Route guidance gives road traffic managers the possibility to improve traffic flows in a network. This paper investigates four promising algorithms used for calculation of decentralized route guidance by means of feedback control based on so-called splitting schemes. It appears that by using a link specific splitting scheme, simpler network modeling can be used. Based on this approach a framework is set up in which four different splitting schemes are evaluated, namely: bang bang, P control, inverse travel time and logarithmic splitting. The splitting schemes are evaluated in a simulation under varying conditions such as compliance levels, control interval, path formulation (explicit vs. hyperpaths), and 25 dynamic OD scenario’s. The outcome of 5600 simulations suggests that different controller’s each have a domain in the compliance/interval space at which they perform best.
