Mini Project 01: Fiscal Characteristics of Major US Public Transit System
Introduction
Public transit systems plays an important role in providing the essential transportation service for millions of residents in the United States. In this project, we are looking to analyze the fiscal characteristics of public transit systems to evaluate their financial performance.
Fiscal Characteristics:
We are going to analyze public transit systems based on the following:
Expenses: costs to operate (fuel, maintenance, employee salaries, etc)
Fare revenue: money earned from passenger fares
Farebox recovery ratio: how much of the operating expense is covered by the fares revenue (total farewell revenue/total operating expense)
I created the table using the code provided in the assignment instructions. In this code, I renamed “UZA Name” to “metro_area” (Task 1). I also modified the “Mode” column (Task 2) so we can understand the context of each abbrevations. The interpretation of the codes can be found on the NTD website in the glossary section.
I wanted to explore the monthly ridership trends of the public transit systems. Using the code below, I made a table that lists the top 5 months with the greatest percent change in monthly ridership.
library(dplyr)library(lubridate)monthly_ridership_change <- USAGE |>mutate(month =format(ymd(month), "%Y-%m")) |>group_by(month) |>summarize(total_upt =sum(UPT, na.rm =TRUE), .groups ='drop') |>arrange(month) |>mutate(percent_change = (total_upt -lag(total_upt)) /lag(total_upt) *100)# take the top 5 months that shows the greatest percent changetop_5_months <- monthly_ridership_change |>filter(!is.na(percent_change)) |>arrange(desc(percent_change)) |>slice_head(n =5) top_5_months |>gt() |>tab_header(title ="Top 5 Months with Greatest Percent Change in Ridership")

Findings:
2020-06 (29.76% Increase) and 2020-07 (20.04% Increase): Due to quarantine requirements in early 2020, public transit usage has rapidly declined. In June 2020, as the restrictions loosened, and hence we see rebound in passenger usage of public transit with approximately 30% increase in usage. Passenger usage continue to grow a 20% increase in July 2020. Also, this growth can reflect seasonal factors since July is one of the peak seasons for summer vacation. People are regular to their regular routine and planning for vacations.
2021-03 (27.34% Increase) and 2022-03 (20.37% Increase): These period reflects the ongoing recovery of the COVID-19 pandemic. Reopening of business, end of remote working modes, loosen of public health safety measures encourage more rider usage of public transit. Hence, we see a relatively big increase in ridership usage.
Unlinked Passenger Trips per Vehicle Revenue Miles
I also wanted to explore the ratio of unlinked passenger trips per vehicle revenue miles to evaluate the efficiency of transit systems. Using the code below, I categorized and ranked 18 transit modes by the UPT per VRM ratio. The UPT per VRM evaluates how many passenger trips is generated per vehicle mile.
Agencies have different transit modes. I want to analyze which transit mode has the highest UPT for each agency. For example, King County has transit modes of ferry boats, bus, demand response, etc. I want to explore which transit modes in King County generates the highest VRM. Using the code below, I generated the top 3 highest VRM transit mode for each agency.
Los Angeles County Metropolitan Transportation Authority
Bus
3501202902
Findings:
The highest transit mode for MTA New York City Transit agency is heavy rail. It generates 7,732,916,753 miles. Recall in question 1 of Task 3, MTA New York City Transit has a total of 10,832,855,350 miles in total. If we calculate the percentage of total VRM operated by heavy rail, we get 71.4%. Heavy rails operates a big portion of the vehicle miles travelled by MTA.
Note: For Task 6 questions, the output table will show the top 5 results.
1. Which transit system (agency and mode) had the most UPT in 2022?
In 2022, the MTA New York City Transit heavy rail has the great number of passenger trips. It has over 1.7 billion trips.

Conclusion
The metrics to analyze the most efficient transit system can be measured in different ways.
Looking at the farebox recovery ratio, Port Imperial Ferry Corporation ferry boat would be the top candidate as it can shows a strong ratio of 1.428 (refer back to Task 6 question 2). This shows that Port Imperial Ferry Corporation ferry boat has strong profitability and has a healthy financial performance.
If we measure efficiency from vehicle miles, MTA New York City Transit Heavy Rail would be the most efficient transit system. It has the highest vehicle miles travelled (refer to question 1 of Task 3). It provides extensive amount of service indicating high ridership demand. Its vehicles are well utilized and therefore operating efficiently.
