This past Monday, we met with Owen Densmore, a computer expert with vast experience in data analytics and statistical modeling. Owen gave us a presentation on alternative methods of creating isochrones. The current code that we use for this involves plugging in a reference point and a matrix of other destination points, and returning the points which can be reached from the reference point in less than a certain amount of inputted time. While this method allows us to roughly determine isochrones for our reference points, it cannot be used to find all of the points on the isochrone.
Owen introduced an alternative method. He described starting an agent (representative of a human being) at a point of interest. The agent moves forward along a path, and splits into multiple agents at points where it could take multiple paths. As the agents move along the paths, the locations are recorded and the amount of time that it takes for the agent to reach each point is recorded. Using this method could result in an isochrone generator that can be applied to any location on Earth. Within the scope of our project our original methodology will be most ideal. However, we have added to this methodology by strategically picking destination points using census data. We also plan on plotting data using a tiling approach which will display isochrones in the traditional way.
