Abstract:

Improving travel time reliability is at the core of battling traffic congestion. This report summarizes the findings from a multi-institutional effort for analyzing and improving freeway travel time reliability. It first investigates the effect of incidents on freeway segment capacity, enabling the calibration and validation of the emergent travel time distribution for a baseline condition of a freeway facility using the Highway Capacity Manual approach. The report then develops a unified framework for assessing the freeway travel time reliability, and then it proposes a new strategy of controlling the headways of cooperative connected vehicles to improve travel time reliability. It also presents a prototype micro-level simulation application, GTsim, which analyzes freeway network performance under various types of Active Traffic Management (ATM) strategies, including those aiming to improve travel time reliability. Lastly, the report reviews the safety benefits of ATM strategies.
