French experience shows that it is possible for buses or tramways (light rails or tramways on tyres) to compete with private cars under certain conditions: good organization of stations and commuting nodes, devoted and protected lanes for public transport, traffic signal priorities at crossroads in favour of buses or tramways, information at stop on the delay before arrival of next vehicles, integration of tariffs when using several lines during the same journey and multimodal fare collection system.

法国的经验告诉我们，在一定的条件下，公交车和电车完全可以和私家小汽车竞争。即公交车和电车具有良好的站点组织和通勤方式，专用的公交车道，十字路口的公交或电车的优先信号，车辆到站之前提供有关延误的信息，同一出行中多次换乘时车费在不同交通票务方式之间的结合等竞争优势。

This time you're not the driver of the trolley car,you are an onlooker.you are standing on a bridge,overlooking a trolley car track,and down the track come the trolley car, at the end of the track are five wokers.the brakes don't work.the trolley car is about to crash into the five and kill them.and now you are not the driver,you really fell helpless.until you notice standing next to you,leaning over the bridge is a very fat man.and you could give him a sholve,he will fall over the bridge onto the track.right in the way of the trolley car.he would die but he would spare the five.now how many would push the fat man over the bridge .raise your hands.

现在，你不是电车司机，你是个旁观者，你站在桥上，俯瞰电车的电轨，沿着轨道尽头有5个工人。电车手刹照样不灵了。电车快要撞向这5人。你不是司机，你真的感觉很无助。突然，你看见站在你旁边，桥边还有一个非常胖的人，你可以推他一把，他会掉到轨道上，刚好能停住车。他会死去，但能救活其他5个人。有多少人会推那个胖子？
