The advantage of hybrids, which combine small, efficient diesel engines with battery-powered motors, is that they can increase fuel mileage significantly while reducing emissions. The main disadvantage is the higher upfront cost for the vehicles, which cost about twice as much as a standard diesel-powered bus. If hybrid buses become popular and are produced in volume, the cost will come down, but there will always be a premium to be paid. Unless government subsidies are available to offset those costs, school districts will be reluctant to pay the premium.
About one in five respondents (20.4 percent) believe that hydrogen fuel-cell buses will replace diesel buses by 2056. This alternative-fuel system is already being used in a few transit buses, but, again, the initial cost of the bus and the fueling infrastructure is prohibitively expensive. One of the hydrogen-powered hybrid buses operated by AC Transit in Oakland, Calif., cost more than $1 million to manufacture.
Electric bus has appeal
About one in eight (13.0 percent) of respondents believe that pure electric buses are the wave of the future. A few attempts to run electric school buses have met with failure, but scientists are continuing to research and develop more efficient battery systems. The biggest hurdle has been the limited range of the buses and the weight of the battery packs. If scientists can develop lighter, more efficient and more affordable batteries, it’s possible that school buses that cover shorter routes could run solely on electricity.
Some of the respondents believe the status quo will prevail. About 17 percent said diesel fuel will continue to dominate the industry over the next 50 years. They more than likely believe that fuel prices will stabilize and that concerns about the depletion of the world’s oil supply are unfounded.
About one in 20 respondents (5.6 percent) believe that natural gas will take over where diesel leaves off. Some California school districts operate compressed natural gas (CNG) buses, but the results have been mixed. Without government grants to cover the additional cost of CNG buses and their fueling stations, however, few of the districts would be able to afford them.
Buckling the trend?
To understand how the industry views the future of crash protection, our survey asked whether respondents believe that active restraint systems such as lap-shoulder belts will be standard on all school buses in 2056.
Surprisingly, less than two-thirds of the respondents (61.1 percent) say yes. More than a third (35.2 percent) say no, while 3.7 percent are unsure.
California already has such a law on the books, and other states are seriously considering similar statutes.
Compartmentalization has been the underpinning of an amazing safety story for the past 30 or so years, but the public will continue to ask the obvious question: “If automobiles are required to have three-point belt systems, why aren’t school buses also equipped with them?”
Studies sponsored by the National Highway Traffic Safety Administration suggest that installation and use of lap-shoulder belts would have an almost imperceptible impact on fatality rates in school bus accidents, but the reality is that the public doesn’t really care about federal studies when it comes to an emotional issue such as child safety.
Where do I stand?
I believe it’s likely that school bus-based pupil transportation will progressively diminish over the next 50 years. By 2056, school buses will be used to transport special-needs students and students in rural and suburban areas that live long distances from their schools.
California provides a glimpse into the future. In the Golden State, the percentage of students eligible to receive school bus transportation has diminished to just 17 percent. Most of those who do receive transportation are special-needs students. Many students, especially the older ones, who aren’t eligible to ride a school bus use public transportation to get to school.
An increase in the use of public transit — buses and trains — is a trend that I think will continue over the next five decades. With budget problems likely to continue, school boards are going to look seriously at the low-cost alternative of public transportation. And transit systems, always on the lookout for ways to increase ridership, will be more than happy to accommodate school districts that are willing to face the possible political fallout of putting students on buses that aren’t yellow.
I think it’s important for the pupil transportation industry to learn from its transit brethren. The transit industry does a great job in telling its story, about how it helps to provide communities with mobility options, to reduce congestion, to mitigate air pollution, to create jobs and to stimulate the economy. The pupil transportation industry can make the same claims, and add that it’s the safest form of surface transportation!
The fuel of the future
In regard to fuel, I’m going to sit on the fence here. Hybrid diesel-electric buses are too expensive for all but the most heavily funded school districts, but the technology seems appropriate to the task. These hybrids use regenerative braking to help recharge the battery systems. The stop-and-go driving of school buses fits this application perfectly.
Whether or not we’re going to deplete the global supply of crude oil is an open question that even the most astute geologists can’t answer with certainty. We must, however, not wait before starting a serious search for fossil-fuel alternatives. The growing popularity of biodiesel is a positive development. It’s too soon to say whether biodiesel will play a significant role in reducing our dependence on fossil fuels, but the mere fact that fleets are willing to try biodiesel is a good sign.
While the transportation industry gains practical experience with the readily available alternative fuels, we need to ensure that we’re doing our best to conserve the fuels that we’re using. Reducing idling times, optimizing routing and scheduling, and keeping buses in top operating condition will help to slow down the depletion of our fuel supply. That’s an important consideration in the short term, especially with volatile fuel prices, and in the long term, as we consider the possibility that Hubbert may have been correct.
A virtual classroom?
I don’t think we’ll see wide-scale use of virtual classrooms that allow students to learn from home over their computers. Even if the technology becomes cheap and available to even the lowest-income families, the value of academic learning is wholly diminished if it is not accompanied by social development. You can have a virtual classroom, but I don’t think we’re ever going to have virtual dances, football games or food fights. It’s just not the American way.
Besides, if distance-learning becomes the norm, there won’t be a need for school buses or for trade magazines that cover the school bus industry. And we are hoping to be around in 2056 and beyond!
