在城市交通控制系统的通信中，可以采用数传电台、GSM短消息、光纤接入等方式。数传电台的优势是除了每年的频点费以外，平时运行无需额外费用；缺点是受地形、气候的影响较大，造成系统的可靠性、实时性较差，无法主动上报。GSM短消息方式可以实现主动上报；缺点是按条收费，运行费用高，而且在节假日短消息中心服务器繁忙时延时相当长。光纤通信稳定可靠，但是施工成本投入大、扩展性差、设备维护方面不方便。而GPRS通信则避免了以上问题。
通用分组无线业务GPRS是在现有GSM系统上发展出来的一种新无线数据传数业务，目的是给移动用户提供高速无线IP或X.25服务。GPRS理论带宽可达171.2Kbit/s，实际应用带宽大约在40～100Kbit/s，在此信道上提供TCP/IP连接，可以用于INTERNET连接、数据传输等应用。GPRS采用分组交换技术，每个用户可同时占用多个无线信道，同一无线信道又可以由多个用户共享，资源被有效的利用。GPRS允许用户在端到端分组转移模式下发送和接收数据，而不需要利用电路交换模式的网络资源。GPRS永远在线，按流量计费，从而提供了一种高效、低成本的无线分组数据业务。特别适用于间断的、突发性的和频繁的、点多分散、中小流量的数据传输，也适用于偶尔的大数据量传输。
二、系统概述
该城市交通控制系统能将实现区域或整个城市交通监控系统的统一控制、协调和管理，采用符合工业标准的通信和系统集成技术，具有稳定性好、可靠性高的优点。GPRS城市智能交通控制系统的网络架构如下图所示，系统分为三个部分，分别是交通管理中心主站、GPRS数据传输终端、现场设备包括车辆检测器、信号控制机、电子警察等。主站主要完成人机交互工作；GPRS数据传输终端完成信息的上送与下发；现场设备主要完成现场交通信息的采集和信号灯的控制等。
