Spatial Accessibility Modeling
In this lab students examine the use of GIS for modelling spatial access to facilities and services. Students learn the basics of network analysis using the Network Analyst extension by completing a number of tutorial. Next, students work through a simple example of measuring spatial accessibility, employing straight-line distance instead of network travel distance or time. Finally, students complete a spatial accessibility analysis your network analysis skills. The specific scenario is the closure of one of the branches of a community college to determine how many potential students are affected.
Student Learning Outcomes:
- Prepare data for use in network analysis
- Perform typical network analysis, including service areas and closest facilities
- Compare different approaches to measuring spatial access, including straight-line distance and network-based travel time
- Process and summarize demographic data based on metrics for spatial accessibility, including summary tables and cumulative distribution functions
- Implement a spatial accessibility model using network analysis for a given scenario
