การประมาณค่าความจุของช่วงถนนโดยวิธี Indirect Empirical Methods

This paper aims to study and review the methodology for analyzing roadway capacity. This is an important principle in the design and planning of transportation and traffic facilities. The main contents of this article offer analytical procedures, sample study results, and considers the advantages and limitations of the Indirect Empirical Method, which is a method that can reduce the limitations of field surveys. This method consists of two approaches: (1) capacity calculation according to the manual, for which HCM is the most widely used; however, since this is a guide developed in the United States, it may not be applicable directly in areas where traffic conditions are different, and (2) capacity estimation using the traffic micro-simulation model. The latter approach has limitations on the input data and variables, but has the advantage of accurately simulating the conditions and driver behaviors, thus making the estimation of capacity more reasonable. By capacity estimation using the traffic micro-simulation model, it is possible to develop a roadway and highway capacity analysis in Thailand. There are still relatively. [ABSTRACT FROM AUTHOR]
