Description
本发明属于互联网领域，尤其是涉及一种末班车提醒的方法以及提醒系统。 The invention belongs to the field of the Internet, and in particular relates to a method for reminding the last bus and a reminding system.
城市公共交通对城市政治经济、文化教育、科学技术等方面的发展影响极大，也是城市建设的一个重要方面。城市特别是大中城市，交通压力大，堵车严重，效率低下，如果大力发展城市公交，它可以缓解城市交通压力，而且城市中都设有公交车专用道，地铁以及轻轨更不用说了，不存在堵车的情况，大大的方便了市民出行。同时，城市公交还能起到环保节能的作用。因为，城市公交越方便快捷越发达，人们出行在成本的决定下，选择公共交通的市民就越多，势必使用私家车辆的数量就会减少，所以一定会减少汽车的尾气排放和大量能源的使用，特别是石油的使用量的减少，因此，保护了环境节约了能源。Urban public transportation has a great impact on the development of urban politics, economy, culture, education, science and technology, and is also an important aspect of urban construction. Cities, especially large and medium-sized cities, have heavy traffic pressures, serious traffic jams, and low efficiency. If urban buses are developed vigorously, it can alleviate the pressure of urban traffic, and there are bus lanes in the city, not to mention subways and light rails. The situation of traffic jams greatly facilitates the travel of the citizens. At the same time, urban public transport can also play a role in environmental protection and energy conservation. Because the more convenient and faster the city bus is, the more people choose to travel by public, the more people choose public transportation, the less the number of private vehicles will be used, so it will definitely reduce the exhaust emissions of vehicles and the use of a lot of energy. In particular, the use of oil is reduced, thus protecting the environment from energy.
但是，城市公交没有做到24小时运营，所以存在首发时间和末班时间的情况。我们经常会遇到这种情况，由于工作繁忙或是与同事朋友相聚等情况，常常会忘记时间赶不上末班车回家，只能叫出租车，费用增加的同时可能还不安全，尤其是年轻女性的人身安全。还有一种情况就是，用户外出在熟悉的地方还好说，能够知道回家的乘公交的路线和公交车的末班时间。但是如果用户身在不熟悉的地方，回家的乘车路线和末班车时间就不一定了解，因此，可能会错过末班车的时间。细心的用户可能会提前规划线路和了解公交车发车时间，但是这样的查询，操作起来又比较麻烦，不是很方便。However, urban buses do not operate 24 hours a day, so there are cases of starting time and last time. We often encounter this situation. Due to busy work or gathering with colleagues and friends, we often forget that time can't catch up with the last bus to go home. We can only call a taxi. The cost may increase and it may not be safe, especially for young women. Personal safety. There is also a case where the user goes out in a familiar place and can say that he can know the route of the bus going home and the last time of the bus. However, if the user is in an unfamiliar place, the home route and the last bus time are not necessarily known, so the last bus may be missed. Careful users may plan the route in advance and understand the bus departure time, but such a query is more troublesome to operate, not very convenient.
综上，针对于当前用户不知道末班车时间错过乘车，并且查询末班车时间和规划回家路线的操作比较复杂，用户体验不佳的情况，需要提供一种能够主动提醒用户末班车时间和规划乘车线路的方法。In summary, for the current user does not know the last bus time missed the ride, and the operation of querying the last bus time and planning the home route is more complicated, and the user experience is not good, it is necessary to provide a kind of initiative to remind the user of the last bus time and plan the ride. The method of the line.
