  • 8. Transit Score for Israel Revision 1.0 • • • • A 100mx100m grid is overlaid on the entire area of Israel A GTFS file is created by geo-filtering any part of Israel from the GTFS file of all of Israel. Geo-filtering is based on a polygon that surrounds the area of interest. This could be a region, a single city, a neighborhood, or the entire area of Israel. A Grid Score is computed for each grid element using the filtered GTFS file (as described in the next slide) The Transit Score (between 0 and 100) for each grid element is calculated by normalizing the Grid Score – Transit Score(i,j) = 100 * Grid Score(i,j) / Max Grid Score of IL • • • The Transit Score for each grid element is mapped to a color spectrum from red through orange then yellow to green. So that 100 is bright green and 0 is dark red. The color spectrum is adjusted so that green is good, yellow is ok, orange is bad and red is terrible. (sounds easy – it turns out to be difficult) A KML file is generated that includes a polygon of each grid element (that is not zero. i.e there is at least one bus station within a 900m square around the grid element where at least one bus stops) with the color corresponding to its Transit Score. The KML file can be viewed by running GoogleEarth. – Note that for large files you need to install the GoogleEarth application. The pug-in for GoogleMaps only works with small files. – Note too that the large files cause GoogleMaps to work very slowly. • I captured screen shots from GoogleMaps and copied them into this presentation in the following slides.
