I just don't see how an active inspection system could work, especially in New York City where the quantity of people boarding is so great. It is not just the total number of daily passengers but rather the "surge" that occurs during the afternoon rush hour that becomes very difficult. According to the 2009 Hub Bound Travel Report from NYMTC (the most recent available) during the peak hour at Penn Station there are 13,387 passengers boarding 17 trains towards New Jersey, and 27,926 passengers boarding 35 trains towards Long Island, or a total of 41,313 for that peak hour. In a Congressional Research Service report from 2009, there was an assumption of a magnetometer service rate of 300 passengers per lane per hour. This would require 137 inspection lanes at Penn Station, assuming that the demand was uniform during the peak hour (in fact, demand is not uniform, and depending on the peaking factor, the actual requirement might be anywhere from 150 to 200 inspection lanes). On top of this would be the x-ray machines for all the keys, coins, briefcases, etc. At best I see a passive system (but then passive systems may have difficulty pinpointing any actual threats discovered). |
