TCRP PROJECT J-7, SYNTHESIS TOPIC SA-32 SYSTEM-SPECIFIC SPARE BUS RATIO UPDATE
The following tables summarize the detailed responses to a survey of current practices on System-Specific Spare Bus Ratios, as part of TCRP Synthesis SA-32: System Specific Spare Bus Ratio Update. The purpose of this synthesis is to update the findings of the Transit Cooperative Research Program (TCRP) Synthesis No. 11 on Spare Bus Ratio practices, published in 1995. Since then, the challenges facing transit operators have changed dramatically, becoming increasingly more complex. The TCRP Synthesis SA-32 report provides information on various factors affecting bus spare ratio levels, and agency approaches taken to reduce their spare ratios and the results.
Please refer to the report, TCRP Synthesis SA-32: System Specific Spare Bus Ratio Update for the full list of survey questions (see Appendix A) and the findings.

64 Yes. Newer technologies at an Agency typically require additional resources, new / advanced skills sets for the Mechanics, lack reliability and cause a need for contingencies. This contingency fleet requires service and maintenance regardless of the actual amount of time or miles used. From a cost per / XX basis, it can become an expensive and resource draining insurance policy.

Yes. We have a very diverse fleet, including three different fuel types: ultra low sulfur diesel, CNG, and hybrid diesel-electric. The CNG buses require specialized fueling stations, whereas the diesel and hybrid buses do not. Therefore, CNG buses can only be assigned to two of our depots. When adjustments to the spare factor are made, these constraints are taken into consideration.

Yes. Different types of service require different types of vehicles. Each vehicle type needs to maintain a spare ratio for that type of service. Example: you can’t place an articulated bus on a route that requires a 35 foot bus due to terrain and tight turns or other size constraints. And in the same principal, you can't place a 35 bus on a dedicated bus way. You could, but your customer complaints would shoot through the roof due to the passengers left standing at the curb. The goal of public transit is to get the riders from point A to point B, not leave them standing at the curb. That being said, each fleet/service type needs to maintain a corresponding spare ratio.
High passenger carrying capacity; ability to maneuver in confined areas; premium seating/ amenities; more than one door; more than two doors.
Yes. If you are short on 35 foot buses due to maintenance. The operator will have to wait for one to return from service and leave the division late for his run. Also, there may be a need to send a 40 foot bus on an articulated bus run if not enough are available at a particular operating division.

Yes. BRT and Electric Trolley Bus (ETB) Fleet carry some risk of running with high spare ratios. We has a long history with ETBs and occasionally encounters periods where a portion of the fleet must be dieselized, resulting in higher than necessary spares. BRT service has been launched more recently with the intent of no interlining and no coach substitution that would result in unbranded coaches

Yes. As stated in the response to question 8, the spare factor is adjusted based on many factors for each depot, including the type of transit service. For example, artic fleets for the Select Bus Service (SBS) have a higher spare ratio (20%), instead of the usual 15% since those buses have a specialty wrap. Also, some buses are used to provide airport service and have luggage racks. Those also have the higher 20% spare factor.

The useful life of a bus is 12 years. NYCT DOB performs Preventive Maintenance operations on its fleet of buses based on mileage and duty cycle. Local buses undergo a Scheduled Operations (S.O.) inspection after 3,000 miles or 4,000 miles. All express buses undergo an S.O. after 6,000 miles. Mileage readings used to calculate the maintenance interval are obtained from the vehicle’s hub-odometer. S.O. inspections are completed within a 500-mile window. This allows for flexibility in scheduling and even distribution of workload. In addition, the buses

