This era of technology and globalization has led to population explosion. Not only
new cities are emerging and booming but the existing cities are also getting overcrowded.
Each day thousands of new vehicles are being introduced to roads. However with the
existing infrastructure it’s difficult to accommodate these vehicles. This connotes that in
future, parking issues will pose a big challenge to facilitate traffic network and ensure living
standards of city. This calls for proper management of the available space on roads. The
Parking Guidance and Information System is one of important systems for Advanced
Traveler Information Services. This research proposes a parking guidance and information
system which integrates GPS and 3G network for a map on the Geographic Information
System to solution in adequate of road side information signboard. The system proposed in
this study mainly includes Parking Host, Parking Guidance and Information Server,
Geographic Map and Information System as well as Parking Guidance and Information
Browser. The study results show this system can increase driver’s efficiency to find parking
space and efficiently enhance parking convenience in comparison with roadside signboard
system.
