The extNEMA system in "Part II" video clip, however, is limited in simultaneously fulfilling the operational efficiency and safety needs for automobiles. Its control logic reaches the decision for the time to terminate the current green simplistically based on identifying the "Gap-Out" (and "Max-Out") state instead of comparing traffic situations in current phase and next candidate phase. Accordingly, its decision-making process is void of key safety and operational factors which would have been incorporated into the control logic. To fill this void, George Lu developed an artificially intelligent traffic signal system to address these issues.

Due to the complexity in system design and implementation, the detailed description is omitted here (If interested, please refer to Journal of Transportation Research Record, No. 2259, pp. 96-111, 2011. My email: lu_xiaozhao@yahoo.com ). In general, this system provides full pedestrian protection for slow walkers via dynamic "FDW", as you are seeing, and also fulfills manifold vehicular needs in terms of timely service for heavy vehicular inflows, safer platoon dissipation, and shorter queue through underlying control logic (albeit not seeable).

The new system relinquishes a fixed walking speed as a timing input, which terminates the debate on "the most appropriate design pedestrian". Importantly, this research first addressed the issue of how to integrate all intersection users holistically into a systematic improvement framework by means of an innovative signal system which dynamically accommodates pedestrians and intelligently serves vehicles.
