However, transit bus companies in these countries are often cash-strapped. In many cases, the operating cost per bus kilometer exceeds revenues and bus fares are often kept low irrespective of the cost of providing service. Many cities are dominated by old and fuel-intensive buses with high operating costs. Transit systems are also often plagued by overcrowded and undependable service, congested roadways and chaotic operating environments. Across the board, city officials in developing countries are under strong pressure to improve the efficiency and enhance the attractiveness of bus transportation. Fuel makes up a relatively large fraction of total bus operating costs, especially when labor costs are low, as in many developing countries. Fuel costs can be reduced by improving the driving style of bus drivers and through sound maintenance practices. A safe and economical driving style can reduce variable costs, decrease down time due to repair work and maintenance, mitigate negative environmental impacts and improve road safety. This guidance note1 provides detailed and practical recommendations on how city bus operations managers and their technical staff can plan and implement such enhancements to their fleets through Operations and Maintenance (O and M) practices without significant capital investments. By implementing such recommendations, municipal officials and bus operators can increase the efficiency and fuel economy of their bus systems and reduce their cities' energy consumption, congestion and pollution. This guidance note provides detailed and practical recommendations on how city bus operations managers and their technical staff can plan and implement such enhancements to their fleets through O and M practices without significant capital investments.en-USCC BY 3.0 IGOACCELERATIONACCELERATOR PEDALAIRAIR CLEANERAIR CONDITIONERAIR FILTERSAMBIENT TEMPERATUREAUTO MANUFACTURERSAUTOMATIC VEHICLE LOCATIONAXLESBLACK SMOKEBRAKESBUS AVAILABILITYBUS COMPANIESBUS COMPANYBUS COSTSBUS DATABUS DEPOTSBUS DRIVERSBUS FARESBUS FLEETBUS OPERATINGBUS OPERATING COMPANIESBUS OPERATING COSTSBUS OPERATIONSBUS OPERATORBUS PASSENGERBUS REPLACEMENTBUS ROUTEBUS SERVICESBUS SYSTEMSBUS TRANSITBUS TRANSPORTBUS TRANSPORTATIONBUS TRAVELBUS TYPEBUSESCAPITAL INVESTMENTCARCARBON MONOXIDECARSCERTIFICATION LEVELSCITY BUSCITY TRANSITCLEAN DIESELCLIMATE CHANGECLOGGINGCLUTCHCOMPRESSED NATURAL GASCONGESTIONCORROSIONCOST-BENEFIT ANALYSISCYCLINGDAILY TRAVELDIESELDIESEL BUSDIESEL SOOTDRIVER BEHAVIORDRIVER EDUCATIONDRIVER TRAININGDRIVINGDRIVING CONDITIONSDRIVING STYLEELECTRONIC CONTROL SYSTEMEMISSIONEMISSION CERTIFICATIONEMISSION STANDARDSEMISSIONSENERGY CONSUMPTIONENERGY EFFICIENCYENGINEENVIRONMENTAL IMPACTSEXHAUST EMISSIONSEXHAUST PIPEEXHAUST SYSTEMEXPENDITURES ON FUELFILTERSFIXED COSTSFLEET MANAGEMENTFLEET OPERATORSFLEET SIZEFUELFUEL CONSUMPTIONFUEL COSTFUEL ECONOMYFUEL ECONOMY IMPROVEMENTFUEL EFFICIENCYFUEL EFFICIENCY DATAFUEL INJECTIONFUEL SAVINGSFUEL USEFUEL-EFFICIENT DRIVINGFUELSGARAGESGAS PRESSUREGLOBAL CLIMATE CHANGEHEAVY DUTY VEHICLESHYDROCARBONSINJECTION NOZZLEINJECTION PUMPINJECTION TIMINGINSPECTIONMILEAGEMOBILITYNATURAL GAS BUSESNOISEODOMETERPARTICULATE MATTERPASSENGER CAPACITYPERIODIC MAINTENANCEPOLLUTIONPRIVATE OPERATORSPRIVATE VEHICLEPRIVATE VEHICLE OWNERSHIPPUBLIC SAFETYPUBLIC TRANSITPUBLIC TRANSPORTPUBLIC TRANSPORT SERVICESPUBLIC TRANSPORTATIONRAPID BUSRIDERROADROAD SAFETYROAD TRANSPORTROADWAYSROUTESAFE DRIVINGSHARINGSMOKE OPACITYSPARK PLUGSSPEEDSSTRUCTURESSUSTAINABLE TRANSPORTTEMPERATURETIRESTRAIN DRIVERSTRANSITTRANSIT ADMINISTRATIONTRANSIT AGENCYTRANSIT AUTHORITIESTRANSIT AUTHORITYTRANSIT BUSTRANSIT OPERATIONSTRANSIT SYSTEMSTRANSPORT AUTHORITIESTRANSPORT RESEARCHTRANSPORT SECTORTRANSPORT SYSTEMSTRANSPORTATION FARESTRANSPORTATION RESEARCHTRIPSTRUEURBAN BUSURBAN BUS TRANSITURBAN PUBLIC TRANSPORTURBAN TRANSITURBAN TRANSPORTATIONURBAN TRAVELERSURBANIZATIONVEHICLE EMISSIONSVEHICLE FLEETSVEHICLE MODELVEHICLESVIBRATIONWALKINGWHEELSReportWorld Bank10.1596/26529
