ATIP priorities and risk-based route scheduling preference involve primarily: 1. Inspector observations, regarding deteriorating or noncomplying track geometry,associated with structural conditions, e.g., crossties, ballast, etc.;2. A railroads compliance history, exception repeatability, degradation rate, and track quality;3. Duration between last inspections (i.e., between 2- and 4-year cycles where tonnage is more or less than 50 million gross tons, respectively);4. Passenger operation (i.e., Amtrak and applicable commuter/freight territories, such as Southeastern Pennsylvania Transportation Authority (SEPTA), Metropolitan Rail Corporation (METRA), Long Island Railroad (LIRR), Northeastern Illinois Regional Commuter Rail (NIRC), etc.);5. Designated hazardous material and strategic rail corridor network (STRACNET) routes;6. Railroad operating speeds greater than 20 mph, and 7. Other special regional needs or activities (e.g., the 2002 Winter Olympics in Utah).
