Transit score for israel v1 Presentation Transcript

  • 1. Transit Score for Israel Nachman Shelef nachman@miu.org.il +972544566016
  • 2. Transit Score USA
  • 3. Revision 1.0 TRANSIT SCORE FOR ISRAEL
  • 4. Transit Score uses GTFS • Transit Score is computed by processing the transit database provided in GTFS format • I used Python to process the GTFS files and to create the Transit Score files
  • 5. As of 1May2012 GTFS is Available in IL GTFS = General Transit Feed Specification • Enables many transit related indicators and tools including Transit Score Transit Agency New Transit New Transit Applications New Transit Applications Applications GTFS.zip Other Other Transit Other Transit Agencies Transit Agencies Agencies Transit Transit Application Transit Application Developers Application Developers Developers Transit Score General Public

  • 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.
