【摘要】 现阶段,伴随着城市人口日益膨胀,城市公共交通的压力越来越大。尤其是在发展中国家,这一瓶颈问题日益突出。提高城市公共交通智能管理水平,合理调度公交车辆,是近期解决城市公交紧张矛盾的最为有效的措施。城市公共交通是随客流、道路条件、气候等不断变化的随机服务系统。客流数据包括乘客上下车人数、上下车时间、相应站点等是整个公交企业管理业务的基础,快速、准确地采集车辆的客流信息为科学合理地安排调度车辆、优化公交线路等智能管理提供了最基本的依据,还可以全面如实地反映公交车辆的实际载客人数,方便与钱箱收入之间的核对。本文介绍了目前比较普遍的客流计数方法和人体运动学的相关知识。在此基础上,研究了公交环境下人体上下台阶时足-地接触力变化的规律性,并将此规律应用到了客流计数中,提出了一种新的客流技术方法——基于人体运动学的客流计数法。并通过实验证明了新方法在实际中的可行性及有效性。以客流计数为核心研发了一套结合GPS、GPRS、蓝牙及压力传感技术为一体的智能信息采集系统。更多还原

【Abstract】 Nowadays,the pressure of public transportation is becoming bigger and bigger with the increase of urban population,especially in developing countries . The most effective measure to solve this plight is to improve the management level of urban transportation and reasonably dispatch buses. The urban transportation is a stochastic service system which changes with passenger flow,path condition,weather and so on. The passenger flow data including the number of passengers,the information about station and so on is the basis of public transportation management. Correct and real-time data of passenger flow can provide the most important information for reasonably dispatching buses and optimizing lines of public transportation,and it can also show the actual number of passengers to be convenient for checking back the cash in the cashbox . This paper introduces some general count methods of bus passenger flow and the theory about kinematics of human body. And it analyzes the characteristic of thenar pressure caused by stepping on bus pedal. In this paper,we propose a new counting method of bus passenger flow based on kinematics of human body and proved the feasibility and effectivity of the new method through experimental results. Researched and developed a set take the passenger flow counting as the core to unify GPS, GPRS,the blue tooth and the pressure sensing technology is a body intelligent system of gathering information.更多还原
