According to research by the Institute of Transportation, the operation of the Taiwan High Speed Rail(HSR) has had a significant impact on the national expressway transport industry since it opened in 2007. To explore the operational efficiency of the routes that have offered national expressway transport service in recent years, this research has applied Data Envelopment Analysis(DEA) and analyzed two-year data from ten transport service routes, including five national expressways, three provincial highways, and two service routes in Yilan County. By means of distinguishing the input-output discriminating power, it was concluded that estimating "seat-kilometer", "salaries of driving and maintenance staff", and "cost of materials caused by driving and maintenance" as the input measures and using "incomes" and "passenger-kilometers" as the output measures served as the best method to evaluate the efficiency of the ten routes. The analysis result shows that the average technical efficiency of the five national expressway routes is better than those of the provincial highways and the routes in Yilan County. The top three efficient routes of the ten all serve on the national expressway, including Taichung - Kaohsiung, Taipei - Taichung, whose two terminals are similar to the HSR’s but more convenient than the HSR for connection to other places, and the Keelung - Hsinchu, one serves more northerly locations than the HSR does. Nevertheless, the Taipei - Kaohsiung expressway route has not been so efficient as although its terminals are similar to the HSR’s it is not superior to the HSR in transport connections, furthermore, its one-way service is over twice the time spent on the HSR. Additionally, on average, the routes served by the provincial highways and Yilan County roads are even less efficient. By adopting CCR and BCC models the reason for the inadequacies of those provincial highways can be found to be pure technical inefficiencies while the cause of those in Yilan County is due to scale inefficiency. In addition to building up an evaluation model and exploring the efficiency of every route, this research also evaluated the causes for inefficiency and provided directions for improvement. However, subject to data limitations, there are still incomplete parts that would need to be adapted.
