duty. Decision to eliminate agents turned out controversial with both riding public and elected officials. Representatives were concerned about constituents’ jobs, whereas riders were concerned about susceptibility to crime. A 2004 compromise converted low-volume booths to high-wheels, high-volume booths to part-time entrances called “kiosks” (51) staffed by Station Customer Assistants (SCAs). Affectionately called “burgundy jackets”, SCAs do not sell farecards, instead they walk around solving customers issues, including fare machine usage. Agents' presence in the stations is disputed. A civil suit concerning the 2005 sexual assault at 21st Street station, which occurred despite the alarm having been raised by the agent. However, an agent saved a life in Cathedral Parkway–110th Street in 2010. The 2009 fiscal crisis necessitated more agent reductions, leaving only one 24-hour booth per station complex. Planned attrition program was converted to layoffs when fiscal situation deteriorated further in 2010. The only stations of the NYC subway which haven't 24-hour booths, although open 24/7, are the five stations of the IRT Dyre Avenue Line (5 line): Eastchester-Dyre Av, Baychester Av, Gun Hill Rd, Pelham Pkwy, and Morris Park. These stations are staffed only 15 hours for day. Prevention techniques Configuration In studies, gate evasion rate was found to be 1.5% unlocked, and only 0.8% when locked. Unlocked gates also invite more “questionable” entries; rate was 1.8% unlocked, but only 0.9% locked. Keeping gates locked potentially halves gate-related evasions. Following this finding, MTA reinstructed station supervisors and agents on importance and revenue impacts of keeping gates locked. Questionable gate entries decreased from 1.5% to 0.4% following this change, but illegal gate entries did not show statistically significant decrease when seasonality effects were accounted for. This measure seems to target mostly casual evasions. Originally fare control hardware and staff presence was thought to affect evasions. Unstaffed HEETs (with emergency exits), a generally unsupervised environment, might invite rampant evasions. However, pilot studies indicated these locations had similar gate evasions (0.9%) to staffed locations (1.0%). At least in New York, agents do not seem to deter evaders. Unsupervised HEETs had similar turnstile evasions (1.2%) to staffed locations (1.0%). Unsupervised exit-only locations have lower gate evasions (0.6%) than elsewhere, suggesting evasion is a crime of opportunity. Exit-only gates are only opened when trains arrive and passengers open them from the paid side; evaders likely find it more time-efficient to evade through entrances. Only the most determined evaders would wait at exit-only locations
