Travel time is an important measure for assessing the operating efficiency of signalized arterials, evaluating the performance of traffic management strategies and developing realtime traveler information systems. An analytical model is proposed to estimate the travel times on arterial streets in real-time based on data commonly provided by system loop detectors (flow and occupancy) and the signal settings (cycle length, green times and offsets) at each traffic signal. The model is based on

The application of the proposed model on two arterial sites and comparisons of the estimated travel times with simulated and field data show that the model accurately predicts travel times at the selected sites.
