Probe vehicle based real-time traffic monitoring on urban roadways
Travel time of a signalized arterial link can be divided into four states. Link travel time distributions are approximated using mixtures of normal densities. Travel time distributions are estimated by signal timing and arterial geometry. Real-time travel time data can be used to identify the current traffic conditions. Distributions become more and more accurate by updating with real-time data.
