摘要：	The characteristics of traffic flow on suburban and rural two-lane highway, especially on upgrade and curve segments, are lack of understanding in Taiwan. The traffic flow characteristics on grade-segments of suburban and rural two-lane highway are significantly different from those on level segments. Institute of Transportation developed the Traffic-on-Grade Simulation (TGS-2L) model to support highway capacity analysis. This study applied the TGS-2L model to simulate the traffic condition on suburban and rural two-lane highways. Based on the results of the simulation, this study found that the variety of free-flow speed with various grade and length of grade, the variety of speed with grade and opposite flow rate, the capacity of uniform grade sections, etc. Finally, this study presented how to use TGS-2L model to find the level-of-service of suburban and rural two-lane highway. Moreover, a case study of Pei-Yi highway (Tai No. 9 highway) found the capacity are about 1,355-1,360 passenger car/hr each direction. The level-of-service could be acceptable when the volume increases 400 passenger car/ hr on northbound. That could be one of the countermeasures for dispersing northbound traffic of No. 5 freeway.
