SBIR Phase I: Feasibility of Using Anonymous Cell Phone Tracking for Generating Traffic Information

这个小型企业创新研究(SBIR)第一阶段项目是对使用匿名跟踪手机来生成公路网上的交通信息的可行性进行调查。由于拥堵造成的延误，无论是从损失的时间还是从恶化的角度来看，都是代价高昂的。由于缺乏关于当前状况的信息，管理拥堵是困难的。虽然大多数信息是通过安装在道路上的昂贵的探测器系统收集的，但通过跟踪被称为探测器的样本车辆的移动来确定交通状况是可能的。许多车辆都有移动电话，由于FCC最近的一项规定，要求所有电信运营商能够在125米内定位移动电话，因此有机会建立一个系统，其中可以使用大量移动电话的移动来确定公路网中每条道路的情况。该项目将决定运营商安装的定位系统是否可以用于生成交通信息。研究结果将有助于开发一个区域范围的交通信息系统，用于发布出行信息和研究路网上的交通模式。该项目成果的商业应用分为三个领域：交通管理、车队运营和信息发布。交通信息对于路网用户来说是很有价值的。交通管理包括全国各地的许多公共机构，它们的任务是帮助管理道路。车队运营商由大型和小型送货车辆组成。信息传播包括移动电话、个人数字助理、车载显示系统、网站和无线电。这三个市场都受到交通拥堵的严重影响，特别是意想不到的拥堵。每个市场都很大，而且可以通过基于手机跟踪的交通信息系统进行商业寻址。

This Small Business Innovation Research (SBIR) Phase I project is an investigation of the feasibility of using anonymous tracking of cellular phones to generate traffic information on a road network. Delays due to congestion are expensive both in terms of lost time and in aggravation. Management of congestion is difficult due to lack of information on current conditions. While most information is gathered via expensive detector systems installed in the roadways, it is possible to determine traffic conditions by following the movements of sample vehicles, called probes. Many vehicles contain a cellular phone, and, due to a recent FCC mandate, which requires that all telecommunication carriers be capable of locating a cellular phone to within 125 meters, an opportunity exists to build a system where the movements of a large number of cell phones can be used to determine conditions on every road in a road network. This project will determine whether thelocation systems installed by the carriers can be used to generate traffic information. The results will enable the development of an area-wide traffic information system which can be used for the dissemination of travel information and for the study of traffic patterns on road networks.Commercial application of the results of this project fall into 3 areas: traffic management, fleet operations, and information dissemination. Traffic information is valuable to the users of the road network. Traffic management includes the many public agencies around the country tasked to aid in the management of the roads. Fleet operators consist of large and small delivery vehicles. Information dissemination includes cellular phones, personal digital assistants, in-vehicle display systems, websites and radio. All three markets are significantly affected by traffic congestion, particularly unexpected congestion. Each market is large and commercially addressable by a traffic information system based on cell phone tracking.