Major Mechanic System Failures These are failures of a mechanical element of the revenue vehicle that prevents the vehicle from completing a scheduled revenue trip or from starting the next scheduled revenue trip because actual movement is limited or because of safety concerns. Examples of major bus failures include breakdown of air equipment, brakes, doors, engine cooling system, steering and front axle, rear axle and suspension and torque converters. Other Mechanical System Failures These are failures of some other mechanical element of the revenue vehicle that, because of local agency policy, prevents the revenue vehicle from completing a scheduled revenue trip or from starting the next scheduled revenue trip even though the vehicle is physically able to continue in revenue service. Examples of other bus failures include breakdowns of fireboxes, wheelchair lifts, heating, ventilation and air conditioning (HVAC) systems and other problems not included as a major mechanical systems failure.

ratio? A Yes I do not think it practical to reduce the ratio. B No With only 29 Buses and 19 Demand Response buses, that is
2.9 and 1.9 respectively; to keep up with required PMs and have spares, more buses are needed to achieve this goal.
Local sources of funding to assist with fleet replacement and expansion.
C No. We are too small and underfunded to get by with 20% Ability to replace vehicles at the end of their useful life as opposed to keeping vehicles until replacement funding is found.
D No Use of an annual conditional waiver. We have been tirelessly working to change the federal spare ratio requirements for the past 4 years. We have assembled an excellent working professional team and we have APTA approval. We have discussed all elements of the proposed recommendations with the FTA. We continue to wait for FTA acknowledgement and additional meetings to move our solid recommendations forward. This rule must change or continue to experience erosion and inefficiencies in public transit operations.
There are advanced recommendations already proposed. Introduction and Purpose The Federal Transit Administration’s (FTA) Spare Ratio policy has been in place since approximately 1964, leaving this rule without a major review in over 45 years. During this time period, the technological and operational characteristics of public transit buses, on which this rule was originally developed, have evolved drastically. Over the past three years APTA has reviewed transit requirements and is proposing a change to the 20% Spare Ratio Rule given today’s advanced technological environment. Background Public transit has evolved substantially over the last 4 decades, particularly in terms of fuel types and propulsion systems, vehicle lengths, vehicle configurations, intelligent transportation systems and the advent of new customer amenities on board the bus. Taken together, these changes have produced a much more technologically complex transit bus which exponentially increases the requirements for maintenance, asset management and challenges workforce training and

Is a 20% Spare Ratio realistic for
your agency? If not, why not?
Any changes in practice policy and/or resources you’d like to see toward improving ability to reduce spare
ratio? development in order to meet daily operational requirements. Summary of Impacts The increased diversity in fleet mix has greatly impacted the ability of transit agencies to operate within the 20% limit and still provide outstanding (revenue) services to our customers. Today’s fleets range in size (30 foot to 60+ foot), in layouts (including single, dual and triple doors), branding options such as BRT and even Double Decker buses. Each style of bus requires modifications to our maintenance and operational programs and thus more training to our workforce. The different buses are usually not interchangeable on the various routes operated by our systems, therefore requiring changes to asset management plans. The introduction of new fuel/energy technologies also impacts the ability to operate within the 20% (maximum) ratio policy. These technologies require longer repair and preventative maintenance downtimes, longer lead times for specialized parts and more experienced training for technicians in addition to changes in service schedules. Maintenance practices for advanced technology systems demonstrate that vehicle service and repair procedures are extended due the nature of these highly complicated systems. They further require a much higher level of technical education, proficiency and expertise, particularly in the diagnostic procedures and electronic systems repair. Examples of these technologies are Compressed Natural Gas, Liquefied Natural Gas, Electric Hybrid Technologies, Hydrogen Fuel Cells and Electric Battery powered propulsion systems. These environmentally sensitive technologies are extremely complicated and require non-traditional repair parts and highly skilled labor forces to maintain and repair these vehicles. The implementation of advanced electronic technologies that improve our customer service performance greatly impacts the ability to operate within the 20% limit. These technologies may include on-board Wi-Fi, advanced

