摘　　要：公交车舒适度可以反应公交车服务水平,有助于建立高品质公交线路。通过对比分析公交车运营中的各种环境参数与所载乘客的主观感受,建立了公交车舒适度(OBC)评价模型,并设计了一套基于嵌入式的舒适度监控系统。系统采用S3C2440微处理器芯片,集成温湿度传感器、加速度传感器、声卡模块,同时设计了基于Qt的人机交互界面。该系统能实时监测公交车运营状态,在舒适度较低的时候向驾驶员发出警告,实验表明,安装该系统的公交车,舒适性有了较大幅度的提升。In order to improve the level of bus service, a field study was undertaken to develop a combined bus comfort model. By comparing the subjective views of bus passengers to objective physical parameters, a combined bus comfort model was established. An effective system integrated the comfort model,measuring instrument and the driver monitor could greatly improve the bus service quality. This system is combined of S3C2440,humidity and temperature sensor,digital accelerometer and audio CODEC.
