We were commissioned to produce VISSIM microsimulation modelling assessments at Thornleigh to determine the hourly capacity of heavy vehicle movements (associated with construction works) at key intersections in the area. Our investigations revealed that by adjusting signal timings – and staggering the release of construction vehicles to/from the site to minimise disruptions – there would be sufficient capacity to handle the additional demand of about 20 construction vehicles coming in and out of the site at certain times of the day.
