Summary	The Institute of Transportation (IOT) conducted a national-wide travel survey in 2014 to better understand weekday and weekend intercity travel behavior in Taiwan. A supplementary travel survey was carried out in 2015, based on the previous survey in 2014. The main objective of the two-year survey is for updating the 2013 Transportation Demand Model, for its applications to transportation system analyses. In addition, the results of implementation of the 5th Taiwan Area Comprehensive Transportation Planning Research Series may be presented. Major research findings from this year’s surveys include the following: While the ridership of public transport has continued to increase, the growth rate of car trips on freeways is even higher than that of public transport due to the great decline of fuel price. The number of total trips produced in 2013 has increased considerably from that of 2010. Specifically, weekday car trips in 2014 have increased by 70 percent, while weekend car trips increased by 40% in four years. The supplementary travel survey and its statistical test analyses were completed. A total of 6,364 valid questionnaires were collected in 2015, which increased total sample size to 10,973 questionnaires for weekdays, and 17,334 questionnaires for weekends. According to the study, the trip characteristics on weekdays and weekends show that: (1)The length of trips by different transport observed with the use of properties, accounting for the use of public transportation with a length longer journey times and decreased high-speed rail, aviation and the longer the length of journeys with its operation with higher proportion; whereas the locomotive the following main 50 km journey times. (2) Cross-living circle journey times object properties, weekday journeys to work journeys based, non-holiday places a higher proportion of journeys to work. Commute to work more use of locomotives and passenger cars, commercial aviation business trip places and high-speed rail-based. The surveys of passengers’ before-departure and after-arrival travel behavior in Taichung and Kaohsiung International airports were conducted. The surveys show that the major transport mode of passengers in both airports is car for both airports. About 90% of the air passengers originate from cities nearby. The possibility of incorporating reliability performance measures into the transportation demand model was evaluated. A regression model may be built to identify the relationship between perceptive reliability and actual reliability. It is recommended to develop regional models for Taiwan, so that major cross area transportation issues may be analyzed in the future. The regional models may be used in analyzing projects as distance-based highway toll collection, Taiwan Taoyuan International Airport MRT, the three new stations of Taiwan High Speed Railway, and SuAo-Halian Highway Improvement Project. In addition, issues as full implementation of standard 40-hour workweek, and low birthrate and aging issues may also be accurately evaluated in detail by using the regional model.
