Accurate estimation of route flow is crucial to traffic control optimization. Existing route flow estimation models are typically built upon strong assumptions on traveler route choice behavior or turn to data-driven approaches which heavily rely on prior OD estimation and high sensor coverage rate. This study proposes a route flow estimation frame...
During the last few decades, substantial interests have been devoted to determining the optimal number and location of sensors for route flow observability. However, the robustness of the observability system has received minimal attention. This paper develops a technique for obtaining the lower bound of route flow observability under a specific se...
Traffic congestion causes traveler delay, environmental deterioration, and economic loss. Most studies on congestion mitigation focus on attracting travelers to public transportation and expanding road capacity. Few studies have been found to analyze the contribution of different traffic flows to the congestion on roads of interest. This study prop...
