A Department of Transportation study released Friday shows just how out of control placard parking is in Manhattan.

The 187-page report [PDF], accompanied by some 223 pages of maps, was undertaken to assess "how placards are used in Lower Manhattan," and to determine if placard users are taking up more space than is allotted for them. The results should come as no surprise.

Key findings include:

• Curb parking spaces in Lower Manhattan are highly utilized, with 93% of all legal on-street
  parking spaces in Lower Manhattan occupied during the peak hours (9AM-5PM).
• Vehicles with agency and law enforcement permits, when combined with marked official
  vehicles (e.g., police cruisers, DOT bucket trucks), are a large share of the vehicles
  parked on-street, comprising 43% of vehicle-hours from 9AM-5PM. Law Enforcement
  placards are the major component of these vehicles (23% of all vehicle-hours). (A vehicle-hour is one vehicle parking for one hour. Thus, a vehicle that parks for three hours uses
  three vehicle-hours.)

• Nearly 1 in 8 permitted vehicles were illegally parked at a bus stop, crosswalk, fire hydrant,
  driveway, or were double-parked.
• Placards displayed by 9% of all agency and law enforcement permitted vehicles were
  deemed to be inauthentic or illegitimate in some way.

• Vehicles with agency and law enforcement permits use more of the parking supply than is
  allocated to them, occupying 49% more spaces than are allocated to them during the
  hours of 9AM-5PM.
• Vehicles with permits take space away from other designated uses such as curb space for
  commercial vehicles – 22% of loading zone spaces were removed from the commercial
  supply due to permitted vehicles parking in those spaces.
• Similarly, 18% of metered spaces were removed from the general public’s supply due to
  permitted vehicles parking in those spaces.
• Permitted vehicles park for longer periods, on average, than other vehicles, thus
  consuming disproportionately more space hours. Agency and law enforcement permits
  park on average for 4.0 hours compared with 2.7 hours for privately owned vehicles.
• 42% of agency business permits park outside of their dedicated parking supply for more
  than three hours, which is in violation of their permit.
• Over the course of a typical day (9AM-5PM) over 3,300 vehicles in Lower Manhattan
  display an LE permit, resulting in nearly 14,000 vehicle hours. This represents almost
  one-quarter of the total observed vehicle-hours in Lower Manhattan.
• The peak demand for agency and law enforcement permits is 5,805 and 13,494 vehicle-
  hours respectively, while their peak supply is only 7,052 and 5,937 space-hours,
  respectively. Therefore, while agency permits are technically parking within their allocated
  supply, vehicles with law enforcement permits use 127% more space hours than are
  designated for them from 9AM-5PM. This may indicate that the space allotment for law
  enforcement is not sufficient for its needs during those hours.

Data for the study was collected from September through November of 2006. 

Continuing its coverage of the placard abuse epidemic, the Times has a nice summary of the report, pointing out that the "biggest contributors to the parking crunch were vehicles with law
enforcement placards" — which "are also the most likely to park
in an unsafe way."

Among the nearly 700 vehicles
with placards that were spotted parked in crosswalks or at hydrants,
double-parked or parked in other hazardous ways, more than half
belonged to law enforcement.
