隨著都市發展的越來越繁榮,人口越來越密集,交通也成了日益嚴重的問題。若是每個人都開著車流竄在城市的街頭,那一定會完全癱瘓了交通。於是政府建設了各項的大眾運輸交通設施提供給所有的市民搭乘,其便利的交通網路幾乎遍及了城市甚至於是國家的每一個角落。而有時其錯綜複雜的運輸網路與各自為政的發車時刻表有時卻反而令民眾非常的困擾,這時我們就需要一套能夠幫助我們規劃路線的導航設備。然而現今一般市售的GPS導航設備,清一色都是為了行車導航使用,雖然相關產品也已經達到非常成熟的狀態,但卻幾乎沒有任何一款設備是為了大眾運輸提供導航的,就算有也單單只有規劃行程而欠缺導航的功能。有鑒於此本篇論文就利用時下發展蓬勃,包含GPS定位與三維座標系統的Android手機來開發一個專用於大眾運輸導航的提醒系統來輔助一般常常搭乘大眾運輸的民眾。
With the growing population of city development, traffic has become an increasingly serious problem. The traffic of city will be paralyzed if most of the people are driving on streets. Therefore, the government builds many public transit facilities for all citizens. The convenient transportation network covers all over the country, but the complicated network and the fragmented schedules always make people feel disturbed. Therefore, we must need a device that can help us to plan route navigation. However, most of the GPS navigation devices salt in markets are all for car navigation. The car navigation techniques are quite mature but there are almost no device has public transit navigational function. In view of this, by using the popular Android smartphones which includes GPS positioning and three-dimensional coordinate system. This thesis proposed a system with navigation and reminder functions to the people who often take public transit.
