AbstractThe purpose of this study was to evaluate the effect of drivers\\' utilization of amber time on starting delay, intersection capacity, and potential conflict, investigated, Four signalized intersections in Bangkok were A time-lapse photographic technique was used to gather the field data. Observations were made by reviewing the photographs to obtain the number of vehicles entering the intersection after the beginning of the amber phase .the entry time of the last vehicle on one movement, and the entry time of the first vehicle on the following movement. Statical distributions were used to analyze the observed data, Measurements were made of headways, time required for the last vehicle to clear the intersection, and starting delay, vehicular conflict were evaluated, Intersection capacity and potential Relationships were established to express the effect of the drivers utilization of amber ti.me on starting delays, intersection capacity, and potential conflict.
