Travel distance/time and social activities among older African American

Travel distance/time and social activities among older African American

Description:
Transportation barriers to primary health care providers are one of the major health concerns in Flint, MI. Generally, Geographic Information Systems (GIS) has been used extensively as a method to examine spatial relationships between transportation and access to primary health care providers. Unfortunately, the Mass Transit Authority (MTA) did not have the complete directionality incorporated in their bus routes on the GIS data. Closest facility layer analysis is often used in health and spatial properties; however, lack of information in MTA data, limits accurate estimations. Route layer analysis is the additional estimation technique to correct this limitation to obtain absolute values without errors. The purpose of this study was to compare between the utilization of the closest facility layer analysis alone and the integration of both the closest facility layer and the route layer analysis to estimate the travel distance and time for patients to access primary health care providers. The ArcGIS 10 was used for these analyses. The results indicated that the closest facility layer analysis alone could not detect directionality on some bus routes. These estimation errors occurred when the locations of the primary health care providers were closer than transfer bus stops. In order to correct this error, the route layer analysis was implemented to correct the directionality of the MTA bus routes. The differences between corrected and uncorrected errors were 3.22 km and 4 minutes. Complexity of utilizing the multi-modal network to assess the barriers with access to care was observed
