For Winston-Salem residents without the means or ability to drive, the bus system plays a critical role in determining their ability to reach jobs, education, medical care, child care, public benefits, and community activities. The Business 40 infrastructure improvement project presents an opportunity to consider the mobility of all Winston-Salem residents and to focus on how the bus system can be used to advance health equity in our community.
The NC DOT has designated funds to expand bus service during the Business 40 closure.
The analysis in Table 1 reflects the current total amount of time it takes citizens from each ward (Map) to reach key healthcare access locations, prior to any increase in transit services.
These data are a baseline from which to measure how improvements in bus service impact the amount of time residents spend traveling to health services.
Our analysis utilizes the Google Transit API (Application Programming Interface) to calculate optimum transit duration from multiple locations in each ward to the major health assets in the community. (Note: Novant Medical Center and Wake Forest Baptist Medical Center are along the same bus routes and are separated by +/- 5 minutes on the bus.)
The API allows for calculation of additional details about the trip, including:
Economic mobility in Winston-Salem is a pressing concern. For those without the means or ability to access private transportation, it takes a disproportionately greater amount of time to reach important health care assets. The Business 40 closure affords an opportunity to consider how the bus system influences residents’ ability to access to health services, and how improvements to bus services may enhance health care access and utilization. This brief analysis is limited to data regarding health care access, though Google API can be broadly used to document transportation equity within our community. Further critical thought about the impact of NC DOT Business 40 closure mitigation funds should be ongoing. We anticipate the expanded bus services will support a more equitable and just public transportation system.
 WSTA has provided Google bus schedule and route information for display on Google Maps. The Google Transit API makes this data available for querying based on specific start times, start locations, and destinations. The addresses utilized for this analysis are available here.
