SFpark is San Francisco's system for managing the availability of on-street parking. Taking effect in April, 2011, the program utilizes smart parking meters that change their prices according to location, time of day, and day of the week, with the goal of keeping about 15% of spaces vacant on any given block.〔(High-tech parking meters premiere in S.F )〕 The San Francisco Municipal Transportation Agency launched the system with congestion mitigation funding from the Federal Highway Administration in July 2010〔(Press Release: FHWA Deputy Administrator Helps Launch SFpark in San Francisco, 4/21/2011 )〕 as a fallback from a downtown cordon.〔San Francisco congestion pricing〕 It is the first system of its kind in the world. The system seeks to reduce the time and fuel wasted by drivers searching for an open space.〔Matt Richtel. NY Times. (Now, to Find a Parking Spot, Drivers Look on Their Phones. ) May 7, 2011.〕 Parking usage is monitored via sensors placed in the asphalt,〔 and the availability and prices can be checked via SFpark.org, iPhone and Android apps, and cell phone.〔〔(SFpark: The phone app that tells you where the parking spaces are | Mail Online )〕 Prices can range from a minimum of 25¢ to a maximum of $6 per hour during normal hours, with a $18 per hour cap for special events such as baseball games or street fairs.〔(Pricing – SFpark )〕 , prices range from 25¢ to $6.00 per hour during normal hours.〔(Data – Resource Types – SFpark )〕 In addition to the on-street parking, fourteen city-owned garages are included in the program.〔(SF Launches Another Parking App That Appears To Require Cell Phone Use (Or A Navigator) While Driving: News: SFAppeal )〕 This concept of market-based variable pricing or "performance parking" has long been advocated by transportation researcher Donald Shoup, now an adviser on the project.〔 ==Results== By December 2012, average hourly parking rates had dropped by 14 cents from $2.73 to $2.59, SFMTA's revenue from parking citations dropped from 45% to 20% of total parking revenue, and 6% of the new meters charged 25¢ an hour.〔(SFpark hourly meters actually saves motorists money | Transportation | San Francisco | San Francisco Examiner )〕 A March 2014 study found that SFPark met its 60-80% occupancy goal and that cruising for parking is down by 50%. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SFpark」の詳細全文を読む スポンサード リンク
