Battery-powered buses are driven with traction motors run by electricity. Motors can indirectly convert fuel energy into driving forces extremely efficiently by consuming electricity that is generated from fuel by a power plant in a normal way. Thus, motor traction saves energy compared with engine
traction, which burns fuel directly. In addition, battery-powered buses emit no pollutants or GHGs into the atmosphere (see Annex C, which shows a typical application of battery-powered buses in a city). Furthermore, traction motors enable buses to run quietly with little irritating vibration. This
enables battery- powered buses to maintain a good environment for those living near bus routes, while providing onboard passengers with good ride comfort through continuously varying acceleration. This cannot be accomplished by internal combustion engine systems, which create uncomfortable jolting
during gear changes. One of the goals of smart transportation is not to disturb current service performance and quality, but rather improve it further compared with conventional services. No changes should be made to current operating systems, including working schedules, dispatching and facilities related to internal-combustion-engine-driven bus operations, both during and after the introduction of smart transportation. Smart transportation aims to solve the issues of air pollution from GHGs and irritation to citizens from noise and vibration in cities and should also contribute to the further development of cities by satisfying the purposes designated in ISO 37101:2016.Smart transportation in the form of battery-powered bus operation solves specific city issues as mentioned in Clause 4 by retaining the same operation, services and facilities as those already in place for internal-combustion-engine-driven bus operation when some of the buses are replaced with battery-powered buses. When all internal-combustion-engine-driven buses in service are replaced, or when battery-powered buses are newly installed in an area where no bus operation has been in service, it is not necessary to follow the requirements given in 5.2.1 to 5.2.4, 5.2.7 and 5.2.8. Battery-powered buses shall, however, be operated according to the requirements specified in 5.2.5, 5.2.6 and 5.2.9.BS ISO 37158 pdf download.
