Abstract: Introduction; Smart cities want smart routing to saves fuel, cuts pollution and to handles traffic in real time. This work progresses the existing HEMO algorithm by incorporating eco-friendly parameters. Objective; In this paper, we propose two major enhancements to the HEMO-Routing algorithm. First, we add real-time traffic adjustment and a detailed energy-consumption model as new objectives. Second, we improve optimization by using an Adaptive Genetic Algorithm for broad search and Simultaneous Perturbation Stochastic Approximation for fine-tuning. Method; We test on the Extended Solomon Dataset (25 road segments with realistic distances, congestion, noise, emissions, and speed limits) in MATLAB 2021 on a Windows 11 PC (Intel i5-1135G7, 8 GB RAM). Compared to the original, our enhanced method boosts Pareto hypervolume to +12 %, cuts generational distance from by –18.8 %, lowers CO₂ from 152.4 g/km to 129.8 g/km (–14.8 %), and trims energy use from 8.75 kWh to 7.87 kWh (–10.1 %). It also converges in 200 instead of 250 iterations (–20 %), with only a 5.3 % runtime overhead. Result; These results show that our extensions deliver practical, eco-friendly routes with minimal extra compute, making the approach ideal for real-time smart-city applications. Conclusions; We made HEMO smarter by adding live traffic and energy-saving goals. With AGA and SPSA, it finds better, greener routes faster. Perfect for smart cities, and ready for EVs and bigger setups in future.
