INTQ: A Mesoscopic Simulation to Analyze Intermittent Queues in Work Zones

Intermittent queue conditions may happen due to stochasticity in arrival or departure rate. This paper develops INTQ which is a mesoscopic simulation approach to estimate intermittent queue length and delay. In INTQ, traffic is divided into groups with different sizes. The minimum group size is one for single free flowing vehicles, and it is more than one for platoons of vehicles. Each group has certain characteristics, such as size, inter-group gap, and average speed that are generated from statistical distributions. Once a group is generated, it moves in the network under some rules, called Group Following Rules. The INTQ methodology is presented and applied for a work zone and simulation results are compared with field data.
