PARKING DIFFICULTY AND PARKING INFORMATION NEEDS FOR OFF-STREET SPACES IN THE CBD

As an ITS component, parking information systems have been deployed to alleviate parking difficulty. There is a void, however, in investigating the parking difficulty and its relationship with parking information, which is needed for justifying the implementation of a parking information system. This paper presented an investigation of impact of levels of parking information on parking difficulty, with the development of ordered probit models. By varying the level of parking information, the reduction in parking difficulty was quantified. The study presented in this paper is actually one part of a project. A survey was conducted in the project to collect data about parking difficulty and information and technology needs. The relationship between parking difficulty and information levels was presented in this paper, while the parking information and technology needs were presented in other papers
