Abstract: Intelligent Transportation Systems (ITS) technologies can supplement construction-based methods to improve the capacity of existing transportation systems. ITS then, presents viable solution to traffic congestion problems rather than focus only on the intensive road infrastructure developments and improvements. Baseline traffic information such as speed, and travel time along road networks, a fundamental knowledge-based resource used in traffic management, assessments and planning, can be obtained only through sustainable data collection system. Examination of ITS technologies shows that probe car survey system is a sustainable data collection method to gather real-time and historical traffic information. Key Words: ITS, probe car system, sustainable data collection system

1. INTRODUCTION 1.1 Background of the Study A concept on Intelligent Transportation Systems (ITS) introduced in the 1990s which has the goal of resolving road transportation issues such as traffic accidents and congestion through application of information and communication technologies is nearing its maturity stage in developed countries like Japan, United States and Europe. This key technology however, is still at its immature stage in the country. The component elements of ITS are shown in Figure 1. The main goal of ITS is to improve the overall efficiency of transportation systems by using
