4 General 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 [2] . 5 Operation of smart transportation using battery-powered buses 5.1 General 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. 5.2 Minimum requirements to organize smart transportation 5.2.1 Recharging Recharging work shall be completed within the same working schedules as those applied to current internal-combustion-engine-driven bus operation in the replacement with battery-powered buses. Allocate recharging work to refuelling work time or stand-by time for the next turn-back operation at a terminal. Electrical capacity shall be capable of supporting battery-powered bus recharging. Cities can implement renewable energy as one of the options for recharging (see Table B.2). 5.2.2 Scheduling/dispatching Operation scheduling and bus dispatching shall be organized to permit current internal-combustion- engine-driven bus operation even when it is partly or entirely replaced with battery-powered bus operation. 5.2.3 Maintenance work To the maximum extent practical, all maintenance work, such as cleaning, inspecting and overhauling bus vehicles, shall be completed in the same working schedules as for current maintenance work for internal-combustion-engine-driven buses, for replacement with battery-powered buses. 5.2.4 Passenger services All passenger services, including fare payment, in-/out-coming, coach accommodations and passenger capacity, shall be neither inconvenient nor poorer than those currently organized when replaced with battery-powered buses.BS ISO 37158 pdf download.
