These buses, on average, use 4 liters of diesel (柴油) fuel to travel less than 16 kilometers. When the school year began last fall, diesel averaged 55 cents a liter nationally. The price nearly doubled by the end of school in June.
Bob Riley is the spokesman for the American School Bus Council. He says fuel prices negotiated(商议) for schools are not lower than others have to pay. As a result, schools are looking for ways to reduce transportation costs. Bus routes are being redrawn or, in some cases, canceled. Some areas are buying buses that use natural gas or other alternative fuels.
Other steps include fewer field trips and less travel by sports teams. Some school districts may end any bus service not required by law.
Studies show that school buses are the safest form of transportation to and from school.
The American School Bus Council says cuts in bus service are bad for children and possibly the environment. It says removing buses from the road will mean an increase in other vehicles transporting students. Spokesman Bob Riley says another concern is that reducing
bus service might reduce attendance.
It could also get more children to walk or bicycle to school. That would surely make people happy at the National Center for Safe Routes to School. More kids walking or biking safely to school is the aim of a 3-year-old federal program, part of an international movement. The goal is to increase physical activity and reduce air pollution.
