New simulation framework quantitatively evaluates urban street designs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new simulation framework to quantitatively evaluate urban street designs, moving beyond qualitative principles. This framework models various road users, including autonomous vehicles (AVs), connected vehicles (CVs), and human-driven vehicles (HDVs), along with pedestrians and micromobility users. It assesses both safety and mobility, with a novel approach to conflict severity based on collision physics, and uses a genetic algorithm for design optimization. Initial application to Chicago's Belmont Avenue demonstrated that dedicated bike lanes improve safety at the cost of vehicle throughput, while increased AV penetration can reduce congestion and improve pedestrian interactions.

IMPACT Provides transportation planners with a predictive virtual testbed for evaluating street designs and quantifying mobility-safety tradeoffs.

    Complete Street Design informed by Multi-Agent Simulation

    Objectives: Complete Street design is currently guided largely by qualitative principles despite the increasing complexity of multimodal urban traffic. This paper develops a microscopic simulation framework for quantitatively evaluating alternative street designs by explicitly re…
