Determination of traffic flow parameters in different traffic flow interaction cases [PDF]
Transport, 2007 Modelling of straight road section consisting of one traffic line gives the opportunity to simulate “follow the car” system. In general it looks like a line of vehicles, going one after another.

Research on traffic state prediction method based on traffic flow prediction under multi-time granularity [PDF]
Scientific ReportsAccurate traffic state prediction is of great significance to effective traffic planning and management. The different characteristics of different sections and time-varying traffic patterns pose a challenge to the accurate prediction of traffic ...

Aircraft rerouting and rescheduling in multi-airport terminal area under disturbed conditions [PDF]
MATEC Web of Conferences, 2020 The disturbances, caused by resource competition, weather changes, and demand uncertainties, frequently occur and result in obvious fluctuations (e.g., the increase or decrease of demand and capacity) in demand and capacity.

On acceleration of traffic flow [PDF]
13th International IEEE Conference on Intelligent Transportation Systems, 2010 The paper contributes to the derivation and analysis of accelerations in freeway traffic flow models. First, a solution based on fluid dynamics and on pure mathematical manipulations is given to express accelerations. The continuous-time acceleration is then approximated by a discrete-time equivalent.

Still Flowing: Approaches to Traffic Flow and Traffic Jam Modeling [PDF]
Operations Research, 2003 Certain aspects of traffic flow measurements imply the existence of a phase transition. Models known from chaos and fractals, such as nonlinear analysis of coupled differential equations, cellular automata, or coupled maps, can generate behavior which indeed resembles a phase transition in the flow behavior.

Kinetics of clustering in traffic flows [PDF]
Physical Review E, 1994 We study a simple aggregation model that mimics the clustering of traffic on a one-lane roadway. In this model, each ``car'' moves ballistically at its initial velocity until it overtakes the preceding car or cluster. After this encounter, the incident car assumes the velocity of the cluster which it has just joined.

Adaptive Collision Avoidance for Multiple UAVs in Urban Environments
Drones, 2023 The increasing number of unmanned aerial vehicles (UAVs) in low-altitude airspace is seriously threatening the safety of the urban environment. This paper proposes an adaptive collision avoidance method for multiple UAVs (mUAVs), aiming to provide a safe

On the Fundamental Diagram of Traffic Flow [PDF]
SIAM Journal on Applied Mathematics, 2006 We present a new fluid-dynamical model of traffic flow. This model generalizes the model of Aw and Rascle [SIAM J. Appl. Math. 60 916-938] and Greenberg [SIAM J. Appl. Math 62 729-745] by prescribing a more general source term to the velocity equation.
