This paper considers a specific driver information system whose objective is to reduce driver uncertainty in parking search by providing real-time information. First the paper analyzes the characteristics of parking search behavior and studies the parking waiting time particularly. A definition of DPUO (Dynamic Parking User Optimal) state is proposed to describe how vehicles will cruise in a network to find appropriate parking spaces given update information different from conventional studies. A discrete-time route-based variational inequality (VI) network model is formulated and the equivalence of the VI model and the DPUO problem is established. The model takes account into the factors such as updated information and crowding effects on the selections of parking spaces. The corresponding program based on the diagonalization method is developed to capture the traits of parking search in the network under the information system. Some issues about further research needs are also given.
