Traffic Flow Theory and Simulation: 9. Lateral driving behaviour

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. The Dutch traffic (history and transport) policy will be discussed in this lecture. Different evaluation types and levels will be discussed, as well as how to monitor data and trends. This lecture also explains how to perform an evaluation or simulation study.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. This lecture discusses the behaviour of crowds and how to model them. The differences between car traffic and pedestrian traffic will be discussed so you will be able to apply the concepts of flow, density and speed to pedestrian flows.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. This lecture explains the gap acceptance theory and different models for motorway lane changing including the Mobil lane change model. The number of lane changes, merging and a theory for lane selection will be discussed as well.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. In this lecture the Wiedeman principle and how to draw the associated diagrams is explained. Action point modelling is discussed. The calibration of parameters of car-following behavior, capacity, capacity drop and the queue discharge rate are topics covered in this lecture.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. This lecture discusses the car-following model and how to calculate the resulting behaviour for the Newel, IDM and other models. Stability is discussed and it explained how to derive the fundamental diagram from a car-following equation.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. Lagrangian coordinates and the advantages of Lagrangian formulation will be elaborated in this lecture. The lecture also discuss how trucks influence the traffic stream and and introduces macroscopic fundamental diagrams.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. In this lecture some contour plots are analysed to see what phenomena occur. Phenomena like wide moving jams and standing queues are indicated during this lecture. Higher order phenomena in traffic flow like capacity drop, hysteresis and traffic instability are also discussed.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. In this lecture the method of characteristics is discussed and clarified with an example. An application of the kinematic wave model is also provided. Numerical solutions using the Gudanov scheme will be discussed lastly.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. In this lecture moving bottlenecks and queuing models are introduced and extensive examples will be given.

CIE4821. Master course fundamental traffic flow characteristics and traffic flow variables. In this lecture the 3 shockwave theory assumptions will be explained and a shockwave will be clearly and extensively defined. This lecture also discusses how shockwave equations can be used to predict the dynamics of congestion. Some applications will be given.
