ANALYSIS OF EXISTING FORMULAS FOR DELAY, OVERFLOW, AND STOPS

An analysis is made of existing formulas for average delay, average overflow, and average number of stops for undersaturated conditions. The examination of these formulas covers a large variation in flows and cycle lengths, so recommendations are based on a thorough examination. The formulas examined are those developed by Webster, Miller, and Newell. It is concluded that the Newell formulas give the most accurate results. (Author)
