Summary | The Institute of Transportation (IOT), Ministry of Transportation and Communications,plans to publish an updated version of Taiwan Highway Capacity Manual (THCM) in 2018. Toaccomplish this mission, IOT initiated a three-phase project in 2016. The focus of the first phase of the project is on the calibration of the 2016 HTSS (HighwayTraffic Systems Simulation) Model and the revision of Chapter 1 Introduction, Chapter 2 BasicConcepts, and Chapter 12 Rural Two-Lane Highway. The revision of Chapter 12 encompasses the following tasks: (1) synthesize field data, (2) develop and calibrate the 2016 HTSS Model, (3) develop methodologies for capacity and levelof-service analyses of rural two-lane highways, (4) prepare a draft revised Chapter 12, and (5) prepare the 2016 HTSS Model User Manual. The traffic flow characteristics on rural two-lane highways are governed by a number offactors, such as geometric design (e.g., grade, length of grade, and radius of horizontal curve),speed limit, acceleration capabilities of vehicles on grade, and driver behavior. The interactions of these governing factors result in complex traffic operations. Therefore, the capacity analysis methodologies developed in this phase rely heavily on the 2016HTSS Model for analyzing twolane highways with grades or passing maneuvers. This report describes in detail all the tasks carried out in the first phase and the results |
