PROJECT DATA:

DESCRIPTION: The goal of this project is to improve mobility by developing a dynamic traffic metering methodology in connected urban street networks. The methodology aims at metering an optimal portion of incoming traffic at the boarders or inside the network to increase system-level mobility by avoiding long queues, queue spillovers, and gridlocks.

This study will generate the first network level formulation for dynamic optimization of metering rates in urban street networks. It will also incorporate connected vehicle information in the mathematical model and the proposed solution algorithm.

The project directly addresses the system-wide efficiency focus area by developing system-wide methods to improve mobility in urban street networks. In addition, the project directly addresses data-driven solutions in transportation networks as well as technologies to connected users and infrastructure systems as it fuses connected vehicle and point detector (e.g., loop detector) data and integrates them in mathematical models to optimize metering rates.
