Floating Car Simulation for Evaluation of Urban Main Corridors Based on a Macroscopic Traffic State

The coordination of “main” corridors is an important issue of adaptive signal control for urban networks. A wide range of adaptive signal control algorithms relies on the optimization of a performance index. Traffic models (preferably simple ones) are used to calculate the performance index during the optimization procedures. Scoot as well as Sitraffic Motion relies on the propagation of cyclic traffic flow profiles. Other methods rely on traffic network simulation approaches such as cell transmission models. The pure performance indices calculated by all these models, however, do not allow for an assessment of the optimization results from a traffic engineering point of view: for example, different solutions can be represented by the same numerical value of the scalar performance index. This contribution presents an approach that allows the movement of a single floating car to be generated by emulating its movement out of given macroscopic model calculations and a given starting point. Two car following models are compared: a simpler model derived from Newell (2002), and a more sophisticated model derived from Gipps (1981) enhanced by a signal model.
