With respect to stochastic delays at linked signals the solid quantitative information has not been available as yet. On the basis of field data the values of "I"(variance-mean ratio of flow) were related with the rate of flow. The stochastic delays with specific "I" values were obtained from the distribution of overflow queue, which were calculated by the use of Markov chains. The examination of the results led to the derivation of a simple method for calculating stochastic delays through the introduction of "I" into Miller's model. The good agreement was shown between the model and the field. The relationships between the cycle lengths and delays were examinated in a large number of conditions with regard to degree of saturation. signal split and link length. Within the practical range of cycle length uniform delays were dominant and no critical point was found in terms of minimum delay. In highly saturated conditions, however, the weight of stochastic delay is noticeable.
