- It can be a labor-intensive process to evaluate traffic control systems using hardware-in-the-loop simulation (HILS). To facilitate this process, tools will be developed for utilizing HILS efficiently and effectively. A Windows-based software will be developed to seamlessly execute batch runs, extract user specified output data in a useful format, and monitor time lags in controller and simulation operations. Statistical techniques, using the output data will be identified and tailored to the evaluation of traffic control systems across time and space. To make sure that HILS is applied appropriately, HILS application guidelines will be identified to aid users in determining when HILS should be employed to evaluate a traffic control system. By completing these tasks and developing these products, NIATT will be in a unique position for winning future projects for the evaluation of traffic control systems and for offering workshops on traffic signal systems.
