Map Details - Service Areas for Mammography Clinics via Public Transportation, Georgia Counties

Return to Map Gallery

Impact Statement

This project constructed and used a geographic information system and network analysis to quantify spatial and temporal accessibility to mammography facilities in the Atlanta metropolitan area. This map shows the areas around each mammography facility that can be reached via public transportation in less than 45 minutes, less than 60 minutes, and less than 90 minutes travel time.

Service Areas for Mammography Clinics via Public Transportation

Purpose

This map highlights public transportation barriers to mammography facilities for those census tracts where the population was most likely to use public transportation.

Software Used

Network Analyst, ESRI, ArcGIS9.3, ESRI, Microsoft EXCEL

Data Used

U.S. Census data from 2000, TeleAtlas/GTD_ID boundary files, transportation files from MARTA, FDA MPRIS data on locations of certified mammography facilities, Georgia Cancer Screening Program facility locations.

Methods Used

Construction of multi-modal transportation network (rail lines bus routes, walk times, bus stops, rail stops, transfers) for Atlanta, GA. Calculation of mean travel time and distance to the closest mammography facility from population weighted centroids of census tracts.
