TRANSIT SCORE FOR ISRAEL

Revision 1.0

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

As of 1May2012 GTFS is Available in IL GTFS = General Transit Feed Specification

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.

• m_size = 5 • 500m square around grid element • weight_m = 0.8

• l_size = 9 • 900m square around grid element • weight_l = 0.5

• Grid_Score for each grid element =

1.0 * number of trips that stop in grid element + 0.8 * number of trips that stop in 500m square around grid element (but not in grid element) + 0.5 * number of trips that stop in 900m square around grid element (but not in grid element nor in 500m around grid element))
