40、交通拥堵做贡献。同时对软件的开发知识、软件的功能特点和研究内容进行了介绍。 在高科技和信息技术快速发展的时代,信息技术正逐渐应用到城市基础设施经营管理。90年代以来,国际流行的智能公交系统,利用先进的电子技术的城市公共交通系统的综合管理。在21世纪,特别是在,智能手机和安卓系统的发展,基于安卓智能公交旅游系统软件也出现,本文介绍了基于智能公交旅行安卓系统软件设计。虽然智能公交出行系统软件很实用，市场也很需要，但城市规模的不断扩建，使公共交通系统日益庞杂。发展智能公共交通系统是解决城市交通问题的有效途径。 公交车辆定位技术是自动收集公交车辆运行情况的有效方法,是建立智能公交系统的基础和前提。现今

41、，公交车仍是广大市民出行的主要交通工具，因而公交信息服务显得越来越重要。而随着城市信息化建设的推进以及信息智能终端（智能手机）的普及，充分利用现代通信技术和计算机网络技术使百姓的出行更为方便和快捷必将成为一种发展趋势。就城市公交而言完全可以利用现代化的通信手段打造更为人性化的服务手段，解决人们出行所面临的公交信息方面的问题。通过实施智能公交信息导航系统可以解决城市公交运行信息与用户之间互动的问题，让用户及时获知公交车的运行动态，提高用户对公交出行的认可度，为解决城市交通拥堵，提倡“绿色出行”做出更多的贡献。因此，在对现有公交系统不足进行分析的基础上,为提高公交行业的服务水平和管理水平,提出了实

42、施智能公共交通系统、优先发展公共交通战略的技术保障公交信息智能化管理系统,即建立一个低成本、高效益、科学管理、安全生产的现代化智能公交信息服务系统,并给出了系统的实施框架及关键理论和技术的解决方案.这款是基于android的智能公交出行系统的软件，需要将所学的知识综合运用起来，还需要学习一些新的知识java,android，myeclipse，数据库等方面的知识，下面作简要的介绍。1. android开发平台是由谷歌与开放手机联盟 合作开发的一个开放、自由的移动终端平台，它由操作系统、中间软件、应用软件三部分组成。该平台备有完善的程序开发环境，包括模拟器、除错工具、程序执行所耗用存储器、性能评

43、介等功能。平台提供了两个基于位置服务的地图api开发包。通过两个地图api开发包内与位置服务相关的类的使用，配合设备本身的具备的定位定向等相关模块，可以很好地实现对用户移动空间信息服务应用程序开发。android以其集成的独特的地图服务模块，以及对硬件性能的低要求，对3g等无线网络的迅捷访问功能，为普通用户开发移动公交查询系统带来了很大的便利，它的出现，为解决用户移动空间信息需求提供了高效的开发平台。2. java是由sun 公司于1995年5月推出的java面向对象程序设计语言 （以下简称java语言）和java平台的总称。由james gosling 和同事们共同研发，并在1995年正式推

44、出。用java实现的hotjava浏览器 （支持java applet）显示了java的魅力：跨平台 、动态的web、internet 计算。从此，java被广泛接受并推动了web的迅速发展，常用的浏览器均支持java applet。另一方面，java技术也不断更新。(2010年oracle 公司收购了sun )java由四方面组成：java编程语 、java类文件格式、java虚拟机和java应用程序接口 (java api)。java平台由java虚拟机 （java virtual machine，简称jvm ）和java 应用编程。接口（application programming i

45、nterface，简称api ）构成。java 应用编程接口为java应用提供了一个独立于操作系的标准接口，可分为基本部分和扩展部分。在硬件 或操作系统平台上安装一个java平台之后，java应用程序就可运行。3. sql(structured query language)是一种数据库查询和程序设计语言，用于存取数据以及查询、更新和管理的关系数据库系统。sql是高级的非过程化编程语言，允许用户在高层数据结构上工作。他不要求用户指定对数据的存放方法，也不需要用户了解具体的数据存放方式，所以具有完全不同底层结构的不同数据库系统可以使用相同的sql语言作为数据输入与管理的接口。它以记录集合作为操作对象，所有sql语句接受集合作为输入，返回集合作为输出，这种集合特性允许一条sql语句的输出作为另一条sql语句的输入，所以sql语句可以嵌套，这使他具有极大的灵活性和强大的功能，在多数情况下，在其他语言中需要一大段程序实现的功能只需要一个sql语句就可以达到目的，这也意味着用sql语言可以写出非常复杂的语句。4.myec
