More modern parking meters are generically called multispace meters (as opposed to single space meters) and control multiple spaces per block (typically 8-12) or lot (unlimited). While with these meters the parker may have to walk several car lengths to the meter, there are significant benefits in terms of customer service, performance and efficiency.^[14] Multispace meters incorporate more customer-friendly features such as on-screen instructions and acceptance of credit cards for payment—no longer do drivers have to have pockets full of coins. While they still may be prone to coin jams and other types of vandalism, most of these meters are wireless and can report problems immediately to maintenance staff, who can then fix the meters so that they are not out of service for very long.

With pay by space meters, the driver parks in a space, goes to the meter and enters the space number and makes payment. The meter memorizes the time remaining, and enforcement personnel press the bay buttons to check for violations.

Other advances with parking meters include vehicle detection technology, which allows the pay by space meters to know when there is a car parked in a space. This opens the door for benefits for parking managers, including providing way-finding (directing drivers to unoccupied spaces via the web or via street signs), enabling remote violation detection, and gathering vital statistics about parking supply and demand. Some meters allow payment for additional time by phone, and notify drivers when they are about to expire.^[15] Parking meters in Santa Monica use vehicle detectors to prevent drivers from "feeding the meter" indefinitely, and to delete remaining time when a car departs so the next car cannot take any time without paying.^[16] Meters in Madrid give discounted and free parking to drivers of hybrid and electric vehicles, respectively.^[16] Drivers can reserve meters spots in Los Angeles by cellphone.^[17]

Another advancement with parking meters are the new solar-powered meters that accept credit cards and still coins as well. Credit card enabled solar powered “smart” single-space meters^[18] were installed in Los Angeles in 2010, and Mayor Antonio Villaraigosa stated "the city's Department of Transportation had projected the 10,000 Coin & Card parking meters installed over the last six months would generate 1-1.5 million in revenue each year".^[19] These parking meters replace the top of the meter, but use the existing pole, and use solar power, which can help with sending technicians a wireless signal when in need for repair. DDOT (the District of Columbia Department of Transportation) states that this new parking meter will provide: "better return on tax payer's investment, a variety of options, reduced maintenance, a variety of easy payment options, and increased reliability".^[20]

New digital meters now account for all of New York City's 62,000 single-space parking meters, which are more accurate and more difficult to break into. New York City retired its last spring-loaded, single-space, mechanical parking meter – which was located at West 10th Street and Surf Avenue in Coney Island – on December 20, 2006. "The world changes. Just as the [subway] token went, now the manual meter has gone," said Iris Weinshall, the city's transportation commissioner, at a small ceremony marking the occasion, the New York Times reported.^[21]

Security issues

Parking meters are exposed to the elements and to vandals so protection of the device and its cash contents is a priority. The meters are frequently targeted in areas where parking regulations and enforcement are widely perceived to be unfair and predatory.^[22][23]

Some cities have learned the hard way that these machines must be upgraded regularly, essentially playing an arms race with vandals. In Berkeley, California, the cut-off remains of meter poles were a common sight during the late 1990s, and parking was largely free throughout the city until the city government installed digital parking meters with heavier poles in 2000 (which were eventually vandalized as well).^[24]

Legality in the United States

In a 1937 case in Oklahoma,^[25] H.E. Duncan contended that the ordinances impose a fee for the free use of the streets, which is a right of all citizens of the state granted by state law. The Courts ruled that free use of the streets is not an absolute right, but agreed with an unpublished 1936 Florida court decision that said, "If it had been shown that the streets on which parking meters have been installed under this ordinance are not streets where the traffic is sufficiently heavy to require any parking regulations of this sort, or that the city was making inordinate and unjustified profits by means of the parking meters, and was resorting to their use not for regulatory purposes but for revenue only, there might have been a different judgment."^[26]

One of the first parking meter tickets resulted in the first court challenge to metered parking enforcement. Rev. C.H. North of Oklahoma's City's Third Pentecostal Holiness Church had his citation dismissed when he claimed he had gone to a grocery store to get change for the meter.^[27]

The North Carolina Supreme Court judged that a city could not pledge on-street parking meter fee proceeds as security for bonds issued to build off-street parking decks. The court said, "Streets of a municipality are provided for public use. A city board has no valid authority to rent, lease or let a parking space on the streets to an individual motorist 'for a fee' or to charge a rate or toll therefor. Much less may it lease or let the whole system of on-street parking meters for operation by a private corporation or individual."^[28]

A 2009 lawsuit filed by the Independent Voters of Illinois-Independent Precinct Organization claimed the City of Chicago's 2008 concession agreement for the operation of its parking meters to a private company violated state law.^[29] In November 2010, portions of the suit were thrown out by the Cook County Circuit Court, including the claim that the city was using public funds unlawfully to enforce parking regulations after it was decided by the presiding judge that the city retained its ability to write tickets and enforce parking laws.^[30] However, the judge allowed other parts of the suit to stand, including an accusation that the city unlawfully conceded some of its policing power and its ability to set parking and traffic policy to the private company in the concession agreement.^[30] As of January 2011, the suit remained active, with the City of Chicago maintaining that the city retains all policing power, maintains responsibility for traffic management, and, through the concession agreement, retains control over rates.^[31][32]

Use in the United Kingdom

Parking meters were first used in Britain in 1958.^[33] They were used in most towns and cities although from c. 1980s they have mostly been replaced by Pay and display, pay on foot and Pay-by-phone parking.
