Traffic Flow Analysis: (A Spot Speed Study)

Abstract

This study seeks to determine the Spot Speed of vehicles passing through Kauswagan National Highway. This study primarily conducted to determine the 85 percentile of the spot speed which is typically used as the speed limit. This study adopted the descriptive method of research. It seeks to describe particular phenomena as they are. This method describes the nature of the situation as it exists during the time of study. The result of the data gathered will be used to determine if posted speed fits on the area and should it be changed. This study was conducted in Kauswagan National Highway, Cagayan de Oro City, where the imposed speed limit is 40 kph. The stopwatch method is being used successfully to complete this spot speed study using a small sample size taken over a relatively short period of time. This stopwatch method is a quick and inexpensive method  for collecting speed data. A number of 50 vehicles passing through Kauswagan National Highway were considered as the purposive sample of this study. Based on the data gathered, it was found out that 44 % of the drivers travelled along Kauswagan National highway are higher than the imposed speed limit. This only indicates that drivers view on speed design of the particular Highway is higher than the imposed speed limit. However, data’s also shows that 14 % of the drivers used speeds above the 85th percentile of the spot speed; thus it only means that 14 % of them are reckless. This research can help several communities and organization lessen the problem on traffic and congested roads today.  Keywords - Engineering, Traffic Flow analysis, descriptive design, Philippines. Â
