATMS.

Key words: urban road; floating-vehicle detector; sample-size; simulation analysis
