• Abstract:
  In this research, we studied green extension of a two-phased vehicle−actuated signal at an isolated ; intersection between two one-way streets. The green phase is extended by a preset time interval, referred to ; as critical gap, from the time of a vehicle arrival. The green phase switches if there is no arrival during the ; critical gap. We developed a model following a Poisson process that studied the intersection performance of ; traffic. We extended the model to cover the case of general traffic. Additionally, we derived system ; performance measures. Our findings show that our model is fairly flexible in accommodating freight traffic, ; and our model in the general case is asymptotically accurate under heavy traffic. Numerical tests show that ; the presence of critical gaps increases vehicle delay in most cases. This finding is enlightening regarding ; current practices.
