Abstract: This paper presents a method for estimating freeway travel times in real time directly from flow measurements, which is desirable for present and future Intelligent Vehicle-Highway Systems (IVHS) applications. An inductive ...

Abstract: This paper presents an analysis of freeway traffic flows under congestion based on the principle of traffic dynamics, using the example of recurring congestion. Queuing and discharging mechanisms are analyzed using the ...

Abstract: Highway infrastructure management requires enabling computer tools to facilitate the decision-making process. A Decision Support System (DSS) for one of the nine districts in the Commonwealth of Virginia was developed ...

Abstract: Levels of Service for infrastructure systems should be defined in terms of both capacity (Level of Availability) and maintenance (Level of Operation). Levels of Service for a highway system consider capacity, but assume ...
