What You Will Learn
  • Learn the foundational concepts in suitability analysis, including absolute vs. relative suitability, attribute data measurement, and importance weights.
  • Learn the foundational concepts in linear optimization, including basic graph theory, Dijkstra’s algorithm, and corridor-siting.
  • Apply this knowledge by combining suitability analysis and corridor-siting techniques to site a new transit line.

Location decisions often involve the combination and evaluation of multiple data layers along with subjective criteria on the relative importance of each layer of data. With historic roots in landscape architecture and the development of early digital geographic information systems, suitability analysis techniques provide a systematic framework for evaluating possible locations in regards to a specific use case. Importantly, this includes the quantification of the subjective importance placed on various data layers. This course applies suitability analysis techniques and least-cost path analysis—which optimizes routes on linear features—to the case of planning for and siting a new transit line.

At the end of this course, you will understand the basic principles of suitability analysis and least-cost paths and be able to perform basic linear location optimization based on a set of quantitative and qualitative criteria.
