 The Links replace the city's network of 9,000 to 13,000 payphones, a contract for which expired in October 2014.
 The LinkNYC kiosks were devised after the government of New York City held several competitions to "reinvent" the payphone system.

 The original Swedish theory hypothesizes that pedestrian deaths are not as much "accidents" as they are a failure of street design.
