A new microscopic model for car-following behaviour in urban traffic.

Traffic simulation is a powerful tool for developing and testing traffic control algorithms. Existing microscopic models are compared with measurements of the car-following behaviour under real-life conditions. It turns out that these models, originally designed for highway traffic, oversimplify the urban traffic dynamics. To overcome these shortcomings the new T3-model is proposed and its parameters are fitted to the measurements. First results show that this model is well suited to simulate urban traffic dynamics and to study the effects of new traffic control strategies.
