Developing and Testing Proactive Signal Control Strategies for Arterial-Freeway Diamond Interchanges
| 项目名称： | Developing and Testing Proactive Signal Control Strategies for Arterial-Freeway Diamond Interchanges |
| 摘要： | This project proposed to develop a proactive traffic control scheme for diamond interchanges based on the recently developed Microwave Density and Analysis System (MIDAS) framework (a RHODES-type DP with better demand predictions). This project showed each potential interchange phase in the dynamic programming (DP) logic is actually possible paired phases at the individual interchange. The MIDAS DP will go through the vast number of possible durations for each of these paired phases (meta-phases), in a computationally efficient manner, and select the durations that optimize jurisdictions objective function, be is minimize delays, minimize stops, or a combination of these objectives. Cycle-free traffic proactive strategies that set phase durations for measured vehicle demand, such as RHODES, and respond well to regular as well as intermittent traffic smoothly without any �transition� issues. In Phase 1 of the project will develop the algorithms and the codes to optimize the durations of phases at the interchange, in response to the traffic demand from upstream intersections and off-ramp, and evaluate those analytically and experimentally using simulation models. In Phase 2 of the project, the project will include adaptive ramp meters for the on-ramps to consider delays on the arterial and the freeway. |
