  • Investigation of Centroid Connector Placement for Advanced Traffic Assignment Models with Added Network Detail
    Transportation Research Record, 2015
    Co-Authors: Ehsan Jafari, Mason D Gemar, Natalia Ruiz Juri, Jennifer Duthie
    Abstract:

    Advanced traffic assignment models, such as simulation-based dynamic traffic assignment, typically incorporate more Detailed Network representations than do traditional planning models. In this context, the placement of centroid connectors may have a significant effect on model performance, and attention must be paid to their number and location to avoid unrealistic congestion or low utilization of minor roadways by local traffic. Given that the manual inspection of centroid connector placement may be too time-consuming in large regional Networks, this paper proposes two simple automatic centroid connector placement strategies for dynamic traffic assignment applications. The first approach radially distributes the connectors to the nearest nodes and is intended to exemplify some limitations of the most common techniques in practice. The second strategy involves dividing the centroid and subsequent demand into two parts, distributing the demand across one subcentroid linked to nearby nodes and one linked t...
