Abstract
A large problem in network analytic solutions is its representation of time. Or, more to the point, its lack thereof. GIS systems (Esri or QGIS) measure and represent time through distance-based metrics. That is to say, the measuring of Euclidian line data. And as such, distance thus derives time. The complexity of the problem grows manifold when considering the measurement of a mile-long line shapefile. If one travels, for example, along the mile-long line through, say, downtown Manhattan, and one travels the same distance outside of Manhattan, one quickly sees the obstacles growing complexity facing a network analysis. Given the difficulty of and the expense of having a reliable routing system, not to mention the trouble with school bus routing because of COVID-19, this project utilizes maintainable, and reproducible workflow for public servants and researchers alike. In short, this phase of the project posits a methodology to bring time back into the equation using NYC as the case study. The overall goal is to create a regional, multi-modal network dataset that gives walking, public transit, and driving times without requiring procurement by using Python, a GIS of choice, and Google’s Routing-API.
