Summary Provincial highways serve as the important alternatives for national highways. When traffic congestion occurs in national highways, travelers often can’t get the information about the traffic conditions on these provincial highways. It makes travelers can’t choose their best paths, which results in the low traveler’s travel quality and the inefficiency of network as well as the high social cost.
  　In order to expand the provision of traffic information about provincial highways, this study discusses the feasibility of using buses, trucks, or other fleets as probe vehicles to collect traffic information. Additionally, the future impetus procedure is proposed. On the other hand, most of traditional vehicle detectors are foreign products. Thus, the costs are expensive, and the maintenance and other techniques are controlled by foreign agencies. Besides, these detectors can’t perform very well under the sophisticated domestic traffic environment, such as mixed traffic conditions. Therefore, the feasibility of researching and developing vehicle detectors by domestic industries is discussed. The prototypes of vision-based and microwave radar vehicle detectors are accomplished, and they are successfully verified. It indicates that the domestic industry has the potential to develop vehicle detectors. In order to provide the collected information for travelers and value-added business, the web-based platform for collecting, exchanging, processing, and broadcasting traffic information is developed. Through the discussion of fixed vehicles detectors and floating probe vehicles, this study expects to develop an efficient and inexpensive traffic information system so that the collection and provision of the domestic traffic information system can be enhanced.
