Growth of MBTA Subway from 1888 -2023
Growth of MBTA Subway from 1888 -2023
The graph here shows how the MBTA has been developed since the year 1888-2023. The video includes buses, ferries and all the different subway lines in Boston.
1. Orange line: In 1904 the first ever subway named as Tremont Subway which starts from Dudley station to Sullivan station which is now known as the orange line MBTA was constructed. In 1908 the Orange line was re-built changing its alignments and in 1978 till date the Orange line services us Forest Hill to Oak Grove.
2. Red line: In 1912 red line being the second line of transport was built under the name Cambridge tunnel. In 1916 the first ever connection between two lines was seen. Ever since then 1988 Red line was fully established from Alewife to Braintree and Mattapan.
3. Blue Line: In 1924 blue line was formed as the third line which started from Bowdoin station. In 1955 till date the blue line has been built which service us from Bowdoin to wonderland station.
4. Green Line: In 1959 Green line was born under which the line D was first discovered from Riverside to Park Street. Along with this in 1967 three branch B, C, E where added. Green line is still in construction having Medford as the last new stop.

Average Travel Times for Fall - 2019
Average Travel Times for Fall - 2019
Travel Time for Weekdays Vs Weekends
Travel Time for Weekdays Vs Weekends
The connect dot plot uncovers station-specific travel patterns that represent the average travel time for weekday -peak and offpeak hours as well as weekend- peak hours. Each connected path represents the minimum and maximum time taken by the train to travel in seconds.
A wider spread indicates higher variability, while a narrower spread suggests more consistency. For weekdays, we've included both peak and off-peak travel times in our analysis to offer users a comprehensive understanding of transit dynamics throughout the week.
This dual perspective enables users to not only navigate the intensity of peak hours but also plan their journeys during less congested, off-peak periods, providing a more holistic view for optimized commuting choices.
In the series we have two charts expressing time caused by various train to reach its destination in peak and off-peak hours on weekdays and weekends
Key insights:
Weekend we see a substantial increase in travel time (around 700 seconds) from Symphony to Northeastern on the green line, significantly higher than the weekday average of 184 seconds. It may be a one-time variation as well.
Given the considerable distance between North Quincy and JFK/UMass, the extended travel times during weekday peak hours (760 seconds) likely result from a combination of both geographical distance and peak-hour congestion. On weekends, the slightly shorter travel time (629 seconds) may be influenced by reduced commuter traffic.
Percentile Travel Times between Stations
Percentile Travel Times between Stations
Each percentile on this graph represents the minimum and maximum travel times relative to the standard time.
The adjacent station's minimum arrival percentile time is denoted by the blue dots, while the red dot represents the maximum arrival percentile time.
The wide spread in the connection dot illustrates the distance between two neighboring platforms. A greater distance corresponds to a higher percentile range, while a shorter distance results in a smaller percentile range.
p05: The fifth percentile of time, in seconds, from departure at one station to arrival at the next adjacent station.
p95: The 95th percentile of time, in seconds, from departure at one station to arrival at the next adjacent station.
Here,
P05_sec = Number of Values below 0.05
P95_sec = Number of Values below 0.95
Standard Time = Total Number of Values
Noteworthy in Green-C is the significant spread between Kenmore - Saint Marys Street, and in Green-B, Kenmore - Fenway.
For the Blue, Orange, Red, and Mattapan lines, there's minimal variation in travel times, indicating consistent and stable transit performance.
However, the Green-D line exhibits a notable spread, notably between Kenmore and Fenway (112 to 668 seconds), possibly attributed to varying congestion levels.
External factors like adverse weather conditions and special events may contribute to these fluctuations.
Rapid Transit Predictions
Rapid Transit Predictions
Every bin in this graph's the either early or delayed time of arrival with respect to scheduled time of arrival. These are weekly reading based from 2020-2022. Here the bin 0-3 specify the most on time arrival of train and 12-30 min bin specify the most delayed/earlier arrival of the train.Comparing all the bins together arrival times are highly seen between 6-12 bin and 12-30 bin.
Key insights: :
Red Line Discrepancy: The Red Line is characterized by substantial delays observed within the 6-12 and 12-30 minute intervals. It demonstrates a commendable predictive accuracy of 90% across these time bins.
Mattapan Anomaly: There are big delays in the 6-12 minute time range, similar to the Red Line. Notably, the predictive accuracy remains steadfast at 90%, showing the system can reliably forecast despite these delays.
The Orange Line often experiences significant delays lasting 6-12 and 12-30 minutes. Despite these challenges, it shows impressive accuracy in predicting these delays, with a solid 90%, highlighting its strong ability to forecast despite changing time conditions.
Line-Specific Variations: The Blue, Green - E, C, D, and E lines exhibit similar arrival time variations across bins, the accuracy being very low which is 60-70%. However, Green B, possibly due to heightened demand and its connection to Boston University (BU), experiences slightly higher variations. The B Branch runs from Boston College to Government Center, catering to a substantial ridership, particularly from the academic community at BU.
Gated Station Entries
Gated Station Entries
Here, every tap at the gated entry is considered per person entering the station. This graph gives insights of maximum number of taps each month for the year 2022.
The graphical representation captures the monthly trend of gated entries across all transit lines. The x-axis denotes months, ranging from January to December, while the y-axis reflects the number of gated entries (in thousands).
The consistent pattern of seasonal variations in commuter activity across all transit lines underscores the impact of external factors on public transportation usage. The notable fluctuations, exemplified by peaks during winter months and declines in spring, reveal the sensitivity of transit patterns to weather conditions.
Key insights:
1. Blue line: The Maverick Gated entries show a substantial growth with 2,08,436 taps in December-January and has a sudden 87,893 in May, indicating a clear seasonal trend. Colder weather and holiday festivities likely boost transit use during December-January, while warmer weather in May, coupled with summer break, sees a decline as alternative transport modes like walking or biking become more appealing. Moreover, May often marks the end of the academic year and the onset of summer break, leading to a decline in commuter activity
2. Green line: Copley station entries on the Green Line reveals significant growth from January to June and than rises to the peak in September. This shift is likely due to incoming student every Fall year as Copley being the iconic and vibrant place in Boston. Additionally, April aligns with many academic spring breaks, potentially contributing to reduced station activity. Recognizing these seasonal dynamics is essential for optimizing transit planning, including weather-related strategies and adjustments based on academic calendars, ensuring an adaptable and efficient transit system.
3. Orange line: Back Bay entries show highest gated entries with a significant number of 1,86,056 in June and drop down to 62,146 in September. The rise of gated entries starts again in fall term with 167,792 in the month October.