Is a 20% Spare Ratio realistic for
your agency? If not, why not?
Any changes in practice policy and/or resources you’d like to see toward improving ability to reduce spare
ratio? electronics in fare media, vehicle location technology (smart bus systems), special ADA equipment and even emission reduction control systems that continue to evolve in response to air quality mandates and changing service requirements. The service mixes and interchangeability limitations between sub-fleets impact transit systems in meeting daily pullout requirements. When the rule was written most transit properties operated the same type of transit bus. Now we have diverse mixed fleets, even buses that are branded differently from the regular services like BRT, shuttle services, downtown-circulators, etc., which greatly impacts the ability to ensure the right bus is available for the prescribed service all the while meeting customer and system requirements, including the 20% rule. The introduction of special Customer Service Transit Initiatives, such as Bus Rapid Transit (BRT) service lines, creates a new specific set of operational demands that greatly exacerbates the spare ratio problem of the transit system. These buses are painted and branded differently from the standard bus fleet. BRT programs, effectively create a mini-sub-fleet within a transit property, creating a unique inventory with its own dedicated spare buses. This specialty fleet of buses can no longer be deployed into traditional transit service routes and are exclusively used for rapid transit service lines which greatly enhance customer ridership initiatives. Conclusion The evolution of these changes to the business of public transit have challenged maintenance programs to schedule and account for sufficient time to maintain, service, and fuel their fleets, and all sub-fleets within an eight (8) hour (system average) window to ensure daily revenue service is met. The specialized training and theory of our workforce is extensive and takes time and resources to develop and deliver. As our aging workforce is replaced, the hiring of new journey technicians that comprehend the different advanced technologies is extremely

Any changes in practice policy and/or resources you’d like to see toward improving ability to reduce spare
ratio? difficult. Once hired and trained, we then face technician retention problems. Through our US industry survey and exhaustive study, we have concluded that a change in the spare ratio rule is necessary and will greatly relieve the pressures on transit systems to meet our service efficiencies and requirements. The ability to maintain the appropriate number of spare buses as determined and documented by each agency will give us the time to maintain and keep them in safe revenue service. It will provide the necessary time to employ and train our technicians and even transit bus operators. It will further provide us with the ability and opportunity to create an appropriate asset management plan and maintain our assets in a state of good repair. Following is the summary of recommendations. 1. Fewer Than 50 Buses a. No change to the current policy b. No established maximum spare ratio c. No spare bus reporting required 2. 50 To 250 Buses a. No established maximum spare ratio b. Annual Spare Bus Declaration Report c. No report required if the spare ratio is less than 25% d. 25% spare ratio 3. More Than 250 Buses a. 25% Spare ratio for transit vehicles 35-feet in length and longer b. If exceed 25%, will need to submit a Bus Fleet Management Plan c. Small bus and non-diesel powered will be exempted from a spare ratio concerning the number of buses to be included in the calculation of the spare ratio, other exemptions and recommendations include: Nine-month period for old/new transition review; Clarification of policy exemption for demand-response vehicles and trolley buses; Buses less than 35 feet in length would be excluded when calculating the spare ratio; Buses with non-diesel propulsion systems would be excluded when calculating the spare ratio; buses being replaced by newly-procured buses would be excluded for a defined period of time when calculating the spare bus ratio; demand-responsive fleets, regardless of equipment used or fleet size, would be excluded

