7.5 Traditional Transit Market Analysis

The 2017–2021 Five-Year ACS estimates at the census block group level were used for the analysis ( see Table 7-3 ). Table 7-3: Transit Orientation Index (TOI) Indicators Indicators ACS Data Table Description

Density Threshold Assessment (DTA) illustrates the potential demand for discretionary transit markets by examining the relationship between population and employment density and propensity to use transit. Potential riders living or working in higher‐density areas are more likely to use transit. Using the 2017–2021 Five-Year ACS estimates at the census block group level, the number of dwelling units and the number of employees per acre were calculated and grouped as minimum, high, and very high based on a set of density thresholds. The population/ employment density thresholds for each transit investment level are listed in Table 7-4 . Table 7-4: Transit Service Density

For this analysis, the range of results was divided into four categories to demonstrate transit propensity, “Low”, “Medium”, “High”, and “Very High”. Figure 7-1 on the following page displays Transit Orientation Index (TOI) analysis in Key West Transit Service Area. The areas showing “High” and “Very High” transit propensity include Stock Island, New Town and Dredgers Key. The areas showing a “Medium” value are located along N Roosevelt Blvd extending into Old Town. In general, the existing transit routes provide a great service and coverage for traditional markets.

The identified high and very high-density of population and employment areas are concentrated in Old Town, Mid Town and New Town as well as Stock Island. The current transit routes provide coverage in those high-density areas.
