北京地铁涨价，大家要多花多少钱？

Beijing citizens will say goodbye to the city's low price transportation system next month with the municipal government announcing subway and bus fare hikes The new fares, which formally take hold on December 28, put bus fares starting at two yuan (32 cents) and subway fares at three yuan. The new fares would double the current prices on average, but will include some discount schemes. Does the new plan make more sense? 北京正式公布了公共交通票价调整实施方案。和现行的全路网两元票价相比，调整后的北京地铁票价采用按里程分段计价，遵循加价"递远递减"的原则。
