Smart City Traffic & Energy Grid (2D)

The 3D original wraps this sim's title in a decorative scene — randomly scattered buildings, holograms and neon cubes that flicker on a timer but never actually respond to a real control system. This 2D companion builds the mechanic the title implies instead: a working traffic microsimulation using the Intelligent Driver Model (the same car-following math used in real transportation engineering) running on a one-way street grid, with each intersection's signal switchable between a dumb fixed timer and an adaptive AI controller that reads queue lengths and only changes phase once the waiting approach is genuinely backed up. Alongside it, a solar + battery energy grid tracks a real two-peak household demand curve, a daylight-bounded solar output curve, and a battery state of charge integrated step by step from the surplus or deficit between them — so raising traffic density, solar capacity or battery size has a visible, physically grounded effect on both congestion and grid self-sufficiency.
