Evaluating Configurations of Managed Lane Access Control Using Multi-commodity Link-Node Cell Transmission Model

Managed lanes have been regarded as an effective approach for managing traffic demand and reducing congestion. The configurations of manage lane access control can be generally categorized into two types - limited access and continuous access. A hybrid design of access control, called “partially limited access”, may result in better overall operational performance than the existing two types. In this paper, the authors present a multi-commodity Link-Node Cell Transmission Model (LNCTM) for evaluating the performance of different access designs. A two-layer network model is constructed to represent a freeway corridor. Instead of a route-choice model, we employ gap acceptance and lane change models to identify the split ratio for each commodity at each node. Some traffic phenomena observed on freeways with managed lanes, such as the cross-weave effect and the friction effect, are also incorporated into the model. The proposed LNCTM is calibrated and validated based on data generated from traffic microsimulation models. The LNCTM is used to evaluate the pros and cons of the different configurations of manage lane access control by considering road geometry, traffic demand, and driving behaviors. It turns out that continuous access have better overall performance, but placing buffers at adequate location can induce flow into managed lanes and mitigate the congestion at downstream freeway bottleneck such as lane drop area.
