%0 Journal Article %T Analysing adjustment factors for using lanes at traffic-light-controlled intersections in Bogot¨¢, Colombia. %A Ricardo Jos¨¦ Pe£¿a Lindarte %J - %D 2010 %X This article was focused on analyzing the lane use adjustment factor (fLU) forming one of the eleven adjustment factors proposed in the current calculation methodology contained in the 2000 version of the Transportation Research Board¡¯s (TRB) Highway Capacity Manual (HCM) for analyzing traffic-light-controlled intersection capacity in terms of saturation intensity. A methodology was established when analyzing the fLU factor that considered operational conditions regarding traffic-light-controlled intersections in Bogota. Road traffic flows were analyzed, including characterizing road traffic based on statistical sampling, field data collection and analysis. The project proposed equations allowing reference values to be gathered for determining adjustment factors regarding lane use on roads in Bogota in relation to existing access typologies and road traffic volume for analyzing traffic-light- controlled intersections. For example, in the specific case of roads having direct double-lane access (2CCD), the basic equation was determined to be y=-3,03E-08X2+3,44E-05X+0,888988, having a 1.0 coefficient of correlation. The dependent variable y referred to the fLU factor and the independent variable X was the volume of road traffic in mixed vehicles/hour. This equation was considered to be statistically relevant. A comparative analysis of the lane use adjustment factors estimated in the project is also presented and compared to the values recommended by the US Highway Capacity Manual. The project¡¯s conclusions and re- commendations were thus sustained, validating the recommended factors summarized by the HCM and recommending that the results obtained from the project should be used in traffic-light-controlled design and planning projects %K traffic-light-controlled intersection %K saturation flow %K service capacity and level %U https://revistas.unal.edu.co/index.php/ingeinv/article/view/15199
