What is it about?
The first objective of this study is to develop models to relate stopped delay to control delay using DE algorithm (a metaheuristic approach) as a first attempt in the literature. Then, the advantage of using a variable conversion ratio due to stochastic nature of traffic, instead of a constant value (i.e., 0.76), for better delay estimations is explored by employing traffic and signalization parameters including volume, cycle length and green ratio with varying parameter values.

Why is it important?
The results revealed that the conversion ratio cannot be accepted constant usually taken as 0.76 for practical purposes since it is dependent on changing operation and traffic conditions. Therefore, it needs to be determined with the use of an appropriate model considering variable traffic conditions as functions of volume, cycle length and green ratio.
Perspectives
This paper shows that the conversion ratio between stopped and control delay can not be accepted as a constant value which is 0,76. It is investigated according to effective parameters which are volume, green ratio, and cycle length so on and found that the conversion ratio can change for different traffic conditions.