Is a 20% Spare Ratio realistic for
your agency? If not, why not?
Any changes in practice policy and/or resources you’d like to see toward improving ability to reduce spare
ratio? when calculating the spare bus ratio; trolley bus fleets (powered by overhead electric catenary system) would be excluded when calculating the spare bus ratio; seasonal fleets would be excluded when calculating the spare bus ratio. Specific fixed-route subfleets would be excluded when calculating the fleet-wide spare ratio, such as experimental vehicles being tested in revenue service; fleets designated as having manufacturer fleet defects would be excluded when calculating the spare bus ratio; buses operating in revenue service that have reached the end of their federally-defined minimum useful life would be excluded when calculating the spare ratio; buses not needed as a result of service cuts (for financial reasons) would be excluded when calculating the spare ratio, if those vehicles would be necessary to restore service when financial conditions improve. The Annual Spare Bus Declaration Report would consist of a current and projected inventory of buses in the agency fleet, by sub-fleet, and a high-level description of the service and maintenance demands of each fleet/subfleet. The Bus Fleet Management Plan would be a more extensive document intended to document and justify the fleet’s peak and spare vehicle levels, to be evaluated by the FTA for compliance, reasonableness of application, and operational efficiencies. The 25% spare ratio change would be a reasonable level to recommend with potential flexibility beyond this percentage as evaluated. The service profiles and interchangeability considerations would be important elements to include in the annual report by documenting the spare ratio requirements with basis. There may be a need for more flexibility in spare ratios to meet unique operational needs and local conditions.
E Yes We will soon be receiving new 40-foot buses that will allow us to retire the older buses that break down more often.
F Yes With a fleet this small the 20% is a very good ratio.

Is a 20% Spare Ratio realistic for
your agency? If not, why not?
Any changes in practice policy and/or resources you’d like to see toward improving ability to reduce spare
ratio? G No New Exhaust tech. now requires more time and routine
service, new bus replacements funding is not able provide replacements so we are operating old buses longer and with us the oldest buses are still operating 60% of our scheduled daily work.
More employees to perform maintenance, improved and sustained funding to provide replacement buses within the 12 year cycle.
H No. With added vehicle support system such as security, vehicle location systems, radio system, passenger counting systems, fare collection systems, etc, make it difficult to maintain and operate within the 20% spare ratio.
I don't think that additional resources would improve the spare ratio. I believe with specialized use fleets and all the new emissions and technologies it will create the opposite in needing an increase of spare ratios.
I Yes Parts availability and mechanical know-how J No Reduced fleet size, more mile generated, lack of qualified
technicians, corrosion problems, need for vehicle repairs by smaller garages, these all represent more vehicles for bigger repairs.
The definition for small properties (50 or <) should be expanded to mid-sized properties serving non-UZA properties. In addition, todays fleet technology must be taken into consideration.
K No Cannot get sufficient funding to support the spare ratio Improved training for maintenace staff and resources to do so. L No. Need to improve reliability of gasoline hbyrid fleet
(although mfg is bankrupt), need redundant support for CNG, and need to increase manpower (operating costs).
Stabilize alt fuels, advanced technologies (gasoline hybrids) and flat / predictable bus replacement strategy. Increased commonality in buses, bus technologies and minimize uncommonality between sites. Maintain all staffing positions as "filled", Mechanic, Supervisors, etc. Minimize need of continuous practice of having a contingency fleet.
M No Too often we struggle to make pullout due to technology issues; having an extra 3% spares would help keep us from missing pull on occasion.
FTA policy to limit at 20% should change to 23%.
N No Difficult to maintain maintenance requirements. Keeping buses no longer than 12 years/500,000 miles O Yes Proactive maintenance P No We run a Trolley system. If the system goes down or we
have to take it down for construction 20% will not cover it. NR

your agency? If not, why not?
Any changes in practice policy and/or resources you’d like to see toward improving ability to reduce spare
ratio? Q Yes We are able to meet the 20% spare ratio and operate with a
slightly smaller spare ratio. Vehicle reliability is the key factor to maintain buses in service therefore minimize the need for a larger spare ratio. Since Samtrans does not have specialty vehicles for specific routes, there is no urgency to meet pull-out due to limited buses. Our operating principle is to have as much interchangeability to allow flexibility in order to meet service demands.
R No Each service type has its own unique operating characteristics, maintenance demands, and, in many case, specialized vehicle and accessory requirements. Consequently, to fully meet the needs of the range of service types offered by the RTC, the spare ratio must be sufficient within the subfleet(s) of vehicles that support each service type. All buses in the entire fleet are not necessarily interchangeable in their ability to support all service types.
Spare ratio calculated by sub-fleet type.
S Yes NR T No If applied to sub-fleets, then yes. Apply spare ratio to sub-fleets U Is 20% SR
realistic for your agency?
If not, why not Changes in practice policy add resource you’d like to see toward improving ability to reduce spare ratio.
V No Issues with engine manufacturers, increased amount of time to maintain high tech systems, lower staffing levels
Raise the required 20% Spare Ratio, and increase Federal funding.
W Yes NR X Yes At the moment, I do not believe it possible to achieve
substantive reductions in the current spares ratio. On a daily basis, dispatch needs are being met with under five spare buses, on extremely cold days when the number of buses unavailable for service exceeds approximately 40 buses, up to five runs must be cancelled or dispatched late on well serviced routes.

