Car Path Tracking in Traffic Flow Networks with Bounded Buffers at Junctions
For researchers in traffic flow modeling, this provides a method to track individual trajectories in macroscopic LWR-based networks with buffers, but the contribution is incremental.
The paper models individual car paths in traffic networks with bounded buffers at junctions using coupled ODEs and PDEs, demonstrating the framework's use as a navigation device through computational experiments.
This article deals with the modeling for an individual car path through a road network, where the dynamics is driven by a coupled system of ordinary and partial differential equations. The network is characterized by bounded buffers at junctions that allow for the interpretation of roundabouts or on-ramps while the traffic dynamics is based on first-order macroscopic equations of Lighthill-Whitham-Richards (LWR) type. Trajectories for single drivers are then influenced by the surrounding traffic and can be tracked by appropriate numerical algorithms. The computational experiments show how the modeling framework can be used as navigation device.
