【摘要】：随着居民收入和生活水平的提高,现有的公共交通服务水平已然不能满足民众日益增长的出行需求,而公共汽车作为城市公共交通的重要组成部分,其服务水平对于改善民众出行质量,提高城市公共交通服务水平,提高居民幸福感有着极其重要的作用,同时,公交车舒适度的提高,有助于吸引乘客采用公交出行,优化城市交通结构。本文提出了一种公交车舒适度评价与监控系统,采用统计学的方法对公交车舒适度OBC (Overall Bus Comfort)的主要影响因素进行了分析,并结合主观评价与客观检测,定量的计算出乘坐舒适度,最后,通过对城市交通分担率进行建模,研究了常规公交舒适度对城市交通结构的影响,验证了该系统对于城市交通结构合理化的积极作用。本文主要做了以下几方面工作： (1)分析了我国现阶段城市的各种交通方式,总结了目前主流交通方式的利弊,确定了以舒适性为重点的常规公共交通发展思路。 (2)确定公交车舒适度量化方法,将主观评价(乘客问卷调查)与客观检测(热舒适度、噪声、振动、纵向加速度变化率)进行有效的结合,同时兼顾个体差异(年龄、性别、健康程度)对整体评价的影响,采用多元线性回归模型评价公交车舒适度。 (3)设计了一种公交车舒适度监控与评价系统,包含其软硬件设计及系统实用性论证。 A.硬件设计：主处理器S3C2440A、存储单元、3.5寸的LCD、温湿度传感器SHT11、音频接口UDA1341TS、加速度传感器ADXL345、电源模块的电路设计。 B.软件设计：Boot Loader的移植、配置、编译、Linux内核的移植、配置、编译、构建支持QT的根文件系统、人机交互界面程序实现。 (4)探究影响城市交通分担率的主要因素,采用非集计(LOGIT)模型对常规交通、家用车交通分担率进行建模,验证了常规公交舒适度对于城市交通结构合理化的积极作用。
[Abstract]:With the increase of residents ' income and living standard , the existing service level of public transport is not enough to meet the increasing demand of public transport , and the service level of bus is an important part of urban public transport . ( 1 ) The traffic modes of the present cities in China are analyzed , and the advantages and disadvantages of the current traffic modes are summarized , and the general public transport development thinking based on comfort is determined . ( 2 ) To determine the method of quantitative bus comfort quantification , combining subjective assessment ( passenger questionnaire ) with objective detection ( thermal comfort , noise , vibration , longitudinal acceleration change rate ) , and taking into account the influence of individual difference ( age , sex , health degree ) on the overall evaluation , and using multi - linear regression model to evaluate bus comfort . ( 3 ) Design a kind of bus comfort monitoring and evaluation system , including its hardware and software design and system practicability demonstration . A . Hardware design : main processor S3C2440A , storage unit , 3.5 - inch LCD , temperature and humidity sensor SHT11 , audio interface UDA1341TS , acceleration sensor , and circuit design of power module . B . Software design : Boot Loader migration , configuration , compilation , Linux kernel migration , configuration , compilation , build support QT root file system , man - machine interactive interface program implementation . ( 4 ) To explore the main factors that influence the city traffic allocation rate , adopt the non - lumped ( LOGIT ) model to model the traffic sharing rate of the regular traffic and domestic vehicles , and verify the positive effect of the normal public transport comfort on the rationalization of the urban traffic structure .
