Artwork: A Simulation Model of Urban Arterial Work Zones

Several studies pertaining to the modeling of freeway and arterial traffic movements were reviewed, but none of them were applicable to lane closure in construction work zone on arterials. Hence the goal was to develop a computer-based methodology for the evaluation of traffic control systems at arterial street lane closure in the vicinity of signalized intersections. More specific objectives were to develop a microscopic computer simulation model of traffic flow at arterial street lane closures, to derive a series of system measures of performance as an output of the model, and to validate the model’s logic by using field data. Delay, fuel consumption, and queue buildup were used as the measures of effectiveness in validating the model. It was concluded that the model performs satisfactorily.
