Toward a Systematic Exploration of the Influence of Route Choices on a Network Level of Performance

The aim of this paper is to quantify the impact of local demand distribution on the global network behavior, and, more precisely, to identify how route choices influence the level of performance of a network. A mesoscopic traffic flow simulator is chosen as an experimental platform to perform this analysis on an idealized urban center network. To simplify the exploration, route choice alternatives are clustered in homogeneous groups with respect to the percentage of overlapping. A large set of flow distributions among routes is evaluated, and different scenarios are then simulated leading to two main results. First, the fluid/congested boundary on the network is defined, and its sensitivity to parameters is evaluated. Then, route choice effects on the network level of performance are quantified using the network macroscopic fundamental diagram, which provides an aggregate vision of network behavior. Moreover, spatial distributions of traffic conditions are also investigated because heterogeneities are a well-known source of network underperformances.
