|Abstract:||An online self-estimation algorithm is developed to jointly estimate the states describing the traffic flow dynamics in a signalized junction under different traffic conditions, together with model parameters and their uncertainties. The proposed novel methodology is based on the Expectation-Maximization algorithm and Robbins-Monro stochastic approximation. The algorithm is validated by simulating a typical signalized 4-arm junction. This algorithm could form part of an adaptive control loop for traffic light systems that is able to autonomously adjust to changing traffic conditions.|
