Impact of Port Authority Route Eliminations
Posted on Wednesday, May 09, 2012 at 11:45 am ET
The Port Authority of Allegheny County has proposed a 35 percent service reduction to cope with a looming $64 million budget shortfall. These proposed cuts will eliminate 46 of 102 routes. Using route data provided by the Port Authority, we were able to create a map of the routes slated for elimination in September if the financial picture remains unchanged.
The proposed route eliminations and service reductions to Allegheny County's transit system will have a severe effect on many riders and communities, especially those losing service entirely. Using block-level data from the 2010 Census and the Census' Local Employment Dynamics Dataset, we estimate that 227,334 County residents will lose reasonable access* to transit from their residence, and 88,825 jobs will no longer be reasonably accessible from a transit line. Following the proposed eliminations, 53 percent of all County residents will still have reasonable access to transit from their home (down from 71 percent), and 71 percent of all County jobs will remain accessible to transit (down from 85 percent). The impact of route eliminations on residents and jobs is shown in the following table.
These affected areas are shown on the map below.
*We define reasonable distance as 2,000 feet (0.38 miles) from a transit line.
Is that 2,000 ft. flat from a line or does this take into consideration physical obstacles (hills, ravines, rivers, etc.)?

I'm glad you guys got this up on the blog. I'm pretty happy with the research I did.

We used the route lines that we converted from the Google transit feed specification. We selected blocks that had their centroid within 2000 feet of a route line, based on straight-line distance.

I am thinking that 2,000 feet may be understating the problem. It seems that the average distance between bus stops is considerably less that that, particularly in the city.
If that average is the true measure of the willingness to use public transportation perhaps it would be the best measure for this impact.
At any rate if would be interesting to see the difference with 1000 and 500 feet.
