摘要:

GPRS/ZigBee 交通诱导信息发布装置通过GPRS无线网络获取交通信息管理 中心发布的交通诱导信息,然后通过ZigBee 无线网络发送到车载信息接收装置,车载信 息接收装置再通过文语转换技术将交通诱导信息用语音的方式播报出来.为了发挥 GPRS/ZigBee 交通诱导信息发布装置的最大效用,本文提出了该信息发布装置的一种选 址方案.首先,本文建立了总量-广度数学模型,然后又建立Logit-SUE模型,利用MSA算 法求解SUE模型,得到每个路段流量和公共路段系数,最后计算出信息发布装置在每个 路段的总效应,确定选址方案.本文利用包含20 个节点,62 条路段的路网进行了选址仿真 实验,实验结果验证了该方案的可行性.

Abstract:

The paper presents a new traffic guidance device, which is GPRS/ZigBee traffic guidance information releasing device. The traffic guidance information is sent to GPRS/ZigBee traffic guidance information releasing device from the traffic information management center by GPRS wireless network. Then the GPRS/ZigBee traffic guidance information releasing device sends the traffic guidance information to the information receiving device by the ZigBee wireless network. The information receiving device then broadcast the traffic guidance information with the text to speech (TTS) technology. In order to make the GPRS/ZigBee traffic guidance information releasing device has the maximum effect, a layout scheme of the device is provided. Firstly, the total-width model is presented. Secondly, the Logit-SUE model is established. In order to acquire the link flow and public roads coefficient of each road, the Logit-SUE model is solved with MSAAlgorithm. At last, we figure out the total effect and determine the location decision. A simulation experiment is conducted with the road network which included 20 nodes and 62 roads. The results of the experiment confirm the application of the model.

Key words: intelligent transportation, GPRS/ZigBee traffic guidance information releasing device, totalwidth model, Logit-SUE model, optimal location
