The NETSIM model has been used extensively to evaluate traffic control strategies for single intersections, arterials, and grid networks. Pedestrian control problems have been analyzed, bus system plans have been studied, and fuel consumption and emissions analyses have been applied to a variety of systems. Economic analysis has proved useful in many studies as well as for decision making in design projects. The coordination of actuated signal systems on arterials has been attempted with some success. Planning studies are presently under way. However, all the results and values (MOEs) derived from simulation are not precise field measurements. Simulation is a means of making reasonable approximations of operating control systems for comparison purposes. These approximations are useful and generally within accuracy limits in measuring traffic flow (daily and monthly variations, etc.). It provides a means to analyze problems that are difficult or impractical to approach by any other means. Results have been used for decision making in numerous problems, and no real failures have been experienced. NETSIM has been well supported by FHWA, and its continued support is urged. Capability to simulated, more advanced control technology is recommended. Plans are under way for some of these. Simulation of computer-controlled systems would be a desirable goal. This capability would help avoid costly and embarrassing errors in the design of those systems.
