In Korea, the implementation of a Freeway Traffic Management System (FTMS) was first initiated in 1992, and it has been in the process of an operational test since February 1995 on its 318-km sections of Kyoung-Bu and Chung-Bu express highways that connect Seoul and Daejon. This paper presents a set of evaluation results of the FTMS, based on both quantitative and qualitative perspectives. For quantitative analysis, delay time reduction due to an incident has been calculated, whereas for qualitative analysis, the results of a survey on satisfaction and other issues are presented. From the quantitative viewpoint, the monetary benefit accrued from the delay reduction with the installation of the FTMS, both for incident and non-incident cases, would amount to 65 and 9,320 million US dollars, respectively, up to the year 2004. Qualitatively, evaluation shows that 65% of highway users acknowledged the effectiveness of FTMS, 95% of users were satisfied with the accuracy of variable message sign (VMS) information, 68% of users wanted alternative routing information as additional information sources, and 96% of the driving population were quite positive on the expansion of the current FTMS.
