       The “Taiwan Highway Capacity Manual” was published by the IOT in 1990 with revisions in 2001 and 2011. In addition, IOT further developed the“2011 Taiwan Highway Capacity Analysis Software (THCS),” based on the “Taiwan Highway Capacity Manual (2011 edition)”to improve the ease of analyzing highway capacity. With these tools, analysts can not only perform accurate numerical computations but also understand operations and deliver results in a short period of time. This is beneficial to road planning and design, and facilitates the formulation of road operation strategies. The THCS software is now widely used in numerous highway capacity and service standard assessments such as urban renewal planning, traffic impact assessments and newly built roads (such as adding and  improving highway interchanges).
       In order to improve the convenience, user-friendliness, compatibility, and applicability of THCS, and to promote the initial results of recent highway capacity research, the major works this year was focused on updating the THCS software, revising the software manual, maintaining the website and providing training, while an expert was employed to provide consultation services on high capacity analysis. Also, materials were produced showing the important results.
