Transit Frequency

Transit Frequency measures the number of times a bus or train is scheduled to stop (trips) at a transit stop in the St. Louis region as part of its weekday or weekend route. The more trips there are, the shorter the wait time between trips and the more alternative routes a person has to get to their destination. There are over 93 million trips annually in the St. Louis area, which equates to over 271,000 trips per census tract.

Data Note: There are 106 census tracts within the City of St. Louis, but Bi-State data included only 103 census tracts. This indicator is calculated using census tracts of majority-white/black populations. Since there are no majority-black census tracts in St. Charles County, a score could not be calculated for this report.

What does this score mean?

A score of 100 represents racial equity, meaning there are no racial disparities in the outcomes between black and white populations. The lower the Equity Score, the greater the disparity.

For Transit Frequency, a score of 100 – a score reflecting racial equity – would mean majority-black and majority-white census tracts receive equal frequency of service. It is important to note that for this indicator, equity is not our only goal; we also want to improve outcomes for all.

WHAT DOES THIS ANALYSIS MEAN?

Majority-white and majority-black census tracts have a similar frequency of service. In St. Clair County, transit services majority-black census tracts 627,800 times per year, and majority-white census tracts 608,975 times per year. In St. Louis County, majority-black census tracts are serviced by transit 426,962 times per year, while majority-white census tracts are serviced 234,856 times per year.

On an annual basis, majority-white census tracts in the City of St. Louis receive transit service 266,641 times per year, while majority-black census tracts receive transit service 260,419 times per year. If transit in the City of St. Louis were more equitable, there would have been 6,222 more transit trips in each majority-black census tract in 2018.

Why Does Transit Frequency Matter?

The Ferguson Commission states, “Public transit is a key to expanding opportunity for all St. Louisans. A safe, reliable, affordable, and efficient public transportation system can increase access to health care, education, and employment.” Transit Frequency is a key component of transit reliability. Frequency of service matters a great deal to those who rely on public transit to get to work and for households without cars. While the Bi-State Development Agency currently provides equitable levels of service between majority-black and majority-white areas, there is greater demand and use for public transit in majority-black census tracts.

According to the 2016 American Community Survey, there are 14,000 residents of the City of St. Louis that work but whose household does not have access to a vehicle. However, workers who live in majority-black census tracts are three times more likely than workers in majority-white census tracts to not have a vehicle in their household. Given that, it should be no surprise that workers in majority-black census tracts are four times more likely than workers in majority-white census tracts to take public transit. All in all, workers who live in majority-black census tracts make up 60% of the estimated 14,400 city residents who commute via public transit. Similarly, demand for public transit disaggregated by race should be examined in St. Charles, St. Clair, and St. Louis Counties.

Which Calls to Action from the Ferguson Commission’s report are linked with this indicator?

Transportation is a signature priority of the Ferguson Commission to address economic inequality. The Ferguson Commission’s calls to action related to public transit include:

Questions for Further Investigation:

  • How can we increase Transit Frequency?
  • What can St. Louis do to reduce racial disparities in Transit Frequency?
  • What initiatives are currently underway to reduce racial disparities in Transit Frequency?

How can I learn more about this issue?

Each year, the East-West Gateway Council of Governments (EWG) develops a Transportation Improvement Plan for the St. Louis region. While the Bi-State Development Agency produces annual reports which summarize accomplishments and projects for the region, they rarely discuss transit service frequency.

Citizens for Modern Transit leads advocacy efforts for an integrated, affordable, and convenient public transportation system with light rail expansion as the critical component that will drive economic growth to improve quality of life in the St. Louis region.

Mobility For All By All is an interdisciplinary project based at Washington University in St. Louis that seeks to develop a series of equity metrics and engage residents to develop and execute site-specific collaborative community projects.
