What is it about?
Operators and planners of Parking Guidance and Information System (PGIS) often encounter the difficulty when and how to provide parking information to drivers in peak hours. The aim of this study was to assign the parking demands onto the urban network, find the positions suitable to locate the Parking Variable Message Sign (parking VMS), and try to solve the problem when to provide parking information to drivers. Parking VMS, as the most common forms of the information display terminal of PGIS, becomes the critical in designing PGIS.

Why is it important?
Parking Variable Message Sign (parking VMS), as the most common forms of the information display terminal of Parking Guidance and Information System (PGIS), has been equipped along roadside in many cities, and achieved rather good performances. However, operators and planners of PGIS often encounter the difficulty when and how to provide parking information to drivers in peak hours. Although parking VMS has been used for nearly ten years, and achieved rather good results, there is still no systematic regulation in evaluating the performances.
Perspectives
Incremental Assignment (IA) is a static traffic assignment algorithm with the fixed demands. Its iterations can reflect the dynamic changes of available spaces, in despite of not accurately. In the future, IA may be improved to solve the dynamic traffic assignment problem. If it is applied in the parking VMS location, the parking choice and the available spaces changing dynamically can be reflected well.
