Stochastic Gradient-Based Optimal Signal Control With Energy Consumption Bounds

IEEE Transactions on Intelligent Transportation Systems, 22(5), 3054–3067.

author keywords: Energy consumption; Optimization; Delays; Linear programming; Stochastic processes; Mathematical model; Fuels; Traffic signal optimization; fuel consumption; simultaneous perturbation stochastic approximation (SPSA); vehicle-specific power; gradient approximation; SPSA with constraints
TL;DR: A novel gradient-approximation-based solution technique offers a functional and feasible way to accommodate non-convex energy consumption bounds within a signal control optimization model to achieve maximal mobility with minimal energy consumption. (via Semantic Scholar)
