Vehicle Maintenancee MBTA measures in mean-miles between failures, the

erage distance a vehicle travels between breakdowns.

Schedule PerformanceThe MBTA measures reliability as the percentage of

heduled service operated. This measure captures our

bility to maintain the system well and operate reliably.

System MaintenanceA key measure of system maintenance is the travel time

impact of slowdowns caused by track condition. Impact is

measured as minutes of speed restrictions.

SafetyIncidents per 1,000 vehicle-miles traveled

Accidents / Incidents are t racked "per 1,000 vehicle-miles traveled" (or

per 100,000 passenger-miles traveled) to allow longer / more frequent

lines to be compared fairly against shorter / less frequent lines.

BudgetThe MBTA has set a goal of beating our operating budget

by 2% in FY2011. The following chart tracks progress

towards that goal.

On-Time PerformanceOn-Time performance is a key measure of commu

performance. A Commuter Rail train is considere

time if it arrives five minutes or less after the sch

time.

For Subway, On-Time Performance compares t

scheduled frequency of service to the actual frequ

About The Measures

Vehicle availability (Subway, Bus, Commuter Rail)Vehicle availability measures whether there are enough vehicles available to run all the service that

is scheduled each day. A vehicle might not be available if it has a mechanical problem or if it is

undergoing routine maintenance. Vehicle maintenance works to have enough buses and trainsavailable each day. The number of vehicles required for service varies seasonally and over time as

schedules change.

Mean Miles Between Failures (Subway, Bus, Commuter Rail)Mean Miles Between Failures (MMBF) measures vehicle reliability. It is the average number of miles

a vehicle travels between breakdowns. If one vehicle travels 5,000 miles in a month, and breaks

down twice during that time, that vehicle has an MMBF of 2,500. Values can fluctuate greatly from

month to month if the total number of failures is already small. High MMBF is achieved through

ongoing vehicle maintenance, which includes everything from oil changes to major midlife overhauls,

and by periodically buying new vehicles to replace old ones as they reach the end of their useful life.

Speed Restrictions (Subway)Speed restrictions measure the amount of slowdown caused by track conditions. If a section of trackfalls below standards in some way, such as if the rail is worn down, a speed restriction is put in place

to ensure safe operation. Trains operate at a reduced speed when traveling that section of track until

the issue is addressed. If the impact on the Orange Line for a month is three minutes, that means

that speed restrictions add three minutes to the fastest possible round trip. Trains dont actually

operate at the maximum speed allowed by track conditions at all times (they slow down to a stop to

pick up passengers, for instance) so the actual impact on travel time may be less than the

theoretical impact thats shown.

Percent of Scheduled Service Operated (Subway, Bus)Percent of Scheduled Service Operated shows the percentage of scheduled trips that the MBTA

operated. The MBTA strives to come as close as possible to operating every scheduled trip on every

day.

That requires having enough operators, well-maintained vehicles and track, and good schedules; and

also keeping a certain number of extra operators and vehicles on standby to fill in if theres a

problem. If a trip is nonetheless dropped on a frequent bus route or a subway line the MBTA will

spread out other trips on the route to try to fill the gap as much as possible. If theres no way to

avoid missing a trip on an infrequent bus route the MBTA will notify as many customers as it can via

T-Alerts, mbta.com, and the customer support hotline.

On the subway system the trains on standby are sometimes used to run extra trips, so more trips

may be operated than scheduled.

On-Time Performance (Subway, Commuter Rail)On-time performance (OTP) shows how well our service follows our schedules. For each type ofservice we measure on-time performance differently to reflect the way the customer experiences it.

Subway customers walk to the subway platform at any time and wait for the next train, expecting the

trains to run frequently. So the subway OTP standard compares the scheduled frequency of service

to the actual frequency. Trains must leave the first station within 150% of the scheduled interval

between them. If a Blue Line train is scheduled to leave Wonderland four minutes after the previous


12/12

train was scheduled to leave, and it leaves more than six minutes after the previous train left, then

the train is late.

Commuter Rail customers use a published schedule of trip times. A Commuter Rail train is

considered on time if it arrives four minutes or less after the scheduled time. The MBTA also

tracks how many trips are less than 10 minutes late, which includes trips that are not on time butare still relatively close to schedule.
