With the increasing number of city cars, traffic jams and parking difficulties have become a bottleneck of urban development. Creating the conditions to achieve the dynamic balance between road and automobile resources and allocate the parking resources reasonably is not only beneficial to the rapid development of cities, but also convenient for people to travel by bus or car. It can also ensure orderly parking, implementation of normative management, which can solve the problem of traffic jam and parking difficulties thoroughly. This paper takes the city of Hangzhou as an example, discussing the existing problems and countermeasures in urban parking planning and management. This paper first analyzes the existing problems in Hangzhou parking management from aspects, such as the serious shortage of parking lots, the lack of a clear management body, the inefficient use of car parks in some areas and lack of a long-term mechanism to attract social forces to participate in car park construction, and then proposes solutions to the problems from different aspects, such as giving full play to the pilot role of urban parking planning and management, establishing and improving the mechanism on parking lot management, and introduces social forces to participate in the construction and management of car parks, which provides reference for the planning and management of urban parking lot in China.