advancement reducing workforce skill-set. Training vehicles to be excluded in active quantity.
Z Yes Reduce average age of fleet from 11 years to 8 years would go a long way.
AA Yes 1. Allow for spare ratios calculated at the sub fleet level defined by different vehicle configurations or applications; 2. Allow for spare ratio fluctuations due to changes in service delivery quantities and requirements during useful life of vehicles in fleet; 3. Allow for spare ratio realignment through vehicle replacement plans; and, 4. Respond to authority requests for spare ratio deviations.
BB No Bus technologies, increased requirements for new pm and repair procedures on an increasingly technical vehicle. Reduced maintenance staffing. Average age of fleet and duty cycle. Aged facilities not as accessible for our growing Articulated fleets.
Improved/upgraded facilities. Increased manpower. Technology training. The ability to get the fleet to a six year average age of fleet.
CC No More and more specific service types demanding specific types of buses.
NR
DD No Due to the amount of rail diversions resulting in shuttles the maintenance needs have increased.
Additional staffing would assist in reducing the OOS time.
EE No With low numbers of technicians, harsh winters and increasing maintenance challenges.
There need to be a balance between investing and replacing buses and in better fully staffed facilities
FF No Demands for special service, bus retrofits, advanced tech equipment installation; Accelerated structural problems due to bus design, use of freeze protection chemicals on streets; advanced technology equipment requires higher level of maintenance knowledge and added maintenance requirements.
Uniform fleet of buses. Added qualified mechanics to work on buses with advanced technologies.

basis and will continue to monitor going forward. maintenance diagnostics, implementation of standard times, annual employee expectations, etc.
HH No Advanced Propulsion Technologies; Multiple fleet Mix to support service designs; Advanced Technologies, i.e. CAD, AVL, GPS, Customer Info Sign, etc.
Changes to reduce our current spare ratio can include the impacts of facility capacity, staff levels, overtime, comp time, internal job functions vs. external, staff productivity, inventory levels, inventory cycle counts, vehicle in service time, vehicle technical complexities, cleaning cycles, PM cycles and planned vs. unplanned maintenance etc.
II Yes As our average fleet age will start to rise again, our goal is to maintain the actual fleet spare ratio of 17%. Increasing the productivity of our staff and the efficiency of our operations and PM is currently the avenue taken.
JJ No. The 20% spare ratio is currently viewed as being too large. We believe in minimum spare ratio with which to cost affectively operate the fleet.
1. Steady state funding for timely bus replacement and overhaul. 2. Improved vehicle performance and reliability 3. Increased training resources.
KK Yes Currently using existing resources to complete a focused review of bus availability and reliability to investigate opportunities to improve fleet availability and reliability.
LL Yes Changes in the CBA that would provide for part time maintenance staff or swing shifts
MM No Specialty fleets operate with a 20% spare factor, but overall we operate with a baseline spare factor of 15%.
As stated above, the spare ratio already takes into account many factors. Any improvement in fleet reliability, increase in maintenance skill set resources, or change in duty cycle would allow NYCT to have a lower spare ratio. Also, increase in funding for new bus purchases would allow us to reduce our spare ratio since newer buses are more reliable than buses at the end of their useful life.
